RSA Replay: Mind Change - Susan Greenfield

The video included here is of "Baroness" Susan Greenfield speaking at The RSA about her new book, Mind Change: How Digital Technologies Are Leaving Their Mark on Our Brains (to be released in the U.S. in January, 2015). Her talk was mired in controversy before she ever opened her mouth (see the details in the first companion article below).

Besides the video, I am sharing two articles from The Guardian, both of which are critical of her and her new book, and her refusal to debate other neuroscientists about her "findings."

RSA Replay: Mind Change

Leading neuroscientist Susan Greenfield considers the vast range of technologies that are creating a new environment around us, and asks: how can we ensure these powerful forces bring out the best in us, and allow us to lead more meaningful, more creative lives?

Despite the fact that Susan Greenfield is a regular contributor to The Guardian, two recent articles take her and her new book out behind the woodshed for a beating. Here are both of them - and the second one is a very detailed take-down of her social commentary parading as science.

Susan Greenfield: why is she reluctant to engage with 'mind change' critics?

Baroness Susan Greenfield has a new book out, which means that she’s back on the media circuit to promote her controversial ideas about how technology affects our brains. In her latest foray on Thursday she gave a lecture at the RSA in London on “Mind Change’, an event mired in controversy before a single word was uttered.

In the lead-up, the author of Bad Science, Ben Goldacre, claimed that he was originally approached to chair the discussion but the Baroness objected to his taking this role, at which point the RSA (rather ironically) changed its mind and retracted its invitation to him.

We contacted Greenfield to verify this claim and she responded through the RSA’s director of external affairs, Nina Bolognesi. Bolognesi stated that “Dr Goldacre was invited by the RSA to chair an event with Professor Greenfield. However, Professor Greenfield’s preference was to have a balanced debate with Dr Goldacre, on a subject where the title was mutually agreed, with Chair holding a neutral view. On Sept 2nd Dr Goldacre declined this offer as he felt he was not an expert on the topic being presented by Professor Greenfield.”

It’s frustrating that the RSA was not more assertive in its original suggestion for the event – it would have been refreshing for the charity to host a more honest, critical debate, and Goldacre would have made an excellent chair.

Aside from this though, the RSA event was disappointing for other reasons. You can watch a recording of it here [posted above], and it’s worth noting that the chair appears to make an effort not to solicit any questions about Greenfield’s position as a controversial public figure. At the outset, Greenfield asks the audience not to use Twitter during her talk – thus attempting to shut down free debate of her ideas, and attempting to impose a didactic, one-way flow of information. If anyone were in any doubt that the Deficit Model is still alive and kicking, then this serves as a reminder that there is much work to be done.

What we’re starting to see in some of the interviews with Greenfield is a gradual amplification of criticisms she has faced over the last few years. The most prominent criticisms were posed by Goldacre in 2011, when he asked why the Baroness refuses to publish her claims within a scientific journal, where they can go through the usual process of scientific scrutiny and peer review. Her response to this has been varied. On the BBC last year, she retorted with “How can I publish just one paper?”. In other interviews, she argues that it shouldn’t matter who publishes on the matter – in her own words “It doesn’t make it more or less valid if I’ve done it or if someone else has.”

No one has ever reasonably asked any scientist to produce a single study to substantiate any one claim. That’s simply not how science works and Greenfield can’t possibly be so na├»ve as to believe otherwise. But her responses cast an either-or mindset; either you can produce one study, or nothing at all. This is a bizarre standpoint because there is a wealth of studies that could be run – and are being run – to look at all sorts of aspects of technology use, and we’ve discussed some of them here before. Only by running relevant studies can we move beyond the same old surface-level debates about simplistic concepts (like screen time) that don’t have much bearing on the real world.

Most critics of Greenfield don’t take issue with her voicing an opinion. It’s perfectly acceptable to have a view on a subject without having conducted research in that area. However, when you position yourself as such a prominent and persistent advocate of a particular view that has a testable scientific base, you should lead by example – especially when you are a scientist yourself. Develop expertise in that area. Force your arguments to stem from evidence, never from authority. What better way to silence what Greenfield sees as personal criticism than to actually do the research? Greenfield has had more than enough time and funding to lay her cards on the table.

But of course this hasn’t happened. Instead we’re subjected to the same tired arguments and rhetoric. Through what can only be described as a campaign of media manipulation, Greenfield shows that she is afraid of what actual data might reveal. She has adopted the mantle of the pundit who attempts to hoodwink her audience into confusing her personal views with hard facts. But the public isn’t so easily fooled by scaremongering. While the RSA debate offered no insight on “mind change”, it shows one thing clearly. Greenfield has become lost in a sea of her own ideas and is either unwilling or unable to add anything meaningful to the debate about technology.

Mind Change: Susan Greenfield has a big idea, but what is it?

A poorly researched diatribe on the ‘youth of today’, Susan Greenfield’s exploration of Mind Change reads like a Littlejohn column wrapped in the trappings of science

Bland, logical statements

12 February 2009. In the House of Lords chamber at the Palace of Westminster, Lord Harris of Haringey holds the floor. “My noble friend had some unfortunate experiences when he placed his profile on Facebook a couple of years ago,” he explains, “receiving what the Sunday Times describes as an avalanche of suggestive comments of the ‘Hello, sailor’ variety.”

The Lords have met to hold a debate on the use of social networking sites by children, and the adequacy of safeguards to protect their privacy and interests. As Harris concludes his opening remarks, the Baroness of Ot Moor, Susan Greenfield, rises to her feet to make a statement. There are two different accounts of what happens next.

The first appears in the opening pages of Baroness Greenfield’s new book, Mind Change. One of few scientists to hold a seat in the upper house of Parliament, she tells us that she “decided to present a perspective through the prism of neuroscience,” explaining to the assembled peers, “firstly, the human brain adapts to the environment; secondly, the environment is changing in an unprecedented way; so thirdly, the brain may also be changing in an unprecedented way.”

Greenfield claims to find the controversy that followed inexplicable: “The reaction by the international print and broadcast media to this seemingly bland and logical statement was out of all proportion to its content. Needless to say, I had to endure the inevitable press misrepresentation resulting from a priority of selling copy over actual truth: ‘Baroness says computers rot the brain’ was just one of the more lurid headline-grabbing efforts of one sub-editor.”

The second version comes from Hansard’s official record of what was spoken in the House of Lords that day. “It is hard to see how living this way on a daily basis will not result in brains, or rather minds, different from those of previous generations,” the Baroness explained. Answering her own question, “what might now be in jeopardy?” she listed attention spans, the ability to delay gratification, and empathy. “The mid-21st century mind might almost be infantilised, characterised by short attention spans, sensationalism, inability to empathise and a shaky sense of identity.”

In the five years since that debate, Greenfield has continued to drop her unique brand of “bland, logical statements” on the public with predictable results. Her articles in the press state, in her own words, “one simple fact: the human brain, that most sensitive of organs, is under threat from the modern world.” We are told that our brains are under “widespread attack”; we must wake up to, “the damage that the gadget-filled pharmaceutically-enhanced [world] is doing to our brains”; and sites like YouTube are causing, “the fragmentation of our culture.”

Over the same period, the Baroness has faced growing criticism from leading figures in science and medicine, such as Ben Goldacre and Oxford neuropsychologist Dorothy Bishop. Their request to her is simple: please stop writing op-eds for the Daily Mail, and start presenting your findings in an appropriate peer-reviewed forum.

Mind Change isn’t peer-reviewed, but it’s the closest thing so far to a response. In it, Greenfield lays out her entire argument for the first time; 385 pages of neatly referenced reckonings on the state of our brains and technology’s role in changing them.

Hipster Galileo and the Brain Apocalypse

So what exactly is Greenfield’s idea? In 2012 I wrestled with this question, piecing together fragments from her various articles, and concluding the following. “Greenfield’s hypothesis is that an unknown level of exposure to an unspecified subset of modern technologies may be affecting an indeterminate number of people’s brains in an undefined way, with a number of results.”

I wasn’t far wrong. “The argument underlying Mind Change … goes like this: the human brain will adapt to whatever environment in which it is placed; the cyber world of the twenty-first century is offering a new type of environment; the brain could therefore be changing in parallel, in correspondingly new ways.”

The similarity with “climate change” is deliberate of course. Greenfield compares herself to the plucky pioneers of the green movement in the 1970s and 1980s, fringe groups fighting against the tide whose ideas would soon explode into the mainstream, defining one of the key debates of our generation. She writes as if she sees herself as a sort of lead hipster of the forthcoming brain apocalypse.

The comparison doesn’t work though. Whatever your views on climate change, the phrase represents a clear and testable idea. Human processes are generating carbon dioxide. This accumulates in the atmosphere, at higher levels than would occur naturally. The extra CO2 traps heat that would otherwise have radiated out into space. Storing this extra energy in our skies, land and oceans leads to higher average temperatures and more volatile weather.

Sure, there are complexities and nuances and caveats and exceptions and all the usual baggage that comes with making predictions about a complicated world; but the basic idea can be written down and understood. You can make predictions from it that people can take out into the real world, measure, and test.

Greenfield can’t say the same for her idea, because there just isn’t enough substance to it. Brains adapt to new things, our environment has changed rapidly over the last few hundred years, and presumably this has some effect on us. Nobody really disputes that, but what effects exactly, and through what mechanisms? Where are the “Mind Change” equivalents of higher surface temperatures or CO2 emissions – the things we can measure and study?

So at the end of the third chapter, she attempts an extraordinary gambit. “Mind Change”, she insists, is not a hypothesis but a whole new paradigm. As a consequence, it cannot be tested like a conventional theory; those calling for her to produce evidence are missing the point. Greenfield’s idea is beyond the realms of “proof”.

“Absence of evidence is not evidence of absence,” she observes, “Thus it is impossible to demonstrate definitively that screen-based activities have no effect at all on the brain or behaviour, any more than I or anyone could prove definitively, to use an age-old example,” here it comes, “that there is not a teapot in orbit around Mars.”

So you can’t disprove the existence of Go… sorry, Mind Change, but surely you can provide some sort of evidence that it exists? “It is impossible to demonstrate just as conclusively that screen-based activities are having an unequivocal effect on the brain.” Why? “A flock of swallows rarely make a summer, and few single peer-reviewed papers … are viewed unanimously by all scientists as conclusive.”

This carries on over several pages that wouldn’t look out of place in a creationist pamphlet. She paints a picture of science filled with dogmatic old sods who refuse to accept new ideas. She invokes stories of brave mavericks like Nobel prizewinner Dr Barry Marshall, who gamely swallowed bacteria to prove they caused stomach ulcers, in defiance of conventional medical opinion at the time. Wisely, she steers clear of Galileo.

It’s clear how Greenfield sees herself and her place in science, but her examples are self-defeating. Marshall and his colleague, Dr J Robin Warren, made a clear prediction. They tested it, they presented the evidence, and minds were changed.

Why can’t Greenfield do the same?

How Facebook ruined the 80s

The table of contents provides one clue to the answer, covering a broad but erratic sweep of social networking, video gaming and web search. “One deliberate omission is the field of internet pornography,” Greenfield explains, “where the controversy and debate are obviously not so much about whether it is ‘good’ or ‘bad’ or about how it impacts on types of thinking, but more about legislation and regulation, which are outside the scope of the journey here.”

If that exception sounds a bit odd, what makes it downright astonishing is that in 2012 Greenfield backed a political campaign for default-on internet porn filters, citing the “vulnerability” of the developing brain. “If I had to choose between unfettered internet access, and having children potentially harmed psychologically or worse by porn sites, then for me the decision is an easy one,” she told the Mail.

Why the omission now? For that matter, why leave out the impacts of television, texting, the telephone, or other technologies that have radically altered our lives? What about electricity, the arrival of which completely transformed our sleeping and eating habits?

What’s never really explained is how the technologies that are included in her analysis are different from those that are excluded. Without that clarity, her story twists into irretrievable knots. Short videos on YouTube are presented as new, alien and risky because they erode attention spans; but short cartoons on television in the 1950s were part of a healthy and balanced upbringing because kids didn’t spend too long watching them.

To make matters worse, over time you detect the scope changing, expanding and contracting as needed to suit the arguments or evidence on a given page. “Technology is not necessarily being used in moderation,” the professor tells us at one point. “Entertainment media use in the United States among the young is, on average, more than 53 hours per week.”

Okay, but we’ve switched from video games and the internet to include television and “entertainment” more generally. It sounds pernickety, but it’s a huge problem. Throughout the book Greenfield insists that the change we’re seeing in the internet era is unprecedented, even compared to the emergence of electricity, telephone or, television; but her case studies keep collapsing because they fail to distinguish between the effects of “all of the above”.

For example, she points to a 90% reduction since 1970 in the ‘radius of activity for a child’, the area of the world they wander freely around in. This is a real and well-documented problem, but it’s not clear at all how this relates to video games, the Internet or social media websites, which wouldn’t appear for another 15, 25 or 35 years.

Are fewer children playing outside because of screens, or is it down to other factors: paranoid parenting, television, urban planning, or more parents driving their kids to school? It’s an interesting question, and the honest answer is probably that we don’t entirely know. Greenfield simply bulldozes her way though all that complexity, uninterested in alternatives. It’s just another another side effect of our screen-based lifestyle. Facebook’s clear and obvious impact on the children of the 1980s.

Which brings me back to the table of contents. The twenty chapters include sections of social media, video games, web surfing, and search engines. It’s exact;y what you’d expect from a book by Susan Greenfield, but wait a minute: isn’t this the wrong way round?

Most scientists set out to investigate a phenomenon. This thing is happening – why is that? On that basis you might expect to see chapters on shrinking attention spans, rising rates of depression, generational changes in empathy, and so on. Susan Greenfield’s investigation begins with a pre-conceived list of answers.

More selfish, or more screwed?

If new technologies are having a big impact on our society then it should be visible in certain population trends; the way we can detect the impact of smoking through cancer rates. Sure enough, trends become Greenfield’s favourite weapon in this book. She wields them like an overenthusiastic kid with their first hammer, battering away at the world with reckless abandon.

Take the decline in attention spans of schoolchildren, as Greenfield does. It’s fair to say that a lot of teachers agree with the professor and blame this on new technologies. The assumption is that kids are so over-stimulated by their diet of Grand Theft Auto, Snapchat and instant messaging, that sitting in a classroom with an adult droning at them all day seems slow and dreary in comparison.

That’s plausible, but then it’s also the case that kids aren’t getting as much exercise as they used to, and we know that lack of physical activity can affect performance on tasks requiring concentration. We know that teaching methods and standards will have changed in the same period. We know that IQ has been ticking upwards. There are many alternative explanations here and I’m not singling any out, but Greenfield seems singularly uninterested in exploring them.

Next up is empathy, which, we are told, is in decline. What researchers really mean by that is that kids answer a bunch of questions in a survey differently than their parents did 30 years ago. Data for previous generations doesn’t exist, so we can’t set this against any longer-term benchmark. Does it mean I’m part of a selfish generation? Do these measures have any real correlation to real world actions?

Greenfield quotes studies that show younger people volunteer less, but that’s not surprising when we have to work longer hours to pay higher university costs, and when buying a house is now beyond the reach of most young families. Are we more selfish, or are we just more screwed, facing the pressures of higher debt and lower standards of living than our parents?

Is more empathy even a good thing, as Paul Bloom asks in a fascinating essay? People with greater empathy are more likely to report asymmetrical relationships, and more prone to depression and anxiety. Women tend to score higher in tests of empathy, and this could easily set them at a disadvantage in the workplace.

None of these questions are even brought up, let alone tackled, and we’re left with more “ifs” than a Kipling poem. If the measure of empathy is accurate. If that translates into lack of kindness. If more empathy is always better. If the previous generation weren’t just an outlier. If this could somehow be linked to the rise of the internet rather than perhaps a change in parenting styles as researchers investigating the decline have suggested. If. If. If.

Apparently the kids can’t read either. “Already literacy standards are declining,” Greenfield asserts. “Research has shown that many children are more likely to own a mobile phone than a book. Another study … found that teenagers now prefer easier reads such as the Harry Potter and Twilight Series.”

Let’s set aside the million-plus words of the Harry Potter series for a moment. Greenfield’s statement is both vague and untrue. Literacy levels in England have been rising, not falling. It’s true that we’ve slipped behind other countries (22nd out of 24 countries in the developed world last year) but who leads the index? Japan – a country not entirely unfamiliar with video gaming. That valuable piece of context is conveniently omitted.

Of course as soon as the trends disagree with Greenfield’s assumptions, she finds reasons to ignore them. She notes for example that, “the violent crime rate is going down while the popularity of M-rated video games has increased.” But? “But then decreases in crime rate are most likely to be caused by a host of complex socio-economic factors.”

Oh so now it’s more complicated …

Whatever you want to see

At times, this greedy extrapolation goes beyond exaggeration to complete fiction. Research is present which simply doesn’t say what Greenfield claims it does. Take the following paragraph:

In a survey of US youth aged between 10 and 19, gamers spent 30% less time reading and 34% less time doing homework. Granted, it is hard to separate the chicken from the egg: perhaps children who perform more poorly at school are likely to spend more time playing games, which may give them a sense of mastery that eludes them in the classroom. We need to go beyond correlation to cause: but what we can’t do is just ignore the problem altogether.

Wait a minute, “perform poorly at school”? The study only recorded how long kids spent on various activities. It said absolutely nothing about academic performance and didn’t even attempt to investigate it, a fact the authors make crystal clear in their paper. “An important next step for future research will be to assess the ways in which video game play is related to academic and social outcomes.”

The survey was published in 2007. The following year one of the authors, Elizabeth Vandewater, actually took that next step in a review of research conducted up to that point. “Most studies find a small negative link between the total hours a child spends viewing TV and that child’s academic achievement. But when researchers take into account characteristics of the child, such as IQ or socioeconomic status, this link typically disappears.”

Earlier this year, PLoS One published a vast meta-study looking at data from 192,000 kids in 22 countries. Their conclusion? “Contrary to claims that increased video-gaming can impair academic performance, differences in academic performance were negligible across the relative frequencies of videogame use. Videogame use had little impact on adolescent academic achievement.”

Other studies may disagree, but my point here isn’t whether the conclusion is right or wrong, but that Greenfield is saying things about the research she cites that simply aren’t true. There’s no reason to assume that gamers who do their work faster do it less well – they may just be more motivated, more intelligent, or members of households that are higher on the socioeconomic ladder.

Then we have data taken completely out of context, like the literacy data earlier. “The culture of social networking may predispose users to a narcissistic mindset that in turn enforces low self-esteem,” she declares. “This in turn encourages the development of an exaggerated or completely different identity: the hoped-for, possible self.”

That might seem a bit extreme, but:

It is precisely what might now be happening. Kidscape, a British charity that helps prevent bullying and protects children, conducted a survey in which they assessed young people’s cyber lives through an online questionnaire. Of the 2,300 or so respondents … one in two say they lie about their personal details on the internet. Of those, the one in eight young people who speak to strangers online are the most likely not to tell the truth, with 60% lying about their age and 40% about their personal relationships.

Greenfield goes on to explain how this highlights “the fact that children often create a different persona when they interact with others, especially strangers, in a way that they wouldn’t in the real world.” Taken in isolation, all this sounds terrifyingly dystopian. But before we call the wahmbulance, let’s put this in context.

It turns out – and this may shock you so please, prepare yourself – teenagers lie. Research suggests that up to 98% of teenagers lie to their parents, and the other 2% were probably lying about whether they lie to their parents:

The teens lied about what they spent their allowances on, and whether they’d started dating, and what clothes they put on away from the house. They lied about what movie they went to, and whom they went with. They lied about alcohol and drug use, and they lied about whether they were hanging out with friends their parents disapproved of. They lied about how they spent their afternoons while their parents were at work. They lied about whether chaperones were in attendance at a party or whether they rode in cars driven by drunken teens.

In other words, and contrary to what Greenfield seems to believe, teenagers in the real world lie. They lie about personal details, they lie about their age, they lie about all the things they lie about online and they do it to your faces.

What does this all mean? I wouldn’t like to guess. I don’t know whether these statistics are indicative of some broader problem in society or not. What puzzles me is why Greenfield is so completely uninterested in finding out. Why she fails to ask any meaningful questions about almost any of the research she cites, to spend the 10 minutes it took me to find eg Vandewater’s follow-up today, or to critique and analyse what she covers in any substantial way.

It’s not that she’s necessarily wrong; it’s that she just doesn’t seem to care whether she’s right. All that seems to matter is that it can be twisted into the right shape to fit the preset list of answers she started the book with.

Of course I’m just as biased as Greenfield is, but that’s really my point: without good scholarship, if you cram together all these trends and charts and statistics you end up forming a kind of Rorschach test. You can find in those squiggly lines whatever you want to see.

Raindrops and Autism

In 2011, Greenfield was interviewed for New Scientist about what by now had become her pet subject. “You think that digital technology is having an impact on our brains,” asked the journalist Frank Swain, “So what evidence is there?” Greenfield’s response included the line, “There is an increase in people with autistic spectrum disorders.”

The comment sparked a storm of protest, with two main lines of criticism emerging. The first was scientific. One of Greenfield’s colleagues at Oxford, professor of developmental psychology Dorothy Bishop, took the step of writing an open letter pointing out Greenfield’s failure to grasp even the most basic facts about the topic:

A cause has to precede its effect. This test of causality fails in two regards. First, demographically – the rise in autism diagnoses occurred well before internet use became widespread. Second, in individuals: autism is typically evident by two years of age, long before children become avid users of Twitter or Facebook. You also seem unaware of the large literature discussing possible causes of the increase in autism diagnoses, most of which concludes that most, if not all, of the increase is down to changes in diagnostic criteria.

The second criticism was more visceral:

You may not realise just how much illogical garbage and ill-formed speculation parents of children with these conditions are exposed to. Over the years, they’ve been told that their children’s problems are caused by their cold style of interaction, inoculations, dental amalgams, faulty diets, allergies, drinking in pregnancy – the list is endless. Now we can add to this list internet use.

As Tom Madders of the National Autistic Society told the Guardian:

It’s very unhelpful … to have any suggestion that computers might have a harmful role when so many people with autism, and who are very socially isolated, find they can communicate through email and the internet.

Defending her comments, Greenfield issued a dismissive and bizarrely passive-aggressive remark that went on to spawn a Twitter meme: “I point to the increase in autism and I point to internet use. That’s all.”

In Mind Change she revisits the subject in – marginally – more detail. She back-pedals slightly, replacing “autism” with “autism-like trait”, but her writing suggests that Greenfield – who has no experience or expertise whatsoever in autism research – sees little meaningful difference between the two terms.

The studies that Greenfield puts forward here are utterly bewildering. One shows, according to Greenfield, that excessive internet use “has been associated with a lack of emotional intelligence.” The abstract of the paper describes this as a “weaker effect”, but more problematic is that the paper dates back to 2004 – before Facebook and Twitter even existed, online demographics were rather different to today, and a lot of students were still pretty new to the internet. Does the association suggest internet exposure causes a drop in emotional intelligence, or did the internet in its early days draw people with lower EI in the first place? Who knows. Who cares.

Another study examines the EEGs of people looking at faces, and concludes that “young” excessive internet users might be slightly slower. It’s speculative at best, and tells us pretty much nothing, but Greenfield performs a bait-and-switch, comparing the result to “infants who cannot track their mother’s face often become autistic”.

Then we head into the realms of the truly weird. Greenfield cites a pair of studies by researchers at Cornell exploring the relationship between TV viewing and autism diagnoses, and how in Greenfield’s words there might be “possible associations between technology use and the later development of autism.” The authors compared the amount of rainfall – rainfall – in various counties against cable TV subscriptions and autism rates.

Leaving aside the observation that TV seems to have crept back into the ever-changing scope of Greenfield’s book, there’s a pretty obvious explanation for these results. We already know that autism diagnoses are well correlated to socio-economic status – rich people are more likely to get their kids diagnosed. What else correlates with social demographics? Cable TV subscriptions. As for rainfall, well most of the richer states in the US aren’t in the dust bowl.

It’s hard to understand the kind of arrogance that would lead to a person with no expertise in the field drawing this kind of literature together to make broad statements about autism, and feeling so confident about it that they would be willing to spark stories about it in the national press. For most of the book, Greenfield’s sloppy scholarship is just irritating. On a topic as sensitive as autism, a subject already wracked with controversy in recent years, it crosses the line into something frankly unacceptable.

“Well, Twitter is part of the environment”

What about Greenfield’s own research? The “About the Author” blurb at the front of Mind Change informs us that, “She specialises in applying neuroscience to fundamental issues such as the impact of 21st-century technologies on the mind.” This is a whole book about that subject, so you would expect to see some of that work making an appearance.

This is something the Baroness has been challenged on in the past. Ben Goldacre has publicly questioned her unwillingness to publish on numerous occasions over the last four or five years, with no response:

If a scientist sidesteps their scientific peers, and chooses to take an apparently changeable, frightening, and technical scientific case directly to the public, then that is a deliberate decision, and one that can’t realistically go unnoticed. The lay public might find your case superficially appealing, but they may not be fully able to judge the merits of all your technical evidence.

I think these serious scientific concerns belong, at least once, in a clear scientific paper. I don’t see how this suggestion is inappropriate, or impudent, and in all seriousness, I can’t see an argument against it.

Mark Henderson, author of The Geek Manifesto, tackled Greenfield directly on the subject in a debate on Channel 4 News two years ago. “So far as I’m aware, and please do correct me if I’m wrong,” Mark offered, “you haven’t published anything in the academic literature on this, which is – as you know as a scientist – the proper forum for raising such concerns; and I’m very interested to know why you haven’t done that and whether you intend to?”

Greenfield replied, “If the argument is, as a neuroscientist, have I published on the impact of the environment on the brain” – it wasn’t – “then yes I have.”

“But on Twitter specifically?” Mark badgered.

“Well Twitter is part of the environment,” Greenfield responded, unconvincingly.

I’ve looked for relevant work, on her institution’s website and elsewhere, but I can’t find any. The only thing I can say for sure is that none of this work seems to have made it into her book.

Kids these days

Last year Greenfield had the opportunity to set out her ideas in fiction; a dystopian thriller set in the year 2121, which she called “2121”. The title was intended to draw comparisons with Orwell’s 1984 … and one suspects between Greenfield and Orwell.

Reviewing the novel for Vice magazine I described it, charitably I thought, as “a disease vector for stupidity.” She showed us a world in which generations of digital natives raised on video games and social networks were incapable of wisdom, social contact, and even sex. In fairness to Greenfield, she managed to produce one of the most erotic scenes ever written, which I described as follows:

Fred was already loosening the Helmet strap with the other hand that wasn’t angling my chin,” Sim begins. Asked by Fred to remove her “dress thing”, Sim then explains, “It was still stranger now to step outside of my garment. I only did so in the wash-waste, and never outside.” Then they have sex, at which point Fred realises that Sim may not actually know what sex is, which carries the awkward and tragically unexplored implication that Fred is actually a rapist. “Sim,” asks Fred, “do you know what we’ve just done?” “I think so. I think the Fact-Totum says it’s what people used to do before the reproduction programs made everything so much easier.

Once my erection had subsided, it was hard to get past the realisation that this is how Greenfield sees my generation. Once you peel away the scientific gloss, you end up with a laundry list of the sort of dismissive comments that middle-aged, middle-class curtain-twitchers have been making about “young people” for generations. Lazy, degenerate, selfish, good-for-nothing … the kind of comments that, applied to race, gender or ethnicity, would be considerably harder to defend.

It’s clear that Greenfield sees mind change as a particular threat to the young, but her entire understanding of “young people” is ambiguous and outdated. Just as the set of technologies she talks about changes from chapter-to-chapter; her definition of “young” never quite settles on a specific age group or cohort.

In a live-streamed lecture to the RSA yesterday I heard her suggest that today’s teenagers were the first “digital natives”, but that simply isn’t true. I turned 33 last week, and I was among the first generation of kids to get the internet as a teenager. Kids who were hitting puberty at the turn of the millennium are now pushing 30 and having kids of their own.

The Baroness tells us that: “The digital divide means that parents do not necessarily feel equipped to help their children.” That stereotype might have been true a decade ago, but in 2014 it’s utter nonsense. The latest cohort of parents grew up in the internet era – most of them are digital natives too, and well aware of the perils and pitfalls of cyberspace.

There’s a bigger problem looming for Greenfield here. In the same RSA lecture, she invoked this idea of “teens as the first digital natives” to suggest that mind change was a looming threat for the near future; but if the highly plastic brains of most people under 40-odd are already immersed in this new environment, the radical change should already be upon us. So where is it?

Coupled to that vague notion of “youth” is a proud ignorance of modern technology, and an open contempt for its users. In the same House of Lords debate we began with, she spoke of, “the baffling current preoccupation with posting an almost moment-by-moment, flood-of-consciousness account – I believe it is called Twitter – of your thoughts and activities, however banal.” In an interview with the Independent she said of Facebook: “I don’t have to go bungee-jumping to have an opinion on it.”

That ignorance regularly leaves her unstuck. On the topic of video games, Greenfield’s lack of comprehension and inability to distinguish between different genres of game causes her thesis to fall apart at the seams. Discussion veers between “games”, MMORPGs and “action games”. Considering her interest in social networks, it’s odd that the social and group aspects of multiplayer gaming are basically ignored. “Video games reward players for quickly modifying their behaviour when conflict is experienced,” she claims. It’s a nonsense statement that could only come from someone oblivious to the broad scope of gaming in 2014, when most recent hits rely on planning, cooperation and delayed gratification.

Of course, people like Greenfield don’t play video games. It’s almost impossible to separate Greenfield’s analysis of our society from the champagne-clutching position she holds within it. The “cultured” activities enjoyed by her peer group escape criticism. The TV she grew up with was fine, obviously. But the tweeting gamers who fail to conform to a middle-aged, middle-class ideal of the book-loving, theatre-going, London socialite are weird, wrong, pathological, immature.

“At a formal breakfast I attended recently where the main speaker was the British deputy prime minister, Nick Clegg, the woman sitting next to me was so busy tweeting that she was at a breakfast with Clegg that she wasn’t actually listening to what he was saying.” Well, maybe he wasn’t that interesting … but one suspects that the former director of the Royal Institution struggles with the idea that a man of such status shouldn’t be listened to.

It’s all weirdly counter-productive. The more Greenfield insists that the people she describes – invariably less fortunate than herself – are defective or antisocial, the more she appears so herself.

Do something …

With no central argument to hang it on, the flesh of Mind Change collapses into a sub-Gladwellian mash-up of hand-picked studies, just-so anecdotes and carefully interpreted statistics. There’s no sense of progress toward any conclusion, just a long gallop of facts and figures that leave the reader with the impression that, well, something must be wrong with all these damned screens about.

“It’s up to us to be proactive and to do something.” That’s Greenfield’s challenge, but there’s a catch. “For Mind Change there is no answer as such, because there is no clear question or goal.” Had this sentence been placed at the beginning of the book rather than the end, a lot of people would have been saved a lot of reading.

You can’t argue against Greenfield’s ideas because when you boil away all the conjecture, the unanswered questions, the innuendo, what’s left is … nothing much.

It’s not that the topic isn’t worth talking about. The world is changing, and our brains are adapting to that new world. Good analysis and research looking at the co-evolution of mind and society can only be a good thing. The problem is that Greenfield adds absolutely nothing to this debate. Her manuscript is a 384-page recital of the oft-mocked phrase common in scientific literature: “more research needed.”

Greenfield shows a complete lack of interest in both the research she cites and the technologies she critiques. Conclusions and positions are misrepresented, but often it seems less deliberate than lazy. She cherry-picks literature that appears to support her case but shows little indication of having read much of it, or asked the kinds of questions that leap from the page on even a casual reading. The professor displays one of the biggest character flaws a scientist can have: a lack of curiosity.

Then there’s the attitude, which stinks. Mind Change opens with a passive-aggressive misrepresentation of her own speech to the House of Lords. She insisted to New Scientist, “I didn’t say, and I’ve been misquoted universally, that [technology] rots the brain and it’s bad, I’ve never given value judgements, ever.” This from the person who spoke of “the damage that the gadget-filled pharmaceutically enhanced [world] is doing to our brains.”

She refuses to respond to or engage with critics like Dorothy Bishop or Ben Goldacre in any meaningful way. When the latter was due to participate in an event with her at the RSA yesterday, she demanded they drop him from the role of chair. When some of Goldacre’s criticisms were put to her, she replied (incorrectly): “He’s not a scientist, he’s a journalist.” Good science needs good criticism; but Greenfield has built herself an echo chamber.

But then this isn’t really science at all. Greenfield’s work is bog-standard social commentary disguised as neuroscience. She has witnessed profound changes in our society over the last 65 years, and she doesn’t like them. The kids of today aren’t polite enough, aren’t respectful enough, they’re spoilt brats and infants, they haven’t grown up properly like we did, they’re not as clever as us, they mock me on their weblogs. It was all much better in the fifties.

Once you peel away the scientific veneer, you find a series of statements that wouldn’t look out of place coming from a pub bore or a Richard Littlejohn column. And then you start to detect what makes her columns and speculations so infuriating to deal with. When Greenfield talks so casually about how broken we are, how inferior our minds, how decadent and unworthy our lifestyles and pursuits, it’s hard not to take it personally. I don’t believe that Greenfield represents a better generation of human being.

Nor is it wise for her to preach from such a precarious pulpit. Are we a generation of rude and lazy narcissists, lacking in mental fibre? Do we lack empathy and understanding toward others in our society? Are we sensationalists speaking in crude sound bites? Do we crave fleeting attention at the expense of meaningful achievement?

Physician, heal thyself.
