Read the whole post.The Limits of Self-Knowledge
Posted on: October 12, 2009 11:57 AM, by Jonah Lehrer
Over at the BPS Research Digest, a number of researchers respond to a very interesting question: "What's one nagging thing you still don't understand about yourself?" All of the replies are intriguing, but my favorites answers concerned the limitations of self-knowledge. Here, for instance, is David Buss:
One nagging thing that I still don't understand about myself is why I often succumb to well-documented psychological biases, even though I'm acutely aware of these biases. One example is my failure at affective forecasting, such as believing that I will be happy for a long time after some accomplishment (e.g. publishing a new book), when in fact the happiness dissipates more quickly than anticipated. Another is succumbing to the male sexual overperception bias, misperceiving a woman's friendliness as sexual interest. A third is undue optimism about how quickly I can complete work projects, despite many years of experience in underestimating the time actually required. One would think that explicit knowledge of these well-documented psychological biases and years of experience with them would allow a person to cognitively override the biases. But they don't.And it's not just psychologists who experience the limitations of self-knowledge. Just consider Harry Markowitz, a Nobel Prize winning economist who practically invented the field of investment portfolio theory. In the early 1950's, while working at the RAND Corporation, Markowitz became intrigued by a practical financial problem: how much of his savings should he invest in the stock market? Markowitz's breakthrough was to derive a complicated mathematical equation that could calculate the optimal mix of assets. He had come up with a rational solution to the old problem of risk versus reward.

One nagging thing you still don't understand about yourself
The email edition of the British Psychological Society's Research Digest has reached the milestone of its 150th issue. That's over 900 quality, peer-reviewed psychology journal articles digested since 2003. To mark the occasion, the Digest editor has invited some of the world's leading psychologists to look inwards and share, in 150 words, one nagging thing they still don't understand about themselves. Their responses are by turns candid, witty and thought-provoking. Here's what they had to say:
Susan Blackmore: Consciousness
Paul Broks: What should I do?
David Buss: Overcoming irrationality
Robert Cialdini: Over-commitment
Marilyn Davidson: Lost opportunities
Elizabeth Loftus: Nightmares
Paul Ekman: Death and forgiveness
Sue Gardner: Dark places
Alison Gopnik: Parenthood
Jerome Kagan: Methodological flaws
Stephen Kosslyn: Satiators and addicts
Ellen Langer: Optimism
David Lavallee: Sporting rituals
Chris McManus: Beauty
Robert Plomin: Nature, nurture
Mike Posner: Learning difficulties
Stephen Reicher: Who am I?
Steven Rose: The explanatory gap
Paul Rozin: Time management
Norbert Schwarz: Incidental feelings
Martin Seligman: Self-control
Robert Sternberg: Career masochism
Richard Wiseman: Wit
I'd like to extend my sincere thanks to the contributors for baring their psyches and sacrificing their time. Thanks also to The Independent for helping spread the word. Here's to the next 150 issues of the Research Digest!
