Why Agile Minds Deploy Both Rational and Intuitive Problem-Solving

A rare aha moment in 2011 set me chasing new problem-solving research. The study Rational Versus Intuitive Problem-Solving: How Thinking ‘Off the Beaten Path’ Can Stimulate Creativity published in Psychology of Aesthetics, Creativity, and the Arts stung me out of a spot of intellectual arrogance. From my perspective, John Dewey’s 19th century step-wise Read the rest of this entry »

Daniel Kahneman on the Need to Think Slow (at times)

So Much for Snap Decisions (The Wall Street Journal):
– “How is it that so many people make decisions that, from their perspective, seem so right—and turn out so wrong? Blame it, in part, on thinking “fast.”

– “On some occasions, when the stakes are high, examining the evidence more systematically—especially the evidence that makes you uncomfortable—is likely to be worthwhile.”

– “This is how scientists often operate in evaluating their own ideas. They imagine a severe reviewer who will be searching for weaknesses in their argument.”

How cognitive illusions blind us to reason (The Guardian):

Why do Wall Street traders have such faith in their powers of prediction, when their success is largely down to chance? Daniel Kahneman explains.

– “Looking back, the most striking part of the story is that our knowledge of the general rule that we could not predict had no effect on our confidence in individual cases. We were reluctant to infer the particular from the general. Subjective confidence in a judgment is not a reasoned evaluation of the probability that this judgment is correct. Confidence is a feeling, which reflects the coherence of the information and the cognitive ease of processing it. It is wise to take admissions of uncertainty seriously, but declarations of high confidence mainly tell you that an individual has constructed a coherent story in his mind, not necessarily that the story is true.” …

– “The subjective experience of traders is that they are making sensible educated guesses in a situation of great uncertainty. In highly efficient markets, however, educated guesses are no more accurate than blind guesses.”

Mind Teaser: Consider Linda

(I hope you enjoy this very revealing mind teaser!)

Please consider Linda, a 31-year-old woman, single and bright. When she was a student, both in high school and college, she was deeply concerned with discrimination and social justice, and also participated in anti-nuclear protests.

Which is more probable about Linda’s occupation today? (a) Linda is a bank teller; (b) Linda is a bank teller and active in the environmental movement.

Quick, what’s your answer? (a) or (b)?

If you answered (b), you are wrong, and in good company. That’s what most of my colleagues and I answered the first time we saw this teaser in one of our Stanford Organizational Behavior classes.

It is more probable that Linda is a bank teller, which is a whole category, that she is both a bank teller AND also active in the environmental movement, which is a subset of that whole category.

A recent Wall Street Journal article explains the phenomenon:

Free to Choose, But Often Wrong:

“When psychologists Daniel Kahneman and the late Amos Tversky conducted an experimental survey in the early 1980s asking people to answer this simple question, they discovered, to their surprise, that most respondents picked “b,” even though this was the narrower choice and hence the less likely one. It seems that saliency in this case, Linda’s passionate political profile trumps logic.”
