Helena Cronin on four Ts

John Brockman's asks a new annual question,
What have you changed your mind about? Why?
Among 163 answers, I choose one by Helena Cronin, a philosopher from the London School of Economics.

She used to think that three Ts, namely talents, tastes, and temperaments, are enough to explain why men are at the top, especially if you add some bias etc.

She no longer think so. You must add another T that is arguably the most important one, namely the tails. This word really means the variance but variance doesn't begin with T. ;-)

She is remarkably quantitative about the effect of the second moments on the distributions. She might be a reader of La Griffe du Lion if she's not La Griffe du Lion himself ;-) which is unlikely but possible!
