Re. the linked article about the cognitive confusion test:

80 percent of high-scoring men would pick a 15 percent chance of $1 million over a sure $500, compared with only 38 percent of high-scoring women, 40 percent of low-scoring men and 25 percent of low-scoring women.

Wow. That's the most mind-blowing thing I've read in a while. I can't think of a good explanation for anyone picking the $500, let alone the male-female difference. Maybe they assume that someone might actually give them $500, but the $1M is a scam. And how does this square with the idea that poor people play the lottery more?

Princeton students scored a mean of 1.63. Heh.

Say, you're starving and if you don't get a meal today, you'll die. In such situations, the choice between 15% chance of $1 million and a sure $500 boils down to a choice between 15% chance to survive today and a 100% chance to survive today (assuming that the meal costs less than $500.)

Perhaps the people who chose $500 operate in this 'starvation mode' by default.

The general term for "people who operate in starvation mode" is "the poor".

I doubt this is the case for most of the people who would take the $500 - I'd assume it's more that most of them couldn't or just didn't think to calculate the expectation value of a 15% chance at a million.

I think people are flipping the offer in their minds and comparing a sure $500 to an 85% chance of zilch.
