In the group that performed poorly on the cognitive reflection test, only 40% of men and 25% of women said they would take a 15% chance of $1,000,000 over a sure $500. In the high-scoring group, 80% of men and 38% of women said they would take the 15% chance of a million dollars.

In a comparison of a 100% chance of $1,000 and a 90% chance of $5,000, only 59% of men and 46% of women in the low-CRT group, and 81% of men and 59% of women in the high-CRT group, said they would take the risky option.
