Danger and Creativity

Mueller et al demonstrate in a couple of experiments that

People often reject creative ideas, even when espousing creativity as a desired goal.

This makes sense.  According to Read Montague, brain scans of our reactions to familiar things have the same signal as when we react to actually good things. In a risky environment this seems powerfully adaptive to me. On the other hand, a capacity take unnecessary risks indicates a biological surplus so should be a plus in the sexual selection stakes provided it doesn't happen to kill you.

For example, this lad is demonstrating a biological surplus.  Of course, he may not describe it like that.  

Sex and personality, methodological error alert

In conclusion, we believe we made it clear that the true extent of sex differences in human personality has been consistently underestimated [due to deficient methodologies and sloppy statistics.]

The primary problem is a poor multivariate distance measure.
