and then dividing them into several categories:

Traits that are indeed actively attractive to women, or some subset thereof.

Traits that are neutral per se, but have a positive correlation with others that are attractive, or negative correlation with others that are unattractive.

Traits that are unattractive, but easily overshadowed by other less obvious (or less mentionable) traits, which produces striking but misleading examples where it looks like the "jerk" traits are in fact the attractive ones.

Here's a couple more:

• Traits that are neutral or unattractive, but help people in their mating interaction during one-on-one interaction with a potential partner (e.g. initiation or receptiveness).

• Traits that are neutral or unattractive, but help people compete with others of their same gender

In sexual selection, there is a difference between intersexual choice, and intrasexual competition. "Women go for jerks" or "nice guys finish last" might not be a primarily a claim about the traits that women are attracted to; rather, it could be a claim about the traits necessary to initiate with women and compete with other men. All this stuff partially overlaps, but there are differences.

For example, pushing past competition on a crowded dance floor, dealing with competitors interrupting you, or making a physical advance on a potential mate may require a slightly different balance of traits (e.g. more assertiveness or even aggression) than what is necessary to attract mates.

Specifically, I would suggest that the male initiator script along with male-male competition jacks up the necessary amount of "jerk" traits beyond what women are actually attracted to. This hypothesis could help explain why people have trouble seeing eye-to-eye on this issue.
