The actual story differentiates between "short term" partners (think 1 night stands, hookups) vs "long term" mate (think husband / wife / long term boyfriend / girlfriend ). I understood it to say that Jerks / Bad Boys / Narcissists also have a lot of sexual partners, but only for a short period, whereas the "Nice Guys" / Atruistic people have more sexual partners also, but for a longer term / time frame. Did I interpret this incorrectly? If not, a more apt title is "Altruistic People Have More Long Term Sexual Partners"
