reflects and reinforces this mating choice. If the society around him endorses casual sex, he will have a negative reaction to this culture as it threatens the stability of his mating model. People in monogamous relationship not only discourage casual sex, but also attitudes and beliefs that accompany this mating strategy, like recreational drug use, abortion, and no-fault divorce.
The study surveyed 987 participants who were asked to identify themselves as liberals or conservatives, religious or not, and were made to take sides on political issues. They answered questions about their personalities, sensitivities, and moral views. They also discussed attitudes and moral stances on sex and recreational drugs.
Researchers found they could predict a person's views on drug use by just asking a few questions about casual sex, like "Is sex without love okay?" Contrary to traditional causal models, once you know about someones attitudes toward casual sex, you don't learn much more by finding out about their religion, politics, or personality.
This supports the idea that one's sexual and reproductive strategies are essential in determining their religion, politics, and personality. Your choice of a relationship type shapes your world view in order to reinforce your mating strategy. Moral beliefs don't so much inspire you to do the right thing as they attempt to control and justify your behavioral choices and reproductive model.
