Study tests the good genes ovulation shift hypothesis, which states women's preferences for certain male behaviors differ throughout their ovulation cycle. Researchers found no evidence that a woman's preference changes across the ovulation cycle. However, women tend to perceive men as slightly more attractive when fertile than during other cycle phases.
A new study in Body Image reports women who evaluated as less attractive were more motivated to diet and be thin if they had a husband considered more attractive. The additional motivation to be thin was not apparent in women considered to be more attractive that their partner. In men, the motivation to diet was low, regardless of their own, or their wives' level of attractiveness.
According to researchers, children believe the less attractive you are, the less trustworthy you are.
