As Emily Esfahani Smith reported in the Atlantic, the results of the "bids" are staggering: in one of Gottman's studies of marriage, couples who divorced after six years had the "turn toward" reply 33% of the time, and the couples that were still together had the "turn toward" 87% of the time. Andrews psychologist David Perrett and his colleagues found that some people are attracted to folks with the same hair and eye color of their opposite-sex parents, as well as the age range they saw at birth.

"We found that women born to 'old' parents (over 30) were less impressed by youth, and more attracted to age cues in male faces than women with 'young' parents (under 30)," the authors wrote.

Results showed that men rated women most attractive when they looked happy and least attractive when they displayed pride.

Women, on the other hand, rated men most attractive when they displayed pride and least attractive when they looked happy.

Dean Cortez is an American, and his profession is art and dating.

In one 2011 study, researchers found that both men and women rated opposite-sex faces more attractive when they closely resembled their current or most recent partners. Literally — fill up the physical space around you with hand gestures and an expansive posture.

Men, however, were less attracted to faces that looked similar to their current partner than women were. In one 2016 study, researchers observed men and women in speed-dating sessions.

But these findings only applied in certain situations.

Specifically, the men had to feel "committed" to the woman, which in this study meant that they'd chosen her as their partner, instead of being assigned to her.

Sure enough, people were selected more often when they were pictured in expansive postures.
