Evolutionary Psychology

A recent study reveals that openness to casual sex is linked to lower self-esteem and weaker moral views in women. For men, however, this sexual behavior is largely unrelated to their self-worth.

Why do women regret one-night stands more than men? A new study reveals this gap only exists in heterosexual encounters, and it is largely driven by a lack of sexual satisfaction and orgasms for women.

New research shows that Chinese parents and adult children often share similar preferences for a future spouse. The study suggests that these shared values, particularly regarding financial stability, are strongly tied to specific childhood parenting styles.

A new study reveals that women experience greater romantic jealousy when a potential rival has highly feminine facial features. While this effect occurs in both heterosexual and lesbian women, it is significantly stronger among straight women.

Charles Darwin suspected that humans and animals share similar aesthetic tastes. A new citizen science experiment supports this hypothesis, showing that people strongly prefer the exact same acoustic patterns that attract female animals.

A massive new analysis of over 200,000 people reveals that the relative lengths of your index and ring fingers are linked to your sexual orientation, pointing to the powerful role of prenatal hormones in human development.

A new study of German twins suggests that the strong connection between a young adult's cognitive ability and their future socioeconomic status is largely driven by their genes, rather than shared family environments or random life events.

From internet slang to science: understanding the psychology of sapiosexuality.

When choosing a partner, do you value wealth or kindness? A new study finds that while humans have a default preference for generosity, our priorities quickly shift toward wealth if we find ourselves in a highly unequal environment.

A recent study reveals that people who are highly open to new experiences tend to have fewer children. Scientists attribute this to delayed parenthood, shorter romantic relationships, and a lower overall drive to start a family.

You aren't imagining it—your own brand smells better. Here is the evolutionary psychology behind the phenomenon.

Despite their small numbers, incels loom incredibly large in public consciousness. A new study explains why: their stories hit our deepest evolutionary panic buttons regarding sex, status, and societal threat.

A study finds that adolescent boys increasingly mistake friendliness for sexual interest as they mature. But teenage girls rarely have their romantic advances dismissed as mere friendliness.

Critics have long dismissed evolutionary psychology as “just-so stories.” A new conceptual review challenges this view, arguing the field generates rigorous, falsifiable predictions—some of which have been decisively overturned.

Why do some find kissing more arousing than others? New data suggests that those who frequently imagine intimate scenarios are more likely to rely on kissing as a catalyst.
