How smiling changes a man’s apparent masculinity.
Smiling makes men more attractive to women looking for long-term relationships, research finds.
But smiling does not make men look more attractive to women looking for a short-term relationship, as they appear less masculine.
The results come from two experiments in which hundreds of women evaluated pictures of men — some of whom were smiling.
The study’s authors explain:
“Smiling enhanced the male attractiveness for long-term relationships but not for short-term relationships.
The facilitative effect of smiling on the long-term partners was observed for East Asian as well as for European participants.
In addition, smiling faces were rated to be less masculine and more trustworthy and mature than neutral faces.”

So, smiling makes a man’s face look less masculine, but also more trustworthy.
The study’s authors analyse this in terms of evolutionary psychology.
This is the theory that many of our traits have evolved over the millennia to help the race reproduce.
In other words, at some level, some of the things we do when selecting partners (and other things) are so because our genes have programmed us that way.
Evolutionary psychology suggests two types of mating strategies have evolved.
In the long-term strategy, women are ‘programmed’ to look for someone who will help raise the children.
For that you need someone trustworthy — in other words a man who smiles (among other things, of course!).
The short-term strategy cares less about trustworthiness and more about the genes.
More attractive and masculine men have better genes in this context, so the lack of a smile makes them look like a better bet for a short-term relationship.
As the authors explain it:
“…social and cooperative characteristics would be primarily important for long-term partners but not very much for short-term partners because long-term cooperation is necessary for parenting in the former but not in the latter.
Women put more emphasis on social factors such as trustworthiness for the long-term relationship, where paternal investment is expected, in order to minimize the risk of losing commitment from their partner during pregnancy and parenting.”
The study was published in the journal Evolutionary Psychology (Okubo et al., 2018).
