"Big thick beards are back with an absolute vengeance and so we thought underlying this fashion, one of the dynamics that might be important is this idea of negative frequency dependence," said Prof Rob Brooks, one of the study's authors.
"The idea is that perhaps people start copying the George Clooneys and the Joaquin Phoenixs and start wearing those beards, but then when more and more people get onto the bandwagon the value of being on the bandwagon diminishes, so that might be why we've hit 'peak beard'."
Beard trend is 'guided by evolution' by James Morgan
Explain to me, please, what "to hit 'peak beard" means.
It means that the writer thinks we have reached the point where the most people having a beard has happened. Beard-wearing is at its maximum. Let's say that 40% of the population of the planet have a beard. In the writer's opinion, there will never be a point where more than 40% of the population of the planet have a beard.
