Ever notice how often couples look a little like one another? Or they have certain “features” (in terms of looks) in common? One possible theory is that people get used to their own looks, and consider themselves “good looking”, then when they recognize their own features in someone else, that person is good looking to them.
So now, my question: was this less the case before people had mirrors and cameras? When people did not see themselves often, did couples not look so much “alike”?
