Almost all face blind people use hair styles to tell people apart, and generally, the longer the hair is, the better. For this reason, serious consideration should also be given to dropping any policy that encourages students to keep their hair short. Few children can muster the personal resources alone to take on this problem, and for a face blind child who may be socially backward, taking on such a problem is doubly hard. This is one area that parental assistance is essential, to assure that the child gets an environment where he can develop socially. At Play Entertainment Actors, and those who work with them, are another group that have high facial skills.
Many actors do look alike.
This makes it more difficult for face blind people to follow the plots of movies, TV shows, and plays than it would be if characters looked less alike and more like a random sampling of the general population. Occasionally I've encountered a movie or TV series where the people don't all look alike. The writers of these shows for some reason are not driven to make everyone look alike the way most writers are. Needless to say, those shows have become my favorites. Of course, what one does for recreation is mostly a personal choice, as is the clothing he wears when participating.
