Gelast

Even if we grant that the "gelasts" are getting reduced to the dimensions of a petty sect, the consideration need not deter us from choosing laughter as our theme.

The phenomena presented by the misogelast, or laughter-hater; the agelast, or non-laugher; the gelast, who is the laugher himself, and the hypergelast, who is the laugher gone intemperate, are looked into, and as far as possible accounted for, by Dr. Sully.

So it might well be the other way round; not the agelast or misolgeast is "somewhat insensitive" to the ways of his fellows but the gelast or hypergelast.

A personality profjle of the gelast or agelast has not so far been convincingly established, nor has a pattern of humor been consistently demonstrated in individuals with different personality types.
