most of them can't. they actively vote against their own interests and everybody else around them. if you confront them with facts and figures, they ignore it and resort to emotional appeals.

just because you can find one child that can play chess at age 4 doesn't mean that the rest won't just eat the pieces and shit on the board.

Have you seen actual four year olds? Most would not only make illegal moves, they will also throw a few pieces away, place their favorite giraffe next to the "horse," and laugh at your frustration. Thus proving, once and for all, that four year olds are not in fact intelligent. /s
