It’s an ugly day for voter rationality in today’s New York Times. According to a new study by several political scientists, our political predispositions may be genetic (and last summer’s Zellout may have been the result of a lingering discordance between genetic and environmental factors in Miller’s make-up.) Whatsmore, we seem to choose our elected leaders immediately by their physical attributes, namely a general look of competence: “Both babies and baby-faced adults share certain characteristics: round faces, large eyes, small noses, high foreheads, and small chins. No one trusts the competence of a baby, and few, apparently, trust that of an adult who looks like one.” (Don’t lose heart, fellow advocates of an informed and capable electorate — There’s obviously a huge gaping hole in this latter theory.)
