Is a predisposition toward certain behaviors or occupations part of nature or nurture? That’s a question still being debated by social and behavioral scientists. This week’s cartoon, from the July 1955 issue of ACerS Bulletin, provides the answer courtesy of one suburban Mom. Here’s another theory: it’s late July, still a month a so before school…
