Common sense is no replacement for science; plenty of "everyone knows" knowledge has had its legs cut out from under it by a well-designed study. Nevertheless, some research turns up results that don't exactly shock and awe.
Such no-duh research usually has a serious underlying purpose, from the study of why people cheat to the roots of racism. Researchers have to understand the basics of everyday phenomena in order to understand them, after all.
