A recent study suggests that leaning right might, well, make you lean right. I don’t see a copy of the study online, but here’s the abstract:
A prominent metaphor in American politics associates left with liberals and right with conservatives. Three studies investigate the extent to which this metaphor not only shapes how people talk about politics, but how people think about politics. Participants who are oriented to their right report more conservative political attitudes, while those who are oriented toward their left report more liberal attitudes. This supports the notion that spatial metaphor is a key ingredient underlying abstract thinking even for important belief systems.
