Evidence

And who are the counterarguers? They are the politically involved: those who claimed to follow public affairs closely, who reported a higher level of political activity, and who possessed more political knowledge. Of these three factors, political knowledge appeared to be the most consequential. In a regression analysis, pooling across the experimental groups, counterarguing was strongly predicted only by political knowledge (Beta=.43, p<.05). — John T.
