So does anyone have any good theories or studies that show why people are set off by some things? Look at the threads on this forum and you'll notice what i mean. Things like abortion or the 1st amendment or the death penalty will send pages into double digits in a day or so. Then you have things that dont gain much attention. Stuff like international economics, video game consoles, the judicial system, social security (up until recently), or welfare dont seem to get much attention. Is there common associations between set A that arent in set B that set people off? Are we influenced by the media about what to talk about?
