What is cause and effect? How can you tell if one thing causes another? Why do people get confused about what causes what? Why do some people say racism causes niggers to be stupid when obviously it's their DNA?
This is actually an important topic for politics, since one of the main things people disagree on in politics is what causes what.
So if we could get clear on how to determine cause, and how to avoid reaching false causal conclusions, it would go a long way toward clearing up some points of contention.
