Cause & Effect

Determining cause and effect is one part finding the cause and one part convincing people of said cause. Effects can be argued about too, but causes can always arguable. That is, at least, if the effect has already come to pass. The effect is usually apparent in hindsight, but it can match with an endless number of potential causes. For example, the evolution debate has been going on for centuries but may never be resolved because no proposed cause will satisfy everyone. It doesn't matter which proposed cause is correct.
