Don't just ask why. Ask why until you know you've found the root cause.

Searching for "the" root cause (as opposed to more than one) is its own fallacy though.


The Ishikawa diagram (http://en.wikipedia.org/wiki/Ishikawa_diagram) is a way of assuming and charting out multiple causes.


So the root cause of the problem "why can't we play outside?" is because "god is dead and we're alone".
