Well, that was sort of tongue-in-cheek, because I'm one of them sciency types myself, and I do definitely obsess about causality. Drives me nuts when people use "because" for the vaguest of logical inferences.
"Because" starts in elementary school. It's the third most common answer students give. The most common is a shrug of the shoulders, followed by "I don't know."
For many students these three answers are all that is needed for effective communication at home.
