When working with electronics, I use the CS vs EE analogy.

CS person: grabs part by hand, shuffles across the floor in socks, brushes dust off a pin, presses part into place

EE person: stares in horror, a grounding strap dangling from their hand

CS: "What?"

EE: "You know you're supposed to ground yourself to prevent static discharge from frying parts?"

CS: "Bah, it worked fine the last time I did it this way."

Point being there's a difference between something that works 99/100 times, and something that works 60/100 times. And when failure means a dead part, probably best to go the extra mile.
