The reason I'm arguing this is because "under certain conditions" gets dropped with repetition and pretty soon people think hot water freezes faster than cold water as a matter of course. It becomes one of those things that "everyone knows" that isn't true.
It's actually a common enough effect that no one really cares about except as an interesting science problem.
