I've heard of that before, but it always made me wonder - are we just supposed to accept unquestioningly that powdered eggs are indistinguishable from fresh? Sure, there's no question you can make something edible with dehydrated eggs, but that isn't proof there's absolutely no difference.

In general, the existence of a bias is insufficient proof that you should reverse your conclusion.

Nice - I hadn't come across that. Spot on.
