===The puzzlefallacy===

The paradox arises when a single variable is improperly equated across two different initial conditions that are not equal. In this case, ''A'' represents an expected value being improperly scaled depending on the selected envelope.<ref name=":5" />

The puzzle is to find the flaw in the line of reasoning in the switching argument. This includes determining exactly ''why'' and under ''what conditions'' that step is not correct, to be sure not to make this mistake in a situation where the misstep may not be so obvious. In short, the problem is to solve the paradox. The puzzle is ''not'' solved by finding another way to calculate the probabilities that does not lead to a contradiction.
