Do you take one box or two boxes?

In My Humble Opinion

Economy of scale I think makes a difference here. Think about the scenario like this:

  1. The open box has a dollar in it. The mystery box has either nothing or $1000 in it.
  2. The open box has a million in it and the mystery box is either empty or has a billion in it. (This scenario would make me a two-boxer)
