This habit of linking obnoxious behavior or stupidity of decisions to personal "stupidity" of the agent is one hell of a bad habit. Joanna's claim above is _stupid_, but we certainly know that Joanna is not stupid. The implicit premise is that all 6 plus billion humans have identical goals. When you allow for wildly different purposes, the ascription of "stupidity" disappears. We don't accurse an arsonist of being stupid in playing with matches.
