This is getting deep into Dark Arts territory, and according to Predictably Irrational, the opportunity to use these powers for evil has not gone unexploited.

I'm a little worried that calling (a/i)rrational persuasive techniques "Dark Arts", even in seemingly indefensible (though, it must be said, minor) cases like this, biases us against them and will make people averse to using them even when doing so is ethical and beneficial. What do others think? Am I overreacting?
