It's interesting that you posit reasons (irrationality, unreasonableness) for the choices that people make.Depends on your purpose. CARM is overrun with completely irrational people. You can't reason with an unreasonable person. It is completely pointless. Yet people keep trying to reason with unreasonable people. Complete insanity. You may as well be a rabid dog chasing your own tail. Many examples on this very board every single day.
