It is a big question whether or not a primitive statistical methods are applicable to such vastly complex system as brain, given that no one could trace the causes of this or that manifested behavior, any other way but popular Freudian memes.
That doesn't take away from the fact that they had the creativity to think of it, did it, and added to our collective knowledge as a result. Sure, the results seem obvious in retrospect, and the process doesn't seem too tough to put together. But I'm grateful for their work nonetheless.
1) The fact that they based the outcome on giving up seat for someone. They could as well give them a gun and see who is willing to shoot someone. it has NOTHING to do with meditation.
