Experimental psychologists primarily do research (mostly in labs). My first graduate degree was in exp psyc and I spent most of my time at NIH studying neural pathways that mediate anxiety. Gave a lot of rats a lot of benzodiazepines such as alprazolam (Xanax) and then competively blocked various neural pathways to determine which one transported the drug to get an anxiolytic effect. A wordy response but it gives you an idea of what that field does. My second grad degree is in counseling and I am primarily interested in abnormal behavior.

Most of the time, anyone willing to kill or harm a large group of people likely has antisocial personality disorderr (sociopath) but some folks are just zealots and feel that God is calling them (odd behavior for a God - but that's my point of view). Anway, these folks are incapable of empathy, have no moral compass, and no sense of right or wrong and some report that they only time they feel anything at all is when they are harming someone else (check YouTube for "The Ice Man").

Anyway, I do enjoy following the conversation and I am learning a lot. When this story first broke I figured I would find some pilots rather than listen to talking heads discuss such low probability events such as a black hole eating a jet (if a jet is on the event horizon for a black hole I gotta believe the rest of the planet is likely as well).

Thanks and take care,
