Another food for thought topic: getting into the minds of others.
Sort of covered this in the computer crime topic, but another thing came to mind today, so I thought I would give it its own heading.
I tend to use a decent amount of psychology in my work though it is more academic, conference oriented, inhouse questions, and technique development than active case.
Anytime I analyze a crime problem, I am expected to offer a solution to stop the problem and that usually means, so far anyhow, disabling the market the produces the crime. In order to disable the market, one has to understand what motivates individuals to participate in that market. Ie, it's sexy, exciting, and relatively harmless to steal antiquities because that's what movies like Topal and Entrapment show (nutshell). (but one is just a criminal and thief to do so).
Figure out what motivates them, see the world as they see it for that motivation, and even see themselves as they do. But really, it's just another way to approach and use forensic psychology.
Btw, how did I get into this? I probably started realizing that I had a flair for it when I was doing electronic warfare and started asking questions of why might an enemy commander launch his missiles down this or that axis. Ie, does he really know where we are ...... or is he launching a missile on the hope that if we are out that direction, that we will give ourselves away with the noise when we start defending ourselves?
