A big part of my educational/professional background involves understanding human social behavior - online and offline. Among the head-butting going on around here lately, I've noticed an underlying issue and I thought some people might be interesting in this little tidbit of information that could explain a part of it.
There's a psychological concept referred to as a person's "locus of control" and it has a huge impact on who butts heads with whom, especially on sites like this. A person's locus of control is basically their view of how/why life takes the twists and turns that it does, and how much control we have over those things.
The locus of control runs along a continuum, but has two distinct ends: the external locus of control and the internal locus of control.
People who have an external locus of control tend to believe that things happen or come to them because some outside force controls those things, whether that's fate, karma, destiny, God, your boss, mother, state governor, etc. For people with an external locus of control, they lean toward the idea that it doesn't matter much what they do because outside forces control the outcome anyway.
People who have an internal locus of control believe they have a significant influence over things that happen to them. These people tend to be more action oriented in just about every area of life. They don't believe as much in luck as in planning and they tend to believe the outcome of any situation directly reflects their efforts and behaviors. They seek information and knowledge, so they can make the most appropriate decisions in every arena of their life. They also tend to take more responsibility for their personal situations - both positive and negative.
The thing about these two categories of people is that when you get a large group of people together, those who fall strongly on one end or the other tend to irritate the crap out of each other.
If you're curious about where you fall on the scale, there's a little online test available through the UNCC website: http://www.psych.uncc.edu/pagoolka/LocusofControl-intro.html
Obviously it's not as simplistic as just taking a 13 question test to define who you are in the deepest recesses of your personality, but that quicky test can give you an idea of where you fall on that particular scale and might offer a little bit of insight to why some heads are butting with some other heads so much lately.
I think it's pretty obvious with me, but just in case it's not.. I have a very strong internal locus of control.
