I've been fine-tuning my jerk-detector later. One thing that has always puzzled me is the nature of jerks/arseholes. Why do they act the way they do? What causes them to be so mean, subtly or otherwise. There seems to be a realatively close percentage in every group of people. While some groups might be rougher around the edges than others, the percentage of inherrant jerks seems to be around the same, taking up maybe 5-15% of the population in the given environment. Now here's my question. Are jerks born jerks, or is it something they aquire from their background? Most would probably tell you that it's totally a background-related issue, and that's what I've always thought, but I'm starting to wonder if it isn't more inherrant. The certainty that there will be that certain percent makes me think this. I see roughly the same percent of jerks in every environment/group I see. Sometimes in a more mature environment the jerkyness can seem to dissapear, but it will be there under the surface, and will strike in an often very subtle way. What do you guys think about this?
