Why are people often so predictable?

I agree with that. But, to give justice to your question, lets take it a bit further. We, each one of us, is shaped by that which we can comprehend most readily. The shit we don't comprehend? It's off-putting. Could even be scary. Often times comfort is the balancing weight against comprehension on the scales of history. Which way will the lever... lever. I apologize, I understand my jokes are dumb but I cannot stop myself for the life of... me. Anyway, We are systems under constraint. What we can do is derived from that certain balance. Right, well now I sound like Carl Jung and that is heresy. I'll see myself out.
