Human beings like regularity and predictability. Change is bad. Consider the existence of a hunter-gatherer living life in the wild: every change in the weather, every change in the environment, every new sound in the night, new people, new animals—every one represents a potentially mortal threat.
There are no longer saber-toothed tigers in my town, but we still prefer that things remain constant and stable. We’ve learned the right responses to feel adequate to the challenge. We know how to gauge our efforts, and we don’t need to work too hard to get a level of acceptable results. And we can make reliable predictions about the future, which makes us feel safe and secure. The weird part is that we can feel the most comfortable when unknowingly, we are in the most danger.
