They do act like this. You can pretty much fit into the zone that loosely defines "normal" and have a highly skewed perception.
There are perfectly "normal" people who go to work, pay their taxes, observe most of the laws (I am excluding traffic laws because the idea that one must follow them is very flexible in most of our minds and dependent on things like whether or not we are in a hurry or are being mindfully observant), and yet they have perspectives that aren't making them happy at all because their perception is so skewed, and yet they do nothing that is likely to correct it (because it is "normal" for them), or they impulsivly do things to try to correct it that just aren't likely to work out very well.
