Why do you hate so large part of humanity?

Lots of people can be extremely bright, but prefer to work in a supermarket or similar. Never, ever, make assumptions about who is bright, and who isn't. There is this alternative spelling ass-u-me. It very clearly indicates the result of assumptions. It makes an ass out of you. But maybe you are fine with that.

The big problem here is that most bad products developed, most wars, fights ... are the result of incorrect assumptions. People ass-u-me that they know things they don't know. Or that they know what someone else knows or is capable of.

Maturity is the human ability to know that we don't know everything, and just have to be openminded.
