You need to proof read. Try reading your essay out load. That was Larken's advice to me and it worked much better than re-reading silently (did you even do that?).

What you call "basic psychology" I attribute to cognitive crippling in early childhood. Few escape, but it's not natural. It must be inflicted on people to make them easily controlled. The few of us who have overcome our early pressure to conform and obey have done so because we used our minds, we questioned, despite the negative feedback (psychological and physical punishment for challenging official dogma).
