I'll give you my favorite one: People CREATE precisely what they try hardest to avoid.

Germaphobes and obsessive types often routinely put paper on public toilet seats and let it fall on the floor when they're finished because they don't dare touch it. They don't flush because they refuse to touch the flush handle. So when you walk into a public restroom with toilet paper all over the floor and a toilet full of wretched feces you blame low-class slobs or vandals but it's actually more likely neat freaks who made that mess!

People who are afraid of being treated unfairly will unintentionally treat others unfairly in an attempt to ensure that no one is taking advantage of them.

It's a fascinating phenomenon which I have seen in hundreds of people for decades.
