Well, I think you are wrong ...

... Hey, wait a second ...

Maybe I am just a contrarian!?

A person who disagrees with a decision appears intelligent without ever having their ideas put to test.

There are many ways that things can go wrong. I was the first to disagree; then I must be intelligent.

BTW I have found myself making counter arguments just to appear intelligent. That desire to appear intelligent is a strong motivational force. I suspect that people in authority often make counter arguments to subordinates just to assert authority. I can see numerous motivations for people who just automatically disagree before assessing an argument.
