The need to be right

I thought Universities was a place were knowledge, even common knowledge was supposed to be questioned. Only a minority of lecturers operate like this, you find them if you listen closely because from time to time they say things like...

- Do not blindly believe in what anyone says and do not believe what I say, go and look it up yourself and only after meticulous research place it on a scale of certainty in your head. Because in the future only 50% of what you learn here will be shown to be true. Be comfortable with doubtful facts and realise that most facts sits on a scale of certainty from 1-100 and most things do not sit at a hundred.

And then we have the majority of lecturers AND students. They don't care what the fact is, it can be anything they've read out of a ding ding newspaper as long as they said it, it's true and they will defend it to their death.
Their need to be right, to look good, to have respect is so much greater then their thirst for truth.

Can you now imagine how bad this yucky characteristic is in a politician?!
It makes me sick to the core.
