Do you sometimes base your opinion based off what other people say?

Yes. I often do. Especially if I think the person is an idiot.

What I like to do is listen to other people...usually ones who have different opinions. Usually I can figure out who is completely full of poo.

Depends.

If they have a point, then I'd think more on it and change my opinion a bit.

I don't usually though.

Only if those people have a good point..
(see what I did there)

No I always give the person a chance. Standards/opinions vary

[c=#800055]maybe if those people have a good point. [/c]

I have never done that or ever shall...

I try not to

nope

We all do that all the time.
