So when I think I have no idea on a true/false question I'm probably right, but when I think I have a bit of an idea I don't (admittedly with an insignificant data sample).

This is a stupid test and doesn't test whether you have the right amount of confidence in your knowledge in a sensible way. Take this example:
"Wilt Chamberlain was shorter than 7 feet"
I mean, I have no idea really, but most people are well under 7 feet tall aren't they? So really I'm answering on the basis of what I think the psychology of the questioner is, rather than anything else.
This is likely to have very little correlation with how people behave in their lives when it comes to over or understating their confidence in their assertions.

What I can basically take away from this is that I'm the general knowledge equivalent of
Leeroy Jenkins.
Edit: Also feel this would be a more accurate test if it was timed.

This is retarded. So you think False but you don't know... so put False and 50%.
So? Just do it.

Seems I'm a bit overconfident, and especially when I think I'm sure.

Did it the other day but forgot to copy and paste results. If I remember correctly I got 30 right, answered 12 at 100% and got one of those wrong. Everything else I gave 50% confidence to.
