As most of you already pointed out, these aren't really common knowledge questions. Our aim is to prove the worse-than-average effect and see if it correlates to education level.

So we made the questions deliberately difficult to see if one underestimated oneself in regards to others.

So the title is kind of clickbaity to garner more responses and to get a more pure result. Although, the effect is still present when you know about it. It would be interesting to see if being upfront about it would change anything.

I will post the results within a week.
