I hate cognitive biases. I read your comment right before I went to take the test. “Ha!” I thought to myself, “clearly members of Less Wrong wouldn’t be as effected. Why even bother mentioning it?” And then I clicked on the link while I thought about the singularity. “Hmm, 2100 is a decent year maybe it’ll be 20 years before that though...” And I filled in my race/education/sex. “Hmm maybe it would be after that though, due to...oh god, it’s the anchoring effect! Quick think of other numbers! 2090! 2110! Damnit. 1776! Wait that won’t work...”
And as I slowly worked my way down, by brain tried in vain to come up with alternate years. Until I finally reached the problem. “Is this really what I think, or am I just putting this answer because of that comment in the thread?” But it didn’t matter. The numbers were in the box, and I couldn’t convince myself to change them.
There it stood: 2100.
PS. Yvain, any chance you could look at the mean/median/mode/standard deviation of that problem before and after you changed the questions around? I’d be very interested in seeing how people were effected by anchoring.
