(Full LW post and raw data here.)

From the results of the calibration questions:

It looks to me like everyone was horrendously underconfident on all the easy questions, and horrendously overconfident on all the hard questions. To give an example of how horrendous, people who were 50% sure of their answers to question 10 got it right only 13% of the time; people who were 100% sure only got it right 44% of the time. Obviously those numbers should be 50% and 100% respectively.

This builds upon results from previous surveys in which your calibration was also horrible. This is not a human universal - people who put even a small amount of training into calibration can become very well calibrated very quickly. This is a sign that most Less Wrongers continue to neglect the very basics of rationality and are incapable of judging how much evidence they have on a given issue. Veterans of the site do no better than newbies on this measure.
