Seems that we have learned that P(A&B)<=P(A).
But I wonder whether we have an anchoring problem here. I myself used round numbers and notice that the median is a round number and that the probabilities go down in steps of 0.05 (and the mean follows suit almost linearly).
If anything the compound probabilities should show more or less geometric progression.
Anchoring to one of the values and then just roughly correcting for the difference in phrasing will not work (i.e. don't add any precision).
Do I notice this correctly? Can this be fixed? How?
I rated the second question as more likely than the first because I think "most traits" means something different in the two questions.
This is an experiment to use polls to tap into the crowd knowledge probably present on LW.

This being an experiment I do not announce it to be regular. If it is successful I may. Or you may. In that case I recommend the following to make this potentially more usable:
