Sorry if I'm just being stupid, but why does this go against the hypothesis of subjects "start[ing] from the anchor and continu[ing] in the direction of his/her unbiased estimate, but [not going] far enough." While the percentages are vastly different, the favored option is the same between biased and unbiased groups in both cases.
Also, and sorry if this seems like nitpicking, but in the example we talked about in the Mental Metadata I imagine the subject would have a much stronger feeling about their expected values than in these cases. That aside, interesting experiment.

If you just started from the anchor and moved toward your unbiased estimate, it would be impossible to end up on a different side of the anchor from your unbiased estimate. Thus, the amount of people on each side changing between anchored and non-anchored is evidence that something else is going on.

Yeah, I noticed that soon after posting but figured it would be kind of silly to edit out almost my entire post. And deleting it just seemed like a sort of suspicious behavior (considering that I was wrong).
