I'm constantly overhauling my own bias and opinions on subjects when presented with new information, I don't do this actively - its more subconscious, which is against the results of these experiments. The results were the subjects estimating a scenario (after being told they were deceived). The scale of measurement was the positive and negative bias they had towards themselves.

They started with a negative bias, which was then contradicted by a neutral fact. The outcome was a negative leaning estimation.

The others started with a positive bias, which was then contradicted by a neutral fact. The outcome was a positive leaning estimation.

A logically sound conclusion, a "mean" outcome. This doesn't seem like some kind of eye-opening revelation... am I missing something here?
