I think problem is deeper. If one predicts heads as result of coin toss and other predicts tails, than one of them will be right. It says nothing about their abilities to predict. We always can find some outlier who predicts results different from majority of pollsters. The keyword is 'always': if such a possibility always exists (probability of existence P=1), then we can't extract any information from it (-log_2 P == 0).

To extract information we need to carefully revise methodology behind outlier predictions, and such an activity is a complex task for skilled data analyst.
