I fully support using empirical evidence in the critical examination of ideas.

The question is not whether one dismisses empirical evidence (as someone suggested, but not me), but whether empirical evidence (the facts as I see them) are indeed the facts, or whether cognitive biases exist in the empirical data.

The critical rationalist says that empirical evidence is not the truth, that objective truth is a tentative model, a model that influences our observations, and that both ideas and observations should be subjected to critical tests (which consist of more ideas and observations).
