Darwin's Doubt (DD) – a thesis according to which the probability of the human cognitive mechanism's reliability given non-guided evolution is low – is central to Plantinga's Evolutionary Argument Against Naturalism and his suggestion that the adoption of guided evolution thesis is preferable from a theory choice point of view. In this article I'll argue that there are three fundamental failures in Plantinga's argument. First, I argue that Plantinga's argument for DD is question-begging. Second, I point out that this very same argument is not in accordance with the way the evolutionary scientists usually reason. And finally I argue that the replacement of non-guided by guided evolution violates some reasonable belief-revision procedures in the history of science.
