According to metacognitive myopia (MM), decision makers are highly sensitive to complex samples, but inadequate monitoring and control prevent them from critically evaluating sampled stimuli. In a novel paradigm combining advice taking and implicitly directed forgetting, we investigated the role of memory in assessing the validity of advice. Participants (Ntotal = 159), who were asked to estimate the cost of building a house on the basis of (in)valid price quotations from two construction firms, attempted to process and later correct invalid information rather than ignore it in their final judgements. Strikingly, MM biases in memory and judgement showed no coherence. In other words, participants displayed a preference for recalling and correcting invalid advice rather than forgetting it. The maladaptive consequences of this process are discussed.
