We know what stops you from thinking forever: A metacognitive perspective

This commentary addresses omissions in De Neys’ model of fast-and-slow thinking from a metacognitive perspective. We review well-established meta-reasoning monitoring (e.g., confidence) and control processes (e.g., rethinking) that explain mental effort-regulation. Moreover, we point to individual, developmental and task design considerations that affect this regulation. These core issues are completely ignored or mentioned in passing in the target article.
