The project is a follow up project to the FWF stand-alone project The Skeptical Perspective. In this project, the monograph Guido Melchior: Knowing and Checking: An Epistemological Investigation, Routledge 2019, KC, was published. KC accomplishes three major tasks:

1. It breaks new ground by developing the first thorough epistemic theory of checking.
2. It provides a novel explanation of enduring epistemological problems, such as the skeptical problem, via a theory of checking instead of, as is the usual strategy, by a theory of knowledge.
3. It settles a lively debate in epistemology by arguing that sensitivity is necessary for checking but not for knowing, thereby finding a new home for the much discussed modal sensitivity principle.

In this project, this approach will be further developed along various dimensions. To be more explicit, we will further establish this approach as a self-contained theory, extend it to cover other epistemic phenomena such as discriminating and testing, and develop the methodological approach of KC into a full-fleshed meta-epistemological account. Moreover, further epistemic phenomena beyond knowledge shall be explored, including implicit bias and methods to mitigate it. The main research goals of this project are:

1. To compare the central views of KC with rival accounts and to defend them against existing and future objections;
2. To find further applications of the sensitivity principle, including theories of discriminating and testing;
3. To develop in more detail the methodological account of knowledge-last epistemology applied in KC and to find further applications of this account;
4. To investigate epistemic phenomena other than knowledge including implicit bias and methods of mitigating it.
