What the literature leaves open
The gap in the literature is the lack of a clear explanation of how pure epistemic norms can capture substantial normativity. The paper identifies the need for a new approach to understanding epistemic norms.
The paper argues that an additional epistemic condition on trusting is needed to explain these instances.
I provide an account of Nietzsche's virtue/vice conception of skepticism that is currently lacking in the literature, and that is worthy of the attention of virtue epistemologists.
While much has been written on the harms and benefits of free expression and the associated rights thereof, the epistemic preconditions of justified censorship are relatively underexplored.
A major open question in the borderlands between epistemology and philosophy of science concerns whether Bayesian updating and abductive inference are compatible.
The lack of a clear understanding of the cognitive mechanisms behind participants' responses in Gödel-style setups.
One reason for this is that it remains an open and empirical question the extent to which a normal epistemic subject ought to trust their faculty of memory to provide them with a reliable memory belief forming process and with this reliably accurate memory beliefs. Addressing this problem is beyond the scope of this paper, but it is a serious enough pitfall to highlight.
The lack of a formal architecture for verifying genuine independence and convergence of evidence in epistemology. The need for a structure to verify independence and convergence beyond Bayesian high posterior probability or other methods.
Collaboration with xAI to address the limitations of Grok (xAI). Updates and improvements to Grok (xAI) to make it suitable for CM-2 compliant workflows.
The CM-2 Cognitive Memoisation protocol has specific requirements for epistemic governance. Grok (xAI) has several material limitations that prevent reliable use as a compliant platform.
It highlights the need to develop more nuanced and context-sensitive approaches to knowledge production.
The paper argues that scientists' self-defensive motivations can hinder critical engagement with science. The paper suggests that the lack of transparency and accountability in scientific communication can contribute to uncritical trust in science.
The paper argues that previous approaches have insufficiently accounted for the various ways in which members of marginalized groups have epistemic advantages in scientific contexts.
Insider-Outsider Members of Scientific Communities and Their Epistemic Advantages in Critical Reflection · 2026 · DOIThe gap between the traditional focus of epistemology on individual minds and the reality of collective epistemic achievement. The lack of recognition of cognitive limitations in traditional epistemology.
The rejection of introspection principles in recent epistemology has theoretical costs. There is a need to provide a way to solve the dilemma of rejecting introspection principles.
Future research could explore the implications of the paper's findings for social justice and addressing oppression. It could also examine the role of affectivity in other contexts, such as education or healthcare. Further research could investigate the relationship between affectivity and epistemology in more depth.
Standpoint Epistemology and the Value of Emotions: Is There an Affective Advantage to Being Oppressed? · 2026 · DOIThe gap is related to the neglect of the role of affectivity in the context of oppression. The paper aims to address this gap by exploring the epistemic value of emotions.
Standpoint Epistemology and the Value of Emotions: Is There an Affective Advantage to Being Oppressed? · 2026 · DOIFuture research could explore the implications of the asymmetry charge for the Reasons as Evidence view. It could also investigate alternative accounts of normative reasons.
The interpretation of the epistemic side-effect effect remains contested. Prior work has not fully explained what participants take themselves to be attributing when they say that an agent knew or did not know.
Knowing, Risking, and Being Responsible: A Qualitative Study of the Epistemic Side-Effect Effect · 2026 · DOIIt notes that previous findings are mixed and do not provide a clear understanding of the mechanisms underlying belief updating.
The use of intuitive judgments is prevalent in philosophical practice, but its validity is often questioned.
The paper argues that the opposite extreme - uncritical trust in science - is largely overlooked. The paper suggests that this neglect is potentially driven by scientists' self-defensive motivations.
The discussion is limited to three recent attempts to meet the challenge of showing how pure epistemic norms can capture the substantial normativity they…
Further exploration of the concept of vulnerability in trust, - Investigation of the relationship between trust and various epistemic states…
The paper identifies a gap in traditional epistemology's neglect of the moral foundations of inquiry. It highlights the limitations of Gettier-style analyses that detach justification from ethical and contextual concerns.
