Epistemic dysmorphia: a working definition

Epistemic dysmorphia is a term introduced by Anthony R Brand (2026) for a sustained, self-reinforcing distortion of students' perception of their own cognitive development, produced by fluent output, sycophantic feedback and assessment that rewards products without verifying process.

What it names. A student who hands the formative work of an essay — the reading, the weighing of sources, the building of an argument — to a large language model (LLM) still submits an essay, and often a better one. Every signal that follows reports progress: the prose is fluent, the tool is encouraging, the grade is good. Epistemic dysmorphia is the gap that opens between the student’s picture of their own development and the development that actually took place. Because each signal confirms the picture, the gap does not close of its own accord; it deepens.

Scope and degree. It is most pronounced in students’ written assignments where generative AI — most commonly an LLM — is used in some aspect of the writing process. Its degree reflects, in part, which aspects of that process have been offloaded to the LLM, and how far each has been offloaded.

How it differs. It differs from neighbouring concepts such as the Dunning–Kruger effect, which arises from a lack of skill and is exposed when performance is tested. In epistemic dysmorphia, the three conditions — fluent output, sycophantic feedback, and assessment that rewards products without verifying process — compound one another: the assessment tests the product, not the capacity, so the result silently accepts and reinforces the distortion, rather than confronting and correcting it.

Why “dysmorphia”. The word comes from clinical psychology, where dysmorphia names a persistent mismatch between self-perception and reality that holds out against contrary evidence. That structure is what carries over, not the pathology. Epistemic dysmorphia is not a diagnosis, and it is produced by conditions — the tool and the assessment around it — rather than by a failing in the student.

Its counterpart. On the teaching side, pedagogical dysmorphia names an educator’s mistaken belief that an assignment still assesses what it was designed to assess. The two confirm each other.
