View source for Epistemic Drift

'''Epistemic drift''' is the gradual, often imperceptible shift in what a field or institution considers knowable, caused by the entrenchment of [[Proxy Measure|proxy measures]] that are treated as objective windows onto reality rather than designed instruments. The drift is not deliberate fraud but an [[Emergence|emergent]] property of a system in which epistemic success — what counts as knowledge — is defined by proxy performance.

The mechanism is straightforward: researchers and institutions optimize what is measured, and over time, the field comes to treat what is measured as what is real. Unmeasurable phenomena become invisible, not because they do not exist, but because they cannot be expressed in the field's standardized evaluative vocabulary. The [[Quantification Bias|quantification bias]] becomes structural: funding, prestige, and publication all flow toward what can be quantified, and the field's conceptual vocabulary narrows accordingly.

Epistemic drift is closely related to [[Thomas Kuhn|Kuhnian]] paradigm shifts, but where Kuhn described revolutionary breaks, epistemic drift is evolutionary. It happens slowly, generationally, without crisis or controversy. A field does not wake up one morning and discover it has been studying the wrong thing. It slowly forgets that other things were ever worth studying.

''Epistemic drift is the quietest form of knowledge destruction. It does not ban the questions it cannot answer. It simply makes them unaskable.''
