HCD.10:6 - Bias-Annotation

Lenses: Gov, Arch, Onto/Epist, Prag, Did. Scope: selecting variation, timing, task mixing, retrieval, source, support, and challenge changes across bounded human practice episodes.

Recurring bias	Likely drift	Repair
desirable-difficulty bundle	Delay, retrieval, interleaving, source removal, and harder tasks are applied together.	Select each feature by a named target and preserve separate failure interpretations.
calendar-effect bias	Scheduled dates are treated as spacing effect, transfer, or retention.	Name repeated episodes, intervening practice, conditions, and the separate inference Method.
spacing-retrieval conflation	A later episode is assumed to require unaided recall.	Specify retrieval, sources, tools, AI, and human help independently of timing.
interleave-everything bias	Random mixing replaces task-similarity and Method-selection grounds.	Interleave only when discrimination among alternatives is part of the target.
harder-is-better bias	Difficulty is increased despite unstable basic performance or invalid access.	Stabilize, diagnose the limiting condition, and progress one warranted feature.
support-removal bias	Tools or references belonging to later Work are withdrawn as proof of progress.	Change support only for a stated human contribution or evidence use.
failure-as-loss bias	An unsuccessful changed-condition attempt is called lost capability.	Differentiate applicability, access, expression, adaptation, enactment, and support.
scheduled-proof bias	A later task is reported as transfer or retention by date alone.	Preserve task, support, delay, intervening use, and route interpretation to HCD.12/HCD.13.
