Cognitive Drag

Friction introduced by poorly structured context.

Cognitive Drag is the UX-facing name for the slowdown that bad context creates. Where Reasoning Tax talks about cost and Reasoning Load talks about work, Cognitive Drag talks about the feeling: the model responding sluggishly, producing meandering answers, asking unnecessary clarification questions, or generating verbose output that circles around the answer before landing on it. Users experience Cognitive Drag as the model "not getting it" — but the root cause is usually that the context made it hard for the model to get it.

Example
A user asks an AI writing assistant to "edit the blog post." The system context includes three drafts of the same post, unmarked, plus style guidelines from two different brand voices. The model's response is tentative and meandering — it hedges about which draft to edit and which style to follow, producing a 2,000-word response that could have been 400 words if the context were clear. The user experiences this as the model being slow and unfocused. The real problem is Cognitive Drag from ambiguous context.
