In survey research, the tendency of a respondent to answer in a predictable way independent of the question content refers to:

Answering in a predictable way regardless of question content is response bias, a fixed answering style.

Experimenter bias arises from the researcher's own expectations shaping the results, not the respondent's set.

Measurement bias is a broad systematic error in the instrument or process, not this response habit.

Psychosocial effect concerns social influences on behaviour, not a patterned answering tendency.

Common forms include acquiescence, always agreeing, and extreme or midpoint responding.

Reverse worded items help detect and reduce such response sets.
