The Confabulation Risk in AI Interview Summaries: Why Fluent Machine-Written Findings Invent Coherence That Was Never in Your Data

Your AI summary reads like a sharp senior researcher wrote it. That fluency is the danger. Confabulation is the models default mode -- assembling scattered fragments into a confident narrative no participant actually gave. The defense is not better prompts. It is claim-level traceability.

The Screener Precision Trap: Why Tighter Recruitment Criteria Produce Homogeneous Samples and False Saturation

Tightening your screener feels like quality control. Past a certain point it is bias engineering. Over-precise criteria homogenize your sample, accelerate false saturation, and screen out the frustrated users whose pain would teach you the most.

The Transcription Fidelity Gap: Why AI Transcripts Silently Delete the Disfluencies That Carry Meaning

Your AI transcription tool produces clean, readable text. That is exactly the problem.

The Rehearsal Effect in Pilot Interviews: Why Testing Your Guide Contaminates Your First Real Sessions

The Context Switching Cost in Same-Day Interviews: Why Back-to-Back Sessions Produce Progressively Blended Data

By your fourth interview of the day, you are no longer hearing fresh participant stories. You are hearing echoes of earlier sessions layered over new voices. The context switching cost is not just about fatigue -- it is about how unprocessed data from previous sessions contaminates your perception of the current one, creating blended insights that belong to no single participant.

The Authority Gradient in Research Settings: Why Participants Match Their Response Sophistication to Perceived Researcher Status

When a PhD researcher introduces themselves with their full title, participants unconsciously elevate their vocabulary, construct more elaborate justifications, and suppress simple truths that sound unsophisticated. The authority gradient does not just intimidate participants into agreement -- it reshapes the cognitive register in which they respond, producing data that reflects performed intellect rather than lived experience.
