How do you avoid confirmation bias when interpreting usability test actions?

This tests whether you recognize that prior beliefs distort observation and know concrete mitigation tactics for live usability studies. A strong answer defines confirmation bias as the tendency to seek confirming evidence while dismissing disconfirming data, then outlines guardrails such as silent observation, writing notes before debriefing, inviting neutral observers, and framing predictions as falsifiable hypotheses before the session. A red flag is claiming you simply stay objective or trust your gut without naming specific techniques.
