Primacy bias
Our brains tend to give more weight to people we meet first in a new, unfamiliar situation. In a UX study, primacy bias happens when UX researchers remember the first respondent more strongly than others.
Taking notes and recording your session with a participant’s permission can help you overcome this bias by interpreting the research findings more thoroughly and treating all participants’ answers equally.
Pro Tip: Conducting user research sessions can be exhausting. To prevent bias, split sessions over several days so you can rest and remain focused when interviewing people.
