Qualitative evidence is easier to follow when a team can tell one respondent from another.
That continuity does not require exposing a participant’s real identity.
Participant aliases provide a consistent way to refer to respondents in the research experience while reducing unnecessary identity exposure.
A customer may need to understand that several answers came from the same person, compare that person’s responses across a study or discuss a specific respondent internally. An alias supports that research context without making the person’s real name the identifier.
The design separates the evidence needed to interpret the study from personal identity that is not necessary for that job. That supports candid participation while keeping the research usable for customers.
Participant trust and customer evidence are connected. A clearer identity boundary helps protect the conditions in which professionals can give useful feedback without turning the research result into an unnecessary directory of real people.

Participants are told during signup that their names are anonymized by default in research studies.
