Surveys often promise that your answers are "anonymous" or "confidential". Those words are not quite the same, and the difference matters. Here is an honest look at what happens to your identity when you answer a survey or join a study.
Truly anonymous data cannot be linked back to a person by anyone, including the people who collected it. A paper survey with no name, dropped in a box, is close to anonymous.
Confidential means the people running the research know who you are, but they promise not to reveal your identity to others, including the client. Most panel research is confidential.
Pseudonymized data replaces your name and contact details with a code, such as a long random number. The key that links the code to you is kept separately and securely. Data protection laws such as the GDPR treat pseudonymized data as personal data, because it can still be linked back with the key, so it remains protected.
A panel needs to know who you are to do its job:
So the panel holds your identity, and the honest promise is confidentiality: your identity stays with the panel and is not handed to the brand or agency that commissioned the study.
When a study ends, the research team usually delivers:
The client sees that "45 to 54 year olds in the Midwest preferred option A", not that you did. In some projects the agency receives a dataset of individual responses, but each row is identified only by a code.
Small groups need extra care. If a result describes a very small group, such as three people in one town, a careful research team combines or hides it so nobody can be identified from the details.
Your written answers may be read word for word and quoted. That is why it is wise not to include your name, contact details, employer or other identifying information in them. Many research teams also remove personal details they find before sharing quotes. See our guide to open-ended answers for more tips.
Focus groups, interviews and product tests filmed on video are, by nature, less anonymous. People can see your face and hear your voice. That is why:

Some surveys ask about health, money, religion or other personal subjects. These questions should always be optional, should come with a clear explanation of why they are asked and should be handled with extra security. You can skip anything you are not comfortable answering.
Not from a properly run study. Results are reported in groups, and your identity is not shared with clients. If a survey is run by your own employer, read its privacy notice carefully, because the rules can be different.
Panels mainly handle invitations, quality checks and rewards. Quality checks can involve looking at responses, for example to spot copied text, but your answers are not used for anything outside the research.
