On Prolific, you have the option to enter prescreening criteria to filter the participants you need.

Explore the full list of our participant demographics here!

Here are a few examples of the demographic criteria you can currently filter by:

  • Sex
  • Age
  • Nationality
  • Country of Birth
  • Current country of residence
  • Within the United States: Current US state of residence and US state of birth
  • First Language
  • Ethnicity
  • Employment status & domain
  • Student status & field of study
  • Parents' education level
  • Political affiliation
  • Religious affiliation
  • Sexual orientation
  • Handedness
  • Marital status
  • Socioeconomic statues
  • Participants' approval rate (how well did participants do in past studies?)

To play around with our prescreening feature and see how many participants qualify for each criterion, simply sign in, go to your Dashboard, click on "Create new study" and go to step 3 "Prescreening".

Please note: All prescreening criteria are self-reported. The only criterion that we actively check is "Current country of residence".

Also, participants can't immediately change their prescreening answers. They can delete them, but will only be able to re-enter them after the currently active studies are completed. 

Whenever researchers have suspicions about accounts they can report the relevant participant IDs to us. Many researchers have done this in the past and helped us catch some of the bad guys.
