Where does Prolific source its participants from?

Participants are primarily recruited to Prolific via word-of-mouth or social media. Participants can also be invited to join Prolific by researchers via our “Bring your own participants” tool. In 2014, when Prolific was founded, participants were primarily recruited through social media, flyer distribution on campuses, and the Prolific referral scheme (ended March 2019).

How does Prolific advertise its services to participants?

We advertise Prolific as a way to earn money in exchange for contributing to world-changing research. Please view our “Become a participant” webpage for more information on how we set expectations with Prolific participants.
