How do participants hear about Prolific?
Participants are primarily recruited to Prolific via word of mouth, including word of mouth via social media.
When Prolific was founded in 2014, our participants were recruited via three channels:
- Social media (e.g. Facebook, Twitter, Reddit, and various other online forums).
- Flyer distribution on university campuses.
- The Prolific referral scheme (ceased March 2019). This allowed participants to invite their social network to join Prolific, in return for small cash incentives for the referrer.
