A common question we get is whether or not Prolific can help with dyadic studies.

We don't offer the experimental software itself, but we can provide the participants. At any given moment (during the day in your local time), there are hundreds of participants active on our site. This means that it should be possible to pair them up for dyadic experiments or run multiplayer games.

Prolific predominantly uses convenience sampling, meaning most of our study places are filled on a first come, first served basis.

However, we have several mechanisms to reduce this bias, and fairly distribute study places among active participants. These mechanisms can cause slight delays in the speed at which participants will sign up for the study. We call this system 'naivety distribution'.

We have separate guidance on running studies on couples here: How do I run studies with couples?
