Research Participants Institute
Research Participants Institute has some very interesting surveys. I have done one survey for them – reviewing a court case. It’s very interesting and quite easy to do and I really enjoyed the survey.
I also received second survey invitation, but I didn’t get the chance to do the survey because the quota was filled when I tried to take the survey!
The reward was very good – they paid me $17 for the survey and they paid (via check) very quickly!
