I am planning to use Prolific to recruit participants to rate some videos. For that, I will have some check questions to make sure that they watched the whole video - if they do not, the data will be useless.
Therefore, I considering rejecting (kicking out) ones who fail the check questions mid-survey (not a hard rejection, they can still return). Is this legit on Prolific? I think in this way, less work for both sides: I do not need to go through their answers, they don’t need to complete the whole survey and get rejected.
