All studies on Prolific have a limit on the number of submissions researchers can reject by default. This is because a rejection negatively impacts a participant's Prolific Score, which could prevent them from taking part in further studies on our platform.
We typically find that the automatic rejection limit is sufficient, but if you reach the maximum number of rejections for your study and require more, you will need to get in touch with the Support Team to request an increase to this limit.
Before doing so, please review our article about when it is instead appropriate to ask participants to return their submissions.
Requesting a Rejection Limit Increase:
It is important to remember that we are a platform that serves both researchers and participants, so we will need to make sure that your rejection reasons are fair and in line with our guidelines. When you submit your request, we will ask for the following information:
- Name of study (including internal name)
- Study questions, the related concerning responses, and the relevant participant IDs (any format is fine)
- Any additional information that might be useful to assist our review (e.g. context about your study)
Please note, we won't be able to increase your rejection limit until we have this information. By providing this, you are helping us to make sure everything is fair for everyone on Prolific! Thanks!
