My participants don't match the prescreening I selected

If you have participants in your data who don't match the demographics you ask for, please first confirm that the prescreening data provided by participants does not match the screeners you applied. You can do that by downloading the demographic data for your study.

Please note that the demographic data is accurate to the time of export, rather than to when the study was taken. Consequently, if there has been a delay in downloading this data some participants may have updated their prescreening responses, and their new responses will be reflected in the download.

If the participants' data from the export matches the screener but they have given you contradictory answers in your survey, please get in touch with them to ask which response is correct and if necessary, update their information within Prolific. If the answers they have given to Prolific or you are not truthful, this is valid grounds to reject the submission, and if necessary, report them to us via the 'report participants' menu option:


Please note that rejections can only be made on the basis of inconsistent screening responses if the questions within your survey are presented exactly as they appear on Prolific. This is to avoid rejecting participants because of subjective misinterpretations, arising out of any differences in wording between your screening questions.

If your survey software supports it, you are allowed to redirect participants who provide inconsistent screening responses to a separate end of survey message, which asks them to return their submissions. Please see here for further guidance on this.
