mails.tsinghua.edu.cn - Prolific Researcher Reviews

I completed the survey, and I did not receive a code. I immediately sent a message to the researcher with a link to the ending page, and I told the researcher that I took a screenshot of the completion page that says "We thank you for your time spent taking this survey. Your response has been recorded." I took a bit longer than the average completion time and the intended completion time. Today I received a message that I was screened out and paid .14. I was not screened out. I completed the entire study and received the message that my response was recorded. This is very unfair and unethical.

very simple and easy study. approved in few hours.
