Most leading universities have graduate programs where the masters and doctoral students need to survey a cross-section of the population to prove (or disprove) a theory. By signing up with these university sites you can make money or earn prizes.
These are usually very interesting surveys and I have participated in experiments regarding my views on race and politics among many other topics. Many of the surveys pay with Amazon e-certificates that you get very quickly after completing the survey (TIP: log into your amazon account and under “your account” add the gift card code to “apply a gift certificate/card to your account”. That way there is no losing the email). Others give you a percentage (say 1/10) chance of winning a prize. I have won many gift cards through these lotteries – they usually give pretty good odds!
I check these sites often as they usually don’t email about experiments. I say experiments but really it’s just reading some material and answering questions – you answer from the comfort of your home and they interpret the results! Here are the ones I am a part of:
UCLA Anderson School of Management Behavioral Lab
Psychological Studies at Harvard University
Lewis & Clark College Behavioral Health & Social Psychology Lab – take survey to sign up
