Testable Minds is a platform where you can participate in many psychological/behavioral experiments and other studies from the world's leading universities. It is an ongoing thing, with a constant flow of new studies. You can participate in all studies available to you. Does this mean that I can participate in all studies? Yes and no. Different studies have different requirements and researchers are interested in a wide range of individual profiles, so there will be many studies for which you don't qualify. However, you won't see these studies anywhere. Only studies looking for your profile will be visible to you (you can increase their number by completing your profile) and yes, you can participate in all of these. You get paid for each study you complete, after the researcher approves your participation (so make sure you do the study properly!). Each study has a different participation fee, depending on duration, complexity, researcher, etc. Your participation fee will be added to your Testable Minds balance.
