Questions

What are psychology games?

Psychology games turn real experiments about thinking and decision-making into something you can play. You make a choice, then learn what it says about how people think.

Are these psychology games free?

Yes. They run in your browser on PC and mobile, with no download and no sign-up.

Are the experiments based on real studies?

Yes. Mind Lab is built on published studies such as Asch (1951) and Tversky & Kahneman (1981). The source is shown after each experiment.

Can I compare my answers with other people?

Yes. After each experiment you guess how many players chose the same as you, then see the real share from everyone who has played.
