Be sure to read the study description carefully before signing up for a session. You must meet any additional eligibility criteria described there.

Verify the location of the study, and that you can show up on time. Participants must arrive on time to be eligible for any payment. Many experiments require a minimum or specific number of participants, so it is important to show up if you have signed up. The researcher may not be able to run the experiment if there are not enough participants present.

Studies usually last 1 to 2 hours (payments are higher for longer experiments).

Studies may include individual tasks or involve interactions with others.



For most lab studies conducted at HBS, payments range from $15 to $25, and can be as much as $35 after bonuses. Minimum payment of $10 if you sign up, are eligible, and show up.

Note: To receive any payment, you must arrive on time!
