Welcome! You are about to take a test on Lab in the Wild.



The test typically takes 12-15 minutes to complete.

 

Please read the following information carefully before proceeding.

Why we are doing this research: We are trying to understand how people make decisions so that we can design Artificial Intelligence (AI) that can help them in decision-making.

What you will have to do: You will be presented with a set of descriptions of different people. Your task is to find the optimal exercise for a person, given their description. The exercise should be doable by the person, maximize their capabilities, fit their fitness goal, their preference, and their resource. You will also fill out a questionnaire at the beginning and end of the experiment.

Potential risks: There are no risks anticipated in taking part in this study and you are free to leave at any time without penalty or loss of benefits to which you are otherwise entitled.

Privacy: Your responses will be kept anonymous. We do not collect any information that could be used to directly establish your identity.

Duration: Approximately 15 minutes.
