A study of online interactions developed by Stanford University in partnership with Airbnb.

Consent to Participate in a Research Study

You are invited to participate in a research study about the effect of participation in online communities on your social life. We are particularly interested in learning how your interactions with people evolve over time. The game has been developed by a team of researchers at Stanford University in collaboration with Airbnb.

If you agree to be part of the research study, you will be asked to answer some preliminary questions and participate in a game. The preliminary questions are related to your experience with online communities. We will also ask for your name and email address (confidential data).

The game you will be playing in this study is an “investment” game, where you will play against other participants and decide how many points to give to them or keep for yourself. We will use all the points you accumulated in the investment game to determine your total score.

We cannot and do not guarantee or promise that you will receive any benefits from this study. There are no risks or benefits to you associated with this research.

The data we will be collecting from you will be shared with Airbnb. Airbnb will create an anonymized version of the data (no confidential data) and give it back to Stanford University to retain for future research.

Participation in this study is completely voluntary. You must be at least 18 years old to participate in this study. Even if you decide to participate now, you may still stop playing at any time. You may choose not to answer any of the questions or to stop playing the game for any reason. You may choose to ignore our reminders and not come back to play the game.
