Researchers' Commitments and Privacy Policy

At ELSE, all information participants get during our studies is true. This implies:

  • We never deceive participants. For example, if we inform you that another participant is making a choice on which you then can react, this is indeed the case.
  • We keep our promises made to participants. For example, if we promise a certain payment, participants will indeed receive it.

In case we are responsible for a mistake that is to the disadvantage of participants, we will inform and compensate the respective participants.

We design, conduct and report our research in accordance with recognized scientific standards and ethical principles.

We stick to the terms of our privacy policy as stated below.

In case you find that during experiments we do not stick to our rules and regulations or in other ways ethical norms are violated, you can contact experiment@elseutrecht.nl or, if you wish, an independent mediator to complain about that, namely prof. dr. Ineke Maas (i.maas@uu.nl).


The data in the participants database will only be used to organize scientific studies at ELSE. The data will never be given to third parties. We use the data for the following purposes:

  • to inform participants about current studies at ELSE (lab experiments or internet experiments) and to invite them to such studies,
  • to make a scientifically motivated selection of participants for certain studies,
  • to administer show-up and no-show-up occasions of participants who registered for sessions.

There is no link between the personal data in the participants database and the data collected during a study.

Every participant can decide at any moment to unsubscribe from the participants database. Unsubscribing from the database implies that no further invitations to our studies are sent to that person.


During a study at ELSE data is generated based on the decisions made by the participants.

These data will only be used for scientific purposes by researchers at Utrecht University or by researchers elsewhere with whom we cooperate.

These data is never linked to a specific person. Thus, all answers that participants give are anonymous.

The generated anonymous data is used to write scientific articles and to give presentations. The end products are publicly available.

For questions please contact experiment@elseutrecht.nl.
