Study Information
Thank you for your interest in our study!
This is the first session of a two-part experiment. After completing this session,
you will be invited to participate in the second session, which will take place approximately one day later.
Please read the following information carefully.
Participation in this research is voluntary, and it is entirely your choice whether or not to take part.
If you have any questions or need further information about the study, feel free to contact us at:
aswath.chandrasekaran@student.uni-tuebingen.de
1. Purpose
This study aims to investigate human decision-making and exploration processes.
2. Procedure
You will begin by receiving detailed instructions about the task, followed by a short comprehension check to ensure that you have understood the procedure correctly.
After this, you will proceed to the main task. Please note that your performance in the main task will influence your bonus payment, which will only be issued after you have completed both sessions of the study.
The total estimated time for this session is approximately 10 minutes.
3. Compensation
You will receive £1.50 for your participation. You can also earn a bonus of up to £1.50 depending on your
performance in the task, payable after you complete Session 2.
4. Data protection
Once we have awarded you your bonus payment, your Prolific ID will be deleted from the study data. The experiment
data will be stored under a randomly assigned participant number on a server at the University of Tübingen. This
means that it will become impossible to link the study data to you. All data collected during this study will be
treated confidentially and all individuals with access to your personal data are obliged to maintain data secrecy.
We are not responsible for the handling of your personal data through the Prolific platform.
The study data may also be made publicly accessible via research databases or scientific publications (typically via
the internet). This makes it possible for other researchers to check or replicate the results and enhances the
quality of scientific research. The study data may also be used for new research questions going beyond the purposes
of this particular study. The data is stored anonymously, treated confidentially, and used only for scientific
purposes. You are free to withdraw, in which case recorded data will not be used (cf. point 6).
5. Voluntary participation
Your participation in this research is entirely voluntary. There will be no repercussions when canceling your
participation.
6. Right to refuse or withdraw
You do not have to take part in this study if you do not wish to do so. You are free to withdraw your consent and do
not need to provide a reason for your withdrawal. Participants who drop out of the study for any reason (e.g.,
technical issues) are eligible for full or partial compensation. Please contact
aswath.chandrasekaran@student.uni-tuebingen.de and include a screenshot of the experiment website if possible. If you withdraw from the study before data collection is completed, your data will not be used. If you withdraw from the
study after completing the study, but before bonus payments have been processed, you can request the deletion of
your data. After the processing of bonus payments, your Prolific ID will be removed from the study data and it will
be fully anonymized, making it not possible to link you with your data.
7. Risks
Your participation does not involve any physical or emotional risk to you. You are free to withdraw at any time.
8. Insurance coverage
Not necessary for participating in this study.
9. Responsible contact
If you have questions or if there are any problems, please contact aswath.chandrasekaran@student.uni-tuebingen.de.
You can also use this email to request the withdrawal of your data.

Welcome to the Diagnostic Dilemma!
You’ve just received results from a medical test — but what should you actually make of them?
Numbers are staring back at you, but without a medical degree, they’re not always easy to interpret. Do they mean something serious? Something minor? Or nothing at all? It's the kind of uncertainty that can easily trigger a scroll through worst-case scenarios. 😱
But don’t worry — you’re not here to panic. You’re here to think clearly.
In this study, you'll go through two short sessions:
Session 1: You'll be shown test results — just the raw numbers and facts. Session 2: You'll see the same test results, but this time with additional background information to help you interpret them.
Click on Continue!
In each session, your task will be two-fold:
1. Estimate the probability that the individual tested actually has the condition (based on the test results).
2. Make a medical decision — such as whether to seek treatment, wait, or consider second opinion.
You’ll be stepping into the role of a thoughtful decision-maker — someone weighing evidence, not reacting to fear.
Great! You’re all set to begin.
You’ll now go through a brief tutorial to get familiar with how the tasks work.
