Study Information

Thank you for your interest in our study. Please read the following information carefully. Your participation in this research is voluntary. It is your choice whether to participate or not. Please do not hesitate to write to us at alexandra[dot]witt[at]uni-tuebingen.de if you have any further questions regarding the study.

1. Purpose

In this study we investigate how humans integrate social information into decision-making processes.

2. Procedure

In the following, you will receive detailed information regarding the procedure of the study.

First, you will receive instructions on how the task works. Then we will ask you some questions to ensure you correctly understood the task. After that, you will get to try out the task, and finally do the task in full. Your performance in the full task will affect your bonus payment. The entire study will take about 45 minutes.

3. Compensation

You will receive £9.15 for your participation. You can also earn a bonus of up to £9.15 depending on your performance in the task.

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 alexandra[dot]witt[at]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 alexandra[dot]witt[at]uni-tuebingen.de. You can also use this email to request the withdrawal of your data.

Welcome, Explorer!

You’re embarking on an intergalactic adventure to uncover the secrets of mineral X, the most valuable substance in the universe! Mineral X powers starships, extends lifespans, and fuels cutting-edge discoveries.

Your mission will take you to two different planets. On each planet, you’ll explore sites to find out where mineral X is most commonly found. During each mission, you will be exploring two sites. One site has more mineral X, but that doesn't mean you will always find mineral X there. You will conduct one solo and one team mission per planet.

Depending on the planet, sites may look like this:

Planet A Example 1
Planet B Example 2

or this:

Example A
Example B

Your task is to identify the better site. Each site will be identified by an image, and the same images may appear on the left or right — their positions can change!

Solo Missions

In solo missions, you'll spend 8 days doing guided exploration: you’ll be told which site to visit, and you’ll see whether mineral X was found there. This is your chance to gather clues about which site is better.

Here’s an example of what you might see:

Example A
Example B

You found mineral X! 🙂

On Day 9, you’ll make a free choice. In total, you'll complete 50 solo missions per planet. Each one lasts 9 days: 8 guided, 1 free. Your bonus depends on whether you choose the better site on that final day.

Team Missions

In team missions, you'll first observe a different fellow explorer as they search for mineral X. Over 8 days, you’ll see reports from 8 different partners.

Their reports will look like this:

Example A

👎

Example B

After 8 days of observations, you’ll make one free choice — just like in solo missions, this is the choice that counts toward your bonus. Remember, one site is better, but it won’t always have mineral X.

Just like solo missions, there will be 50 team missions per planet, each lasting 9 days.

Summary

  • Your goal is to figure out which site is more likely to have mineral X.
  • Mineral X doesn’t appear every day, even at the better site.
  • You will be visiting 2 different planets, on each of which you will complete both solo and team missions.
  • Solo Missions: 8 days of guided exploration (you’re told where to go), followed by 1 free-choice day.
  • Team Missions: 8 days of observing different partners’ reviews, followed by 1 free-choice day.
  • Your bonus depends on how often you choose the better site during the final (free choice) day of each mission.
