Group decision-making

Cognitive biases in group decision-making (HREC 1749615.1)

Introduction

The aim of this study is to assess how groups make investment decisions collectively, and in particular whether there are biases. This project has been approved by The University of Melbourne’s Human Research Ethics Committee, and internally funded by The University of Melbourne.

What I will be asked to do?

Should you agree to participate, you will complete a computer task both individually and in a randomly allocated group of three. The task involves trading in an experimental stock market. You will be given instructions and information on how the stock market works, and will be required to use your judgement to place trades with the objective of maximising your experimental cash holdings.

 

The estimated time of commitment will be about 120 minutes. Participation in this study is completely voluntary and the information collected will remain confidential. You will receive between $30 and $50 for your participation. Part of the payment will depend on your performance in the trading games.

How will my confidentiality be protected?

Any identifiable data which you provide will be stored in password-protected files, and will only be accessed by the researchers. The information you provide will be safeguarded subject to any legal requirements, and will be destroyed at least 5 years after final publication of results. Any publications or presentations resulting from this study will be based on de-identified data only.

What if I want to withdraw from the research?

Participation in this research is completely voluntary. You are free to withdraw at any time and to withdraw any unprocessed data previously supplied. This would have no effect on your relationship with any member of the Department of Finance at the University of Melbourne. It would not affect your grades, assessment or any treatment that you would otherwise be eligible for.
