Eligibility: All twins – identical and non-identical - aged 18-65 years.

Financial decisions and behaviours can be very important influences on what outcomes we achieve in life, and impact on health and wellbeing. The purpose of this study is to investigate how genes and environment affect people’s financial preferences and decision making. By understanding how these behaviours pass between generations, governments and related services can design policies and measures to better support people’s desired life outcomes.

What is involved?

If you agree to participate the researchers will:

  1. Email you the study questionnaire. The questionnaire will take approximately 45-60 minutes to complete online and asks you questions about your willingness to take risks when making financial decisions.
  2. Once both you and your twin have completed the survey, the researchers will randomly select one of your answers each and pay you out in real dollars (an amount between $0-$37). Note, payments are based on your individual answers, which means you and your twin may receive different payment amounts. 
  3. The researchers may contact you one year later to complete a similar questionnaire.

For more information please read the study’s FAQ here.
