Eligibility: all twins aged 18-85. 

The purpose of this study is to examine personality, group membership and processes, political attitudes, and health.

Specifically, this will be the first study in Australia to take both genes and environment into account to find out:

  • Why some people are happiest while in their own company, and shun social gatherings, while others are
    members of multiple different groups
  • Why joining groups can be conducive to mental and physical health
  • How political and racial attitudes are co-shaped by genetics and socialization

What is involved?

If you choose to be involved in this study you will be asked to complete an online survey that includes questions about a range of factors, including personality, group memberships, attitudes towards particular groups, and your opinions about various political and social issues. In addition you will be asked questions related to your physical and mental health. Participation in this study should take approximately 40 minutes.

When you have completed the survey you can also enter a draw to win one of four iPads (the iPads have already been awarded) or one of twenty $50 Coles/Myer gift cards (still available)!
