People quickly decide another person’s character from just looking at their face and these impressions influence crucial decisions in everyday life. The researchers are studying first impressions from faces because these impressions have important social consequences, influencing hiring decisions, dating choices and even court case outcomes. This study will lead to unique insights into the genetic basis of individual differences in these first impressions, including answering an age-old question: why do we trust others?

What is involved?

You will be provided a link to an online survey where you will be asked:
