Comparing risk-taking and digit ratio (2D:4D) in offenders and non-offenders

Taja Anderson


Offenders differ from non-offenders in their propensity to engage in risk-taking behaviour. The ratio of the index and ring fingers (2D:4D), a proxy of prenatal testosterone exposure, has been linked to risk-taking behaviour. The present study compared risk-taking in 45 male offenders and 66 non-offenders using the Balloon Analogue Risk Task (BART). Furthermore, it sought to determine the relationship between their 2D:4D ratios and risk-taking behaviours. No significant differences were found between the two groups in their risk-taking behaviour and no significant correlations were found between 2D:4D and risk-taking in either group. These findings are discussed in relation to previous research, limitations of the current study and possible future research.
