Support for gender socialisation is provided by Heidensohn (1996) who suggested gender differences are the most significant feature of recorded crime. 95% of the UK prison population being male, men are cautioned more than women, for example men are 14 times more likely for burglaries and 8x more likely for robbery and drug offences. These results clearly demonstrate the presence of a cognitive bias in criminals, and we may be able to look to these biases to understand the cognitive factors that lead to criminality.
