Adam Smith's Personality Theory
Criminals often share a similar set of personality traits leading to people to suggest that personality is a theory of why people commit crimes (Marsh, 2006). Some of the personality traits found in criminals include: lack of empathy and remorse, high impulsivity and tendency for aggression to name a couple. These can arise from multiple situations for example, lack of socialisation, traumatic events and lack of rewards for acceptable behaviour (Siegal, 2008). Smith did possess all three of the traits included above as he showed a lack of empathy for the crime when questioned by police, he was very impulsive especially with his anger and he most differently had a tendency for using aggression and violence, these arose from him having no friends and being bullied by his peers.
