Differential association theory, created by Cohen, suggests that criminality is participation in a cultural tradition and is learnt from the people around us.
The more people around them with pro-criminal attitudes and the more extreme those attitudes, the more likely the individual will go on to commit crime.
Reinforcement in differential association theory works beyond approval, criminals often receive material benefits from committing crimes and might see these rewards as better than potential rewards from not offending in their community.
Sutherland's work was a complete rejection of the idea of born criminals, in 1930s America genetic ideas about criminality were used to perform racially motivated for sterilization.
According to differential association theory, people are most likely to cause criminal offences if they're male and then late adolescence to early adulthood.
There is no easy way to separate the genetic and social influences, people who are genetically likely to become criminals might seek out other people with criminal attitudes to socialize with, a process known as niche picking.
