The study of eugenics claimed that inheritance could explain the presence of simple and complex human behavioural characteristics
The idea that we can identify a criminal gene is now discredited in the early 20th century
Eugenicists were obsessed with the fear that the human race was in danger of 'degenerating' because the poor were breeding at a higher rate than the working class
Eugenicists believed that the poorer population were passing on an inferior criminal gene for low intelligence, insanity, poverty, and criminality
Eugenicists argued that the 'genetically unfit' should therefore be prevented from breeding by the compulsory sterilisation of criminals to prevent them from giving birth to criminal offspring
Osborne and Wet (1970s) provides support for the eugenics theory as they found that 40% of boys whose fathers had criminal records had criminal records themselves as opposed to 21% whos fathers did not have criminal records
Forced sterilisation is seen as a breach of Human Rights
Nazi 'racial purity' policies became part of the justification for the Nazis' genocide of supposedly 'inferior' races
All Nazi and EUgenic policies are widely condemned in the modern world
