Hailed as 'father of criminology', shifted emphasis in crime research away from a moralistic discourse towards a more scientific and credible realm (evolutionary influences and genetics)
Lombroso also failed to consider that many of the criminals he studied had suffered from a history of psychological disorders which may have confounded the findings
Lombroso failed to recognise other causes of crime within his sample (most suffered psychological disorders- therefore biological reductionist as takes a narrow view towards criminal behaviour)
This is a weakness as it is stating that if someone has the genes to be a serial murderer they will be and also ignores environmental factors like poor diet that could lead to different physical characteristics
