1876 Lombroso wrote L'Humo Delinquente in which he said criminals were genetic throwbacks - primitive sub-species biologically different from non-criminals
lacked evolutionary development, so their savage and untamed nature meant they found it impossible to adjust to civilised society and would inevitably turn to crime
atavistic characteristics
Lombroso argued that this sub-type had particular biologically determined characteristics linked to particular crimes, that made criminals physically different from the rest of us
atavistic characteristics
narrow, sloping brow
strong prominent jaw
high cheekbones
facial asymmetry
dark skin
extra toe, nipple or fingers
murderers: bloodshot eyes, curly hair and long ears
sexual deviants: glinting eyes, swollen, fleshy lips
fraudsters: thin and 'reedy' lips
also said born criminals were insensitive to pain, used criminal slang, had tattoos and were unenployed
Lombrosos research
examined facial and cranial features of italian convicts
examined skulls of 383 dead criminals and 3839 living ones
concluded 40% of criminal acts are committed by people with atavistic characteristics
S - contribution to criminology
credited for shifting criminology to a more scientific realm
also, in describing how particular types of people are likely to commit particular types of crime, his theory in many ways was the beginning of criminal profiling
W - scientific racism
distinct racist undertones within his work
many of the features he identified are most likely to be found among people with African descent
similarly his description of them being uncivilised and primitive would lend support to eugenic philosophies
controversial aspect which could have negative implications for certain people
W - contradictory evidence
compared 3000 criminals with 3000 non-criminals and found there was no evidence that offenders are a distinct group with unusual facial and cranial characteristics
questions his theory that criminals are physically different
