    • Large sample size with a match group meaning confident conclusions
    • Strict controls so can be repeated
    • Can be generalised as done on murders and none murders
    • High ecological validity as conducted in natural environment
    • Scientific so objective
    • Can find cause and effect as well controlled
    • Objective PET scans of brain activity, difficult to interpret accurately
    • Social factors not considered
    • Difficult to generalise to robbers and other criminals
    • Still dont know if murders become murders due to genetics or environmental factors
    • Expensive experiment
    • Only in early days of PET scans so hard to interpret
