supporting evidence for hostile attribution bias: Justye et al – 55 violent offenders shown pictures of ambiguous facial expressions – when they were compared with a non-aggressive control group, they were more likely to see the faces as angry - This shows that the theory can explain why some offenders are violent and so commit aggressive crimes as the research provides evidence that offenders interprets ambiguous faces as angry - However, research used a small sample size, meaning that the results may not be able to be accurately generalised to other criminals
