Research on the public’s views on sentencing can play a valuable role in the policy process. However, it must be recognised that ascertaining and measuring public opinion is very difficult to do. Unless research is well-designed and methodologically rigorous then the results are almost certain to be flawed. Any general assessments of the public’s view of sentencing policy across all offences should be balanced against analysis and engagement of public opinion and understanding which, where possible, focuses on specific offences or offence types.
