Marvin Wolfgang on Kleck’s DGU survey

This is untrue. Wolfgang writes:

"The usual criticisms of survey research, such as that done by Kleck and Gertz, also apply to their research. The problems of small numbers and extrapolating from relatively small samples to the universe are common criticisms of all survey research, including theirs. I did not mention this specifically in my printed comments because I thought that this was obvious; within the specific limitations of their research is what I meant by a lack of criticism methodologically." (J of Criminal Law and Criminology 86:2 p617-8)

One of the limitations of survey research that Wolfgang considered too obvious to be necessary to point out is there is no guarantee that all respondents told the truth. Mr Schulman is perhaps unaware of this fact.
