Eh, I find the lack of objectivity in sample selection and the subjectivity in response categorization in the research study equally remarkable.

The journal which this study was published in has an impact factor of 0.05 which is very very low. I'm not normally one to tout credentials, but as it stands the credential of the journal is consistent with the lack of quality of the research. This seems like the kind of journal that could easily get targeted by Sokal hoaxes.
