Do you have any evidence that the result you found was the result this professor was citing?
It's not generally possible to gain an understanding of a field by "[looking] at some of those studies". This is why graduate students spend hours every week doing literature review. It's why news stations get an expert in the field to comment on a topic. Such experts can never be completely free of bias, but the idea that every expert should be coupled with someone with an opposing viewpoint (and if there's consensus in the field on the topic, who?) is ludicrous at best.
