The authors of the article are academics (assistant professors, that is people with PhD in psychology and neuroscience) with connections to some very good research schools, as well as a psychiatrist with 35 years' experience. People who are dismissing this as "stuff on the internet" are not even thinking about the content.

You have to discriminate a bit with something as huge as the internet.
