It is anti-intellectual to blather on over pages and pages, trying to tell people how to live their lives without giving any information to show if ones statements are correct or not.
"Intellectual" is, for some reason, accepted in some circles as meaning longwinded unscientific musings, to which whole university departments are devoted. That does not mean it is not an utter waste of time and effort, that would be better spent on measuring things and giving advice that is actually shown to improve people's lives.
