Another problem on the internet (and beyond) is the existence of so-called think tanks and research organizations that don’t do actual bonafide and tested research or follow the scientific method, but instead arrange “evidence” that backs up the ideas they want to promote. Then politicians, unethical journalists, and others use their work to prop up their own ideas.
Here’s a good article from Wired about this.
One organization I’ve seen lately is the American College of Pediatricians–not to be confused with the legit American Academy of Pediatrics, which props up ideas for anti-LGBT groups. Here’s an article from Psychology Today about them and another from Patheos. They are extensively cited by groups listed as hate groups by the Southern Poverty Law Center. They should not be confused with the AAP if you see them mentioned online.
