Media Bias Fact Check selects and publishes fact checks from around the world. We only utilize fact-checkers that are either a signatory of the International Fact-Checking Network (IFCN) or have been verified as credible by MBFC. Further, we review each fact check for accuracy before publishing. We fact-check the fact-checkers and let you know their bias. When appropriate, we explain the rating and/or offer our own rating if we disagree with the fact-checker. (D. Van Zandt)

| MISLEADING | Claim by Gary Brecka: “Fluoride is a neurotoxin. Studies link it to lower IQ in kids, thyroid dysfunction, and weakened bone density.”
Science Feedback rating: Misleading (Studies cited by anti-fluoridation activists involve fluoride levels far higher than those used in community water systems. At recommended levels, no credible evidence shows fluoride lowers IQ, harms the thyroid, or weakens bones. Water fluoridation remains a proven public health measure to prevent tooth decay.)

But it was not the only state to do so. Six other states lost population since the 2020 census, and two other states have seen a decrease since the 2023 population estimate.) |
