The CDC Repeatedly And Purposefully Put Out Misleading, Low Quality Studies To Push Masks
MMWR’s Used To Launder Misinformation To The Media
Much of the damage caused by the CDC was the result of the reliance of government figures and media outlets on their work.
Politicians referenced the CDC while mandating masks, with former Nevada Governor Steve Sisolak specifically setting targets for
mask usage based on the CDC’s research.
Legacy media outlets would purposefully and breathlessly report on their latest releases, regardless of how profoundly dishonest or misleading their messaging turned out to be.
An already discredited agency hits a new low

Vinay Prasad, Tracy Høeg and Alyson Haslam went to work dissecting just how bad the CDC’s research was, laundered through propaganda-esque
MMWR releases.
And unsurprisingly, their conclusions showed just how politicized and unreliable the CDC was during the pandemic. Particularly on masking.
Objective: To describe and evaluate the nature and methodology of the reports and appropriateness of conclusions in MMWR pertaining to masks. Design, Setting and Participants: Retrospective cross-sectional study of MMWR publications pertaining to masks from 1978 to 2023. Main outcome measures: Study date, design, disease focus, setting, population and location. Whether the study was able to assess mask effectiveness, if results were statistically significant, if masks were concluded to be effective, if randomized evidence and/or conflicting data was mentioned or cited, if causal statements were made about effectiveness, and, if so, whether they were appropriate.
Seventy-seven studies met the criteria for inclusion. But in what perhaps is the clearest indicator of how hopelessly unusable mask research actually is, 0/77 were randomized trials.
Not one.
Instead, the CDC released 22 studies that contained no comparative group at all, and over 70% inappropriately used “causal language” despite having only 11 of the 77 studies claim statistically significant results.
Essentially, the CDC’s MMWR releases overstated their conclusions by using causal language to suggest that masks were effective, when the underlying methodology and results did not support that assessment.
The studies used by the media and politicians to justify their mandates and support were based on low quality evidence with unsupported conclusions.
MMWR publications pertaining to masks drew positive conclusions about mask effectiveness over 75% of the time despite only 30% testing masks and <15% having statistically significant results. No studies were randomized, yet over half drew causal conclusions. The level of evidence generated was low and the conclusions drawn were most often unsupported by the data.
There should be no doubt that the CDC purposefully promotes research that supports its conclusions, no matter how inaccurate. During their research, Prasad and Høeg found that 91% of the 77 MMWR releases were written by at least author associated with the CDC.
The CDC obtains research from authors associated with the organization then uses it to launder unsupported conclusions through a willing media.
No matter how much respect you’ve lost in the CDC over the past few years, it’s truly not enough.
But it gets worse.
Nearly 100% of studies did not reference conflicting data that would necessarily indicate the limited value of their conclusions.
75.3% inappropriately claimed masks were effective, despite the lack of supporting evidence.
And over 53% inappropriately claimed that their research established a causal link between masks and the claimed results.
The detailed summary provided shows how remarkably biased the conclusion statements were, relative to their actual provided evidence.
What makes this even more infuriating is that the CDC undoubtedly knew that their MMWR releases failed to prove that masks worked, yet were ensured that media outlets would blindly repeat their unsupported conclusions regardless.
Dishonest conclusions used dishonestly, to promote an unjustifiable policy goal.
Just one of all 77 studies included in the examination appropriately used casual language. Just one.
And that was a mannequin study.
“In another school masking study, errors in data analysis and methodology, which normally would warrant retraction, were not addressed by the journal.”
Høeg and Prasad also highlighted one of the CDC’s most inexcusable errors: promoting the unimaginably bad cloth masking study from California that used non-statistically significant results to misinform readers and the media that wearing masks would result in an 80% decrease in the risk of contracting COVID.
And in typically understated fashion, they explain that the consistently poor work displays pro-mask bias.
Taken together, the absence of randomized data, the lack of acknowledgment of conflicting or randomized data on mask efficacy, and the tendency to conclude masks are efficacious either without any, or sufficient, data to make causal claims, is suggestive of bias within the journal.
But their important work goes much deeper than being “suggestive of bias.”
It’s proof positive of the CDC’s disastrous ideology, their commitment to politics over evidence, and how corrupt the research process is in practice.
What should be the nation’s premier health agency had an agenda to promote masks, so they mobilized a group of researchers who rely on the CDC for funding and support to conduct desperate, low quality studies to justify their ideological needs. And the researchers were happy to comply.
The CDC then created easily digestible graphics meant to be laundered through an ideologically agreeable media that promoted unsupported conclusions.
Politicians relied on those graphics, Twitter “experts” shared studies, school administrators mandated masks - all based on low quality evidence they didn’t actually read.
And the CDC knew it, and encouraged it to continue.
The amount of harm, damage and permanent societal changes they introduced based on purposefully poor research is incalculable.
All while ignoring the importance of actual high quality research.
