Much like the previous information you shared from the Gatway Pundit about the underperformance of Joe Biden in major cities compared to the two previous Democratic presidential candidates, the Pundit again does a poor job of accurately reporting facts. This time, the author of the article doesn't even make it out of the headline without messing up the facts.
This is not the result of a, "Stanford Study." This is a hypothesis written by (I believe) a doctor at the Palo Alto V.A. The title of the doc's article even tells you it's not a report by including the phrase, "A Hypothesis," in its title.
The next paragraph proceeds to label it a peer-reviewed study. It is not. You can figure that out from reading the entire three page (not including end notes) piece. If you don't want to do all that reading or you don't know how to identify the signs of something that has not been peer-reviewed, you can just look up the online journal that published it.
According to it's about page, Medical Hypothesis, "will publish interesting and important theoretical papers that foster the diversity and debate upon which the scientific process thrives. The Aims and Scope of Medical Hypotheses are no different now from what was proposed by the founder of the journal, the late Dr David Horrobin." It goes on to say that it's review standard is the editor, who, based on the piece cited in the Pundit, apparently doesn't correct spelling errors. Since the journal claims to have the same goals it always had, it should be pointed out that it once published a hypothesis (just like this one, not peer-reviewed but evaluated by the editor) that claimed HIV doesn't cause AIDS. That was in 2009, by the way.
All that said, I do agree with some of his theories around the possible psychological side effects of masks. On the other side, if the masks sole purpose, as many suggest, is to give people a false sense of security, it's strange they would cause stress, fear or even moodiness. If anything, it would probably alleviate some of those emotional reactions.
It's interesting that he placed a third category of potential health consequences (he even labels them as potential) from the potential physiological and psychological effects of the masks, when there is such a lack of data to support it. He includes accelerated aging and premature mortality. What possible research could have been done in the past year to show that?
There may be a lot in the article that turns out to be true. As of now, however, it reads like something that was written with the intent of landing an expert-spot on Tucker Carlson and published by an online journal that, by it's own admission, exists to publish unverified material that will spark debate.
