Hall (July 2, 1945 – January 11, 2023) was an American family physician, U.S. Air Force flight surgeon, author, science communicator, and skeptic.

After retiring as a colonel in the U.S. Air Force, Hall was a frequent speaker at science and skepticism related conventions in the US and around the world.

[2] Sampson encouraged Hall to write an article for the Scientific Review of Alternative Medicine[8] testing so-called "Vitamin O" products she had seen advertised in the mail.

[10][11] Hall spoke with Michael Shermer at The Amazing Meeting in 2005 about the book The God Code and he asked her write a review of it for Skeptic magazine.

As a female physician, air force officer, pilot and flight surgeon, she was a minority in several respects, and encountered prejudice.

[7] Starting in the January 2010 issue, Hall had a regular 250-word column debunking common health myths in O, The Oprah Magazine.

[23] On August 21, 2010, Hall was honored with an award recognizing her contributions in the skeptical field, from the IIG during its 10th Anniversary Gala.

[25] In 2015 she published a YouTube lecture series entitled "Science Based Medicine", commissioned by the James Randi Educational Foundation.

"[29] She criticized the U.S. Army for its use of acupuncture: "the idea that putting needles in somebody's ear is going to substitute for things like morphine is just ridiculous.

[35] Hall had previously coined the term "tooth fairy science" to refer to studying a phenomenon before establishing its existence.

"[38][3] She elaborates, "Once you have located the opposing arguments you can evaluate which side has the most credible evidence and the fewest logical fallacies.

[40]On June 15, 2021, Hall published a book review of Irreversible Damage in Science-Based Medicine (SBM) stating that the book "brings up some alarming facts that desperately need to be looked into", that the affirmative care model for gender dysphoria in children "is a mistake and a dereliction of duty", and that the current political climate has made scientific study of these matters nearly impossible.

[41][42] Within two days, the review was removed and replaced with a retraction notice authored by Steven Novella and David Gorski.

[41] Science-Based Medicine also published a series of articles from doctors specialising in LGBTQ+ health care, which were critical of the book and Hall's positive review.

[50][51][52][53] Hall's review of Shrier's book was republished at Skeptic.com, and an updated version that responded to the critiques was published on her personal website.
