alt Hacker NewsChiropractory is another pseudoscience that started early and has been surprisingly resilient in spite of the lack of evidence. I was flabbergasted when I learned in my 30s that this was a made up medicine by an OG antivaxxer and magnetic medicine proponent due to the fact that insurance would still pay for it when I was a kid at least, and real doctors still recommended it on occasion.[1][2]

The problem with making claims about the chiropractic practices is that it spans such a huge range of "absolute bullshit" to "physically grounded adjustments". Joints and vertebrae (especially) really can be out of alignment, and you can absolutely see that on imaging. Muscles in constant tension can be self-reinforcing in ways that don't easily correct themselves without an external force. My wife has significant back issues as a result of various injuries -- one leading to an SI joint that frequently pops out of place, one due to an injury that fractured most of the spinal processes -- and you can absolutely feel the "pop" when an adjustment helps something slide back in place. This is validated by imaging and sports medicine, not just chiropractic quacks.
At the same, adjusting your back isn't going to cure your cancer, no matter what idiots with fake degrees say.
The challenge is that the latter is just as stupid as homeopathy, but whereas homeopathy really has no redeeming qualities beyond the placebo effect, at least chiropractic practices actually do sometimes have groundings in reality.
