If you don't think or know that Chiropractors are real , then don't go to one. Go somewhere else.
Instead of placebos, which work, people have the choice of nutrition and good supplements, which work.
Pick and choose.
Test and test.
Find out what works.
"A BIG chunk"? How much ?
The first part isn't really up for debate, it's well-established that Chiropractic and "subluxation theory" are a pseudoscience.
That aside, you seem to have both snipped out, and ignored, the majority of my post which contained the pertinent info for this conversation.
Placebos "work" only within a very limited scope. And by "work", that means appease the patient until the ailment (which would've cleared up on its own) clears up. Thus the reason the primary use-case example of its usage is prescribing a placebo for a viral infection or for intangible ailments.
You won't find any physician worth their salt that's prescribing placebos for things like bacterial meningitis, coronary artery disease, major organ failure, epilepsy, etc... They'll do it when a patient comes in with a sinus infection (that's viral and will clear up on its own anyway, and doesn't respond to antibiotics) and is dead set on the idea "I need amoxicillin to fix this"
That's why context is important when having discussions about this.
There are some supplements that have benefits, but that's not what's being discussed here. The original conversation was about "Colon Cleanse" and "detox" supplements, which are overpriced, and offer no valid benefits. That's not the same as a person who's B-12 deficient taking a B-12 supplement from a reputable manufacturer.
This idea of "I'm going to do my own research, and make whatever decision I feel is best" is a particularly arrogant position with regards to complex topics like medical science. It's basically promoting the notion that
"With a relatively small amount of internet research, I'm just as qualified to assess this situation as a physician or researcher who's spent decades in the field, and thus, now my opinion on the matter is just as valid as well-supported peer reviewed research"
It's the same mentality that anti-vaccine proponents employ to try to make their case.
People certainly wouldn't take that approach for a wide variety of other complex topics. These aren't subjective matters like determining "what's my favorite color" or "which food tastes the best". This is an objective topic for which there are, indeed, right and wrong answers.
