The trouble is, there’s a big element of “personal suggestion” in lots of “paid for” remedies.
No one (well, rarely anyone) will come in and say that the chiropractor they’re paying £40 a time for has done chuff all to help.
Why?
Because no one wants to admit to themselves, either knowingly or subconsciously, “gosh, I’ve been wasting £40 a week for 6 weeks, and yet am no different – aren’t I silly…”
The same happens to a degree if you tell someone that a pill you’re giving them will make them better – they don’t want to disappoint you so will ‘lie’ and say it helped.
Of course, this effect is strongest in subjective measures – it’s pretty hard to ‘think’ your blood pressure or cholesterol lower, but if I’m feeling tired, then pay £160 for some “magical shoelaces”, I can reassure myself that I’ve now more energy.
That’s not to say that if it helps someone feel better about themselves it’s inherently a ‘bad’ thing, but the marketing (lies) behind such claims can be dangerously misleading.
