I'm sorry, but this just sounds like the "Forbidden Knowledge" Trick (think of it as a cousin to Galileo's Gambit)
(1) In your most authoritative tone, state something as fact without citation.
(2) Say major testing-based orgs are never going to give you the real truth.
We have a system for knowledge. I think it is an absurd mess, but I trust it way more than anything presented in the format you’ve just used.
Maybe this is just a formatting issue and you have credible information to back your claim, but as it is currently presented it does not pass the sniff test.
Heck, you still are; "Read other people's experiences and feel your own body." That is a mode of interacting with the external world and processing knowledge. You didn't even suggest I do it; your sentence was a directive. Furthermore, it was packaged in that cool detached "above it all" way that humans sometimes use to convince others.
It's good/okay/whatever to try and sell people on your worldview. I was engaged and conversing that is the social cue to do so. The fact that you didn't convince me is whatever on the internet. But playing it off like you weren't doing that... why?
I'm pretty sure the number of times someone has been convinced on the internet wouldn't even correctly round in IEEE double-precision floating point.
Sitting on ass does.
If you are looking to the landing page of any of those major bodies to figure out how to fuel your body, good luck.
