I never claimed this was a scientific study. It was an observation repeated over time. That is empirical in the plain meaning of the word.
Criticizing it for “not being scientific” is irrelevant, I didn’t present it as science. Are people only allowed to share experiences here if they come wrapped in a peer-reviewed paper?
If you want to debate the substance of the observation, happy to. But don’t rewrite what I said into a claim I never made.
