This is also how people learn about the dangers of fan death, how carrots help improve your night vision, and that bulls are enraged by the color red.

Those examples seem super consequential compared to all the medical advancements that we got... I would gladly keep the medical advancements in exchange for turning off fans inside, eating more carrots, and avoiding red around bulls (or just avoiding bulls altogether; they stink).

Thankfully, humans like to try new things and then apply cause-and-effect reasoning to create good, new hypothesis (based by early citizen science evidence). I suspect that trait has massive benefits in our evolution. I hope people don't get put off by calls for "rigorous science" and keep experimenting on their own... and that the scientific establishment latches on to good ideas to do more rigorous studies! [The two aren't mutually exclusive! It's not zero sum!]
