One can be right for bad reasons.
But they're not wrong that the stuff coming out of the back of jet aircraft is changing the climate.
Small, localized weather engineering programs have long been real (cloud seeding), and planetary-scale climate engineering projects are now openly discussed by governments. E.g. https://www.epa.gov/geoengineering/about-geoengineering "Types of solar geoengineering techniques include: Stratospheric Aerosol Injection (SAI) – adding small reflective particles to the upper atmosphere (stratosphere) to reflect incoming sunlight. Sulfur dioxide (SO2), one of the types of chemicals considered for SAI, can chemically react in the stratosphere to form reflective sulfate aerosols."
The people who claim they're monitoring chemtrails aren't even watching aircraft which are deliberately dispensing payloads, because it just isn't that common in the first place (unless you go out and watch crop dusting, but then you can also just see the guy land, get out, and talk about it).
Hand washing prevents illness
COVID came from a lab, not a wet market
Hunter Biden laptop was real
And then a counter example of something broadly accepted but untrue. The humoral theory and blood letting, practiced for thousands of years. This is what killed George Washington.
Copernicus, but "close enough".
Yep. The planets do not, in fact, revolve around the Sun. They revolve around the solar system center of mass (barycenter). This is an error of about 0.25 degree viewed from Earth which was significant at the time.
> Hand washing prevents illness
Did the person who we credit for hand washing advocate for it because he was "crazy", or because he had a well-founded theory?
> COVID came from a lab, not a wet market
The lab-leak theory has not held up to scrutiny. It is considered refuted. Though IMO the initial backlash was excessive.
> Hunter Biden laptop was real
No one outside of politics said the laptop "wasn't real", many emails were cryptographically authenticated very early on. There was a great deal of concern by experts that a coordinated disinfo op was being played into the election. It was, though probably not with the involvement of foreign actors this time. Nothing about that laptop ended up being relevant to the Presidential candidate actually running for election.
> And then a counter example of something broadly accepted but untrue. The humoral theory and blood letting, practiced for thousands of years. This is what killed George Washington.
We're talking about examples of things a "crazy uncle" might believe that turned out to be true. These are just abandoned pre-scientific medical theories and treatments.
Not to anyone who is intellectually honest.
