I'm not talking about rationalists, who can be real asses, but a basic level of reason-based interaction with the world.
Epsom salts are NOT absorbed through the skin. Think about it for a minute! When you sweat does it get absorbed back in? If you sit in the tub does your body absorb water into the bloodstream? Of course not.
GMOs are not inherently bad or dangerous. Natural is not inherently good. Extracts that kill things in cell culture are not automatically good cancer treatments. Essential oils don't do anything except smell nice.
The water is tested yearly and they send us the report. Three cases of cancer on one street are not a cluster, and probably not due to arsenic. Almost nothing has a 100% penetrance on cancer causing.* In fact, almost nothing has 100% penetrance on anything, aside from some nasty genetic diseases.
Basic logic is a thing. Proof by counterexample. Reasoning from principles. The difference between necessary and sufficient conditions. Whyyyy are people so bad at basic logic?

* High dose radiation but less than the lethal dose, possibly. Maybe drinking some really bad chemicals. Asbestos?
