IMHO it doesn't help that the middle class in California especially are health obsessed. Couple that with a kind of contrarian or rationalist/conspiratorial mindset in the public intellectuals(think Phil Dick or even Musk/Thiel -- I wanted to say not medically knowledgeable but you have got various Stanford profs too) -- you get healthcare very ripe.. eg cancer warnings on pretty much every consumable? "Science" is like a means to what an end!
This was one of the very stupid things about California. You'd have buildings with warnings that the upholstery in the chairs was manufactured using chemicals known to cause cancer, but have no idea what that actually meant. Are other chairs any safer? Am I at risk if they wash the fabric first? Is there any meaningful lower bound to the risk? What chemical is it, exactly?
