I’m no microbiologist either. I can’t cite a paper to tell me there’s no risk of heart disease from pumping my own gasoline. But I also don’t have a model of the world that suggests any connection between pumping gasoline and heart disease, so I don’t worry about it. Most things don’t cause most other things. So just on priors, there’s no reason to worry about this.
