It's not about autistic biases for me, at least not when the topic is the NHS. All of my father, uncle, aunt and other-half are doctors all of whom work for, at least in part, the NHS and are respectively an oncologist, dermatologist, GP and ob/gyn. As you might imagine, I spend quite a lot of time listening to them talk about the NHS, their particular trusts and their hospitals and the failings of all the above. All of them would much rather live here where you'll be looked after by the NHS, and can also have private care if you're willing to pay for it (though often the only difference is that you get a nicer room and shorter waits for non-emergency operations), than in the US where the patient is merely the mechanism through which you bill the insurance company.
