Trust, but verify

In [a comment]( over at, a reader pointed out that it’s a good idea to verify not just SSL certificate, but also doctors, mechanics, etc. He says, “it’s simply a requirement of a healthy society that it’s citizens have a healthy skepticism and be willing to put the effort into understanding what is going on around them. It’s not that you don’t trust them. Its that you do what you can, in your limited way, to make sure that you can trust them.”
