Unfortunately, this is exactly what I am objecting to. I agree it is a good heuristic to receive information. This is not what the post is about; it is not about ceteris paribus. Emphasis added:

More information is never a bad thing. ...The second of these is always at least as large as the first.

In a post claiming to offer proofs, I take these universal qualifiers at face value. They may be true in the simplified model. They are not true in many other models, one of which I have linked.

Since I was downvoted so very severely, I'll add another link, an entire paper by Nick Bostrom on all the kinds of information which receiving can hurt you: http://www.nickbostrom.com/information-hazards.pdf
