Arnold Kling quotes from security technologist Bruce Schneier’s latest book, Liars and Outliers:
In the real world, the knobs are poorly marked and badly calibrated, there’s a delay after you turn one of them before you notice any effects, and there’s so much else going on that it’s hard to figure out what the effect actually is.
which pretty much encapsulates my view of public policy. I’ve put the book on order. You’ll probably hear more about it from me later.
