I find the trend towards quick character assassination (rather than looking at the facts) quite annoying. We see it in climate debate, for example, way too often.
That's rationalization instead of rationality. Rationality dictates discovering the facts BEFORE you reach the conclusions.
Maybe an adversarial method would be a better way of addressing these issues in practice, but only when we're responsible enough to read both sides.
Also, it's intellectually dishonest to pick your conclusions first and find the facts later. Even if CATO finds good facts (I'm sure they do), there is most definitely something "wrong with" them.
I haven't real the full paper yet, but the sourcing is impeccable, using government statistics and peer-reviewed papers rather than private surveys or anecdotal evidence.
I think "he uses statistics as a drunk man uses a lightpost, for support rather than illumination" is apropos here.
