Dave Weigel has some fun with credulous journalists who are sure that Paul Ryan must be a Very Serious Wonk because — wait for it — he uses PowerPoint. With pie charts!

This is really amazing.

Look, I know wonks. Ryan is not a wonk. Yes, he likes charts and slides. But he very clearly doesn’t know what his numbers actually mean. When the famous plan was unveiled, it was quite clear that he never even realized that the Heritage projection of his plan’s impact made a completely ridiculous assertion about what would happen to unemployment. Nor did he realize that his assumptions about discretionary spending would require cutting such spending — including defense! — to levels not seen since Calvin Coolidge.

One question one might ask is whether Ryan is aware that he isn’t actually a wonk, that he just plays one on TV. Maybe not; some of what he says suggests the Dunning-Kruger effect at work,: he may be so innumerate that he doesn’t realize that he has no idea what the numbers he throws around mean. And after all, why would he, given all the praise he’s received for putting up a line graph or pie chart here and there?

If the fate of the republic weren’t at stake, it would be funny — and painfully embarassing.
