There’s nothing in US journalism anything like Ben Goldacre’s Bad Science columns for the Guardian. Check them out. The point of the column is to tear into bad science and especially bad science reporting. He writes with humor (or is it humour?) and attitude. He’s not afraid to get a bit technical (although with great clarity, I think) when the situation calls for it.
In a way, he has nothing to complain about: he lives in a country with both the Guardian and the Economist, which have much better science reporting than anything we’ve got here.
