I agree, it's a great magazine. But don't forget that even the Economist is only providing a shallow overview of any given topic (despite the apparent depth); has a specific partisan viewpoint / world philosophy; and is frequently wrong.

Most people know that at an intellectual level, of course. But it's all too easy to read something like an Economist article and come away thinking "oh, I learned a lot / have a decent understanding of this issue". A lot of that comes down to the editorial style and self-assured tone of the writing. It helps to remember that even something like the Economist is largely written by people in their mid-20s with no particular expertise, and edited by people who may be older and wiser but also cover many different topics.
