The Chilean news media, in general, have fallen into the habit of interviewing political scientists when they need a comment on some event. This is, in general, a good thing. It sure beats those CNN types who interview each other. "Anderson, what is your view of the possible impact of the hurricane on corn futures?"
The problem is, that political scientists specialize in different areas, often having nothing to do with corn futures.
So as a general rule, I try to avoid commenting on corn futures, or other areas which are not somewhat related to my particular area of interest. As proof, here is an interview I gave on the situation in Greece.
