Logical fallacies are viewpoints brought up during arguments which appear logical on the surface, but when you dig a little deeper are in fact mostly unfounded. One common fallacy is the appeal to authority, where you assume that just because someone is an "authority," that they have to be right. For example, "Pope Urban VIII said that Galileo's views were wrong, so since I trust the Pope I'm going to agree with the Pope and say that the universe is actually geocentric." Sometimes the flaw is that the "authority" isn't actually authoritative in the topic in question - the Pope isn't an astronomer, the President of the US isn't a meteorologist, etc. But even if the "authority" is actually an authority, that doesn't make him/her automatically correct. Even authorities make mistakes - look at Tycho Brahe for example. This is also the entire point of peer reviewed journals, to give the authorities the chance to duke it out.
So that said, when the NY Times Magazine devotes a 28-screen-long article to singing Freeman Dyson's laurels as a motivation for us to listen to his arguments about CO_2 levels, I find myself quite disappointed. Dyson is an authority on quantum physics and sci-fi concepts (such as the Dyson sphere, which led to Larry Niven's Ringworld concept/series); he is NOT an authority on environmental science. I don't care how many people think he's a genius, he isn't a genius in this field. And even if he were, even authorities can make mistakes. It is NOT appropriate for the NY Times to promote an individual's ideas based solely upon that individual's reputation. If the article were billing itself as a biography of Dyson's life, it could be an excellent one, but the article is trying to give us a view of Dyson's ideas and as such it is a remarkably poor one.
I guess in the end by expecting the NY Times to live up to its reputation, I too am guilty of putting too much faith in authority.
