Even though Star Wars is easily read as feminist for its time - and even for now, with Princess Leia's role - people wouldn't make a movie like that in 2016, where the guys are mostly the tough ones, and the women aren't in positions of authority.

Those who believe in climate change, as I do, I think it's also fair to say that they are more receptive to confirming evidence than disconfirming evidence. They happen to be right, but their motivations are in play also.

Star Wars may be kind of a cartoon, but the original trilogy depicts a political paralysis which breeds an interest in a strong leader who will make a significant break with the past. And Hillary Clinton is a person - whether you like it or not - of extraordinary experience. I don't know if we ever had a presidential candidate with that level of political experience. There's no learning curve for her. And that, in some periods, would be a huge plus. In the end, I think it will be a significant plus for her now.

Rumors are nearly as old as human history, but with the rise of the Internet, they have become ubiquitous. In fact we are now awash in them. False rumors are especially troublesome; they impose real damage on individuals and institutions, and they often resist correction. They can threaten careers, policies, public officials, and sometimes even democracy itself.

A lot of people are focused on climate change as a defining challenge of our time. A lot of people think it is a non-problem, at least in the United States.

I have argued in favor of a reformulation of First Amendment law. The overriding goal of the reformulation is to reinvigorate processes of democratic deliberation, by ensuring greater attention to public issues and greater diversity of views.

And so it's no surprise that people who object to the death penalty on pure moral grounds also think it has no deterrent effect, and people who like the death penalty on grounds of retribution tend to think it has deterrent effects. They like that, and they believe that. I think with climate change we're seeing very much the same thing where those who deny climate change, they don't like that, and they don't believe it.
