Shanto Iyengar is a professor of communication at Stanford University and director of Stanford's Political Communication Lab. He's one of the senior scholars in the field of political communication and is a leading researcher in the areas of framing and political advertising respectively.

He joined the Washington Post today for an online conversation with readers about the McCain and Obama advertising strategies. In his answers you will find many of the same themes and conclusions raised at this blog, principles that as I have detailed before, not only apply to understanding the communication dynamics of the 2008 election race but also science policy debates more broadly. Indeed, when it comes to public opinion and media influence, there is nothing essentially unique about these science debates from other political controversies.

The online conversation is well worth reading. Check it out here.
