Problem: Cass Robert Sunstein FBA (born September 21, 1954) is an American legal scholar, particularly in the fields of constitutional law, administrative law, environmental law, and law and behavioral economics, who was the Administrator of the White House Office of Information and Regulatory Affairs in the Obama administration from 2009 to 2012. For 27 years, Sunstein taught at the University of Chicago Law School. Sunstein is the Robert Walmsley University Professor at Harvard Law School. He is Honorary Doctor at Copenhagen Business School.

Sunstein co-authored a 2008 paper with Adrian Vermeule, titled "Conspiracy Theories," dealing with the risks and possible government responses to conspiracy theories resulting from "cascades" of faulty information within groups that may ultimately lead to violence. In this article they wrote, "The existence of both domestic and foreign conspiracy theories, we suggest, is no trivial matter, posing real risks to the government's antiterrorism policies, whatever the latter may be." They go on to propose that, "the best response consists in cognitive infiltration of extremist groups", where they suggest, among other tactics, "Government agents (and their allies) might enter chat rooms, online social networks, or even real-space groups and attempt to undermine percolating conspiracy theories by raising doubts about their factual premises, causal logic or implications for political action." They refer, several times, to groups that promote the view that the US Government was responsible or complicit in the September 11 attacks as "extremist groups."  The authors declare that there are five hypothetical responses a government can take toward conspiracy theories: "We can readily imagine a series of possible responses. (1) Government might ban conspiracy theorizing. (2) Government might impose some kind of tax, financial or otherwise, on those who disseminate such theories. (3) Government might itself engage in counterspeech, marshaling arguments to discredit conspiracy theories. (4) Government might formally hire credible private parties to engage in counterspeech. (5) Government might engage in informal communication with such parties, encouraging them to help." However, the authors advocate that each "instrument has a distinctive set of potential effects, or costs and benefits, and each will have a place under imaginable conditions. However, our main policy idea is that government should engage in cognitive infiltration of the groups that produce conspiracy theories, which involves a mix of (3), (4) and (5)."  Sunstein and Vermeule also analyze the practice of recruiting "nongovernmental officials"; they suggest that "government can supply these independent experts with information and perhaps prod them into action from behind the scenes," further warning that "too close a connection will be self-defeating if it is exposed." Sunstein and Vermeule argue that the practice of enlisting non-government officials, "might ensure that credible independent experts offer the rebuttal, rather than government officials themselves. There is a tradeoff between credibility and control, however. The price of credibility is that government cannot be seen to control the independent experts." This position has been criticized by some commentators who argue that it would violate prohibitions on government propaganda aimed at domestic citizens. Sunstein and Vermeule's proposed infiltrations have also been met by sharply critical scholarly critiques.

What year was this

Answer with quotes: 2008

Question:
Hiawatha (also known as Ayenwatha, Aiionwatha, or Haien'wa'tha [ha.je?.wa?.tha] in Onondaga) was a pre-colonial Native American leader and co-founder of the Iroquois Confederacy. Depending on the version of the narrative, he was a leader of the Onondaga and the Mohawk, or both. According to some versions, he was born an Onondaga, but adopted into the Mohawk. Hiawatha was a follower of the Great Peacemaker (Deganawida), a Huron prophet and spiritual leader who proposed the unification of the Iroquois peoples, who shared common ancestry and similar languages.
In attempting to date the Great Peacemaker and Hiawatha, focus has come to an incident related to the founding of the Iroquois Confederacy, their lifework. One rendition of the oral history eventually written down by scholars involves a division among the Seneca nation, the last nation to join the original confederacy. A violent confrontation began and was suddenly stopped when the sun darkened, and it seemed like night. Scholars have successively studied the possibilities of this being a solar eclipse since 1902 when William Canfield wrote Legends of the Iroquois; told by "the Cornplanter". Successive other scholars who mention it were (chronologically): Paul A. W. Wallace, Elizabeth Tooker, Bruce E. Johansen, Dean R. Snow, Barbara A. Mann and Jerry L. Fields, William N. Fenton, David Henige, Gary Warrick, and Neta Crawford.  Since Canfield's first mention, and the majority view, scholars have supported the 1451 AD date for the plausible solar eclipse mention. Some argue it is an insufficient fit for the description and favor 1142 AD while a few question the whole idea.  Archaeological supporting arguments have progressed. In 1982 Dean Snow considered the mainstream view of the archaeology not to support any dates for an eclipse before 1350 AD (thus ruling out the 1142 AD date.) By 1998 Fenton considered an earlier eclipse than the 1451 AD majority view unlikely but possible as long as it was after 1000 AD - a window that allows the 1142 AD date. By 2007/8 reviews considered an 1142 AD eclipse as clearly possible even if most still supported 1451 AD as the safe choice.
