[citation needed] From 2001 to 2004, Nyhan (with Ben Fritz and Bryan Keefer) co-edited Spinsanity, a non-partisan watchdog of political spin that was syndicated in Salon.com in 2002 on-line and The Philadelphia Inquirer in 2004 in print and on the internet.
[citation needed] Nyhan co-authored the non-fiction political book All the President's Spin: George W. Bush, the Media and the Truth in 2004 along with Fritz and Keefer.
According to reviewer John Moe the book "detail[s] how Bush and company, more than any administration in history, cherry pick information that they find helpful, regardless of how representative it is of the overall truth, and then package it with a forceful and persistent presentation that eventually takes on the patina of reality.
In the Fall of 2011, upon completion of his term as a Robert Wood Johnson Scholar in Health Policy Research, Nyhan joined the faculty of Dartmouth College as an assistant professor of government.
[7] Nyhan's research as a political scientist has focused on the dynamics of scandals, misinformation, persuasion (in the face of misperception), social networks, and statistical methodology.
Nyhan, due to his background writing about such topics, (e.g. Spinsanity) refused and decided to terminate his relationship with The American Prospect (aka TAP).
[10] TAP editor Michael Tomasky said that "[t]he Prospect is hardly averse to criticizing liberal verities" ... but "there were a few posts in succession that struck us as either inaccurate or an effort to draw equivalencies where none existed."
