Deception in experiments

Link here

A joint letter from the presidents of Stanford University and Dartmouth College will be sent to nearly 100,000 Montana voters to apologize for an experiment by three political-science professors at the two institutions. The letter comes after voters and state officials objected to a mailer, sent by the professors, that featured the state’s official seal and offered information about the political leanings of candidates for the state’s Supreme Court as part of an attempt to see whether such information would alter how Montanans voted.

The article is interesting and the issues aren't confined to political science.  I have a paper that will be published soon examining how economists view and define deception in economic experiments.  Once the article is posted online I will link to it here.
