Petitions should not be signed by philosophers, who have an obligation to focus on the strengths and weaknesses of the arguments instead of appealing to the majority opinion in support of any claims.

For an argument on behalf of this claim, please see Agnes Callard, "Why Philosophers Shouldn’t Sign Petitions", New York Times, August 13, 2019, https://www.nytimes.com/2019/08/13/opinion/philosophers-petitions.html
