“…It should be noted that, while MTurk has been increasingly used in political science (e.g., Ahler ; Arceneaux ; Berinsky, Huber, and Lenz ; Crawford and Pilanski ; Doherty ; Eriksson and Funcke ; Fausey and Matlock ; Glynn ; Grimmer, Messing, and Westwood ; Grose, Malhotra, and Van Houweling ; Huber, Hill, and Lenz ; Huber and Paris ; Kriner and Shen ; Kriner and Shen ; Lawson et al ; Montgomery and Cutler ; Testa, Hibbing, and Ritchie ; Thibodeau et al ) and has been validated in other disciplines insofar as providing results similar to those of more conventional surveys and laboratory experiments (e.g., Buhrmester, Kwang, and Gosling ; Casler, Bickel, and Hackett ; Horton, Rand, and Zeckhauser ; Mason and Suri ; Paolacci, Chandler, and Ipeirotos ; Sprouse ), the usage of MTurk does remain somewhat controversial. Frequently targeted are the facts that the demographics of MTurk—and thus the demographics of samples recruited from the service—differ from national demographics in important ways (e.g., Casler, Bickel, and Hackett ), that it is often too easy for respondents in foreign countries to circumvent limitations requiring respondents be from the United States (e.g., Shapiro, Chandler, and Mueller ), that respondents respond to the financial incentives provided by each task by paying insufficient attention to the tasks at hand (e.g., Crump, McConnell, and Gureckis ), and that respondents may repeat the same or similar studies, thus reducing the effectiveness of experimental manipulations (e.g., Chandler, Mueller, and Paolacci ).…”
