<p>The goal of this project is to conduct a close replication of the finding by Eskine (2012) that exposure to organic foods increases the severity of moral judgement and decreases pro-social behavior. </p> <p><a href="http://doi.org/10.1177/1948550616639649" rel="nofollow">1</a> Eskine, K. J., Wholesome Foods and Wholesome Morals?: Organic Foods Reduce Prosocial Behavior and Harshen Moral Judgments, Soc. Psychol. Personal. Sci. 4 (2012) 251–254.</p> <p>Current status: Complete. Manuscript describing this project is now published:</p> <p>Moery, E., & Calin-Jageman, R. J. (2016).

Ask MTurk sample to rate different food images for degree of organic/comfort food to recreate a stimulus set producing similar reactions as found in norming study by Eskine (2012). </li> <li>Review - Completed; Eskine has graciously reviewed replication checklist and provided original materials.</li> <li>Study 1 (aka Study 1a)- Completed. attempt an precise replication of Eskine (2012) with up to three indpeendent college-student populations. In the manuscript this study is described as Study 1a. </li> <li>Study 2 - Completed. Complete a large MTurk replication attempt with stringent quality controls to ensure the MTurk sample is naive to the materials, engaged, and appropriate for the study materials.</li> <li>Study 3 - Completed. A field study of moral judgement of those arriving at, departing from, or passing by an all-organic Farmer's market.</li> <li>Study 4 (aka Study 1b)- Completed. On the request of reviwers, we conducted a second close replication very similar to Study 1 but a) with at least 2.5x the original sample size, b) with a prosocial item even better matched to the original study (male faculty making the request rather than female undergrad and responses on scale of 0-30 minutes rather than 1-7 likert scale), and c) omitting the comfort group as non-essential. Note that in the manuscript this study is described as Study 1b.</li> </ul> <p><strong>Registration HIstory</strong> - First registration is on 6/5/2014; it locks in place analysis plan and materials prior to data collection for the online Study (Study 2 in the manuscript). - Second registration is 8/21/2014; it locks in place protocol, analysis plan, and materials prior to data collection for field study (now omitted from the manuscript). - Third registration is 9/16/2014; it locks in place protocol, analysis plan, and materials prior to data collection for the first direct replication (Study 1a in the manuscript). - Fourth registration is 10/20/2015; it locks in place protocol, analysis plan, and materials prior to data collection for the second direct replication (Study 1b in the manuscript, Study 4 in these online materials). </p>
