See also the [erratum][7].**<br /> <img src="" /> Notes: **Erratum** correcting the effect size for allowed/forbidden (among other issues) is [published here][8]. **Updated stats** for [ML.web.Supplement.pdf][9] made on 10/19/2017 fixing incorrect numbers for Anchoring and Adjustment. Thanks to Uri Simonsohn for discovering these errors. Notes: “X” indicates the effect sizes obtained in the original studies. Large circles represent the aggregate effect sizes obtained across all participants. Error bars represent 99% noncentral confidence intervals around the effects. Small circles represent the effect sizes obtained within each site (grey and green circles for US and international replications, respectively). **Index:** - [Methods and Materials][10] used in the replications. - [Mock session videos][11] of experimental sessions. - [Site and Sample Characteristics][12] documenting the context of the different data collection sites. - [Open Datasets][13] - [Analytic scripts and output][14] - [Overall summary results, and results per each site][15]. - [Our response to the commentaries][16], and data/results from follow-up investigations prompted by the commentaries (mostly relating to Anchoring and Adjustment). **Links to original articles that provide the studies for this replication effort:** <a href="">Instructional manipulation checks: Detecting satisficing to increase statistical power</a> (Oppenheimer et al., 2009) <a href="">The framing of decisions and the psychology of choice</a> (Tversky & Kahneman, 1981) <a href="">Measures of anchoring in estimation tasks</a> (Jacowitz & Kahneman, 1995) <a href="">The retrospective gambler’s fallacy: Unlikely events, constructing the past, and multiple universes</a> (Oppenheimer & Monin, 2009) <a href="">Response scales: Effects of category range on reported behavior and comparative judgments</a> (Schwarz et al., 1985) The current status of American public opinion (Hyman & Sheatsley, 1950) <a href="">Experiments in wording questions: II</a> (Rugg, 1941) <a href="">Prestige, suggestion, and attitudes</a> (Lorge & Curtiss, 1936) <a href="">A single exposure to the American flag shifts support toward Republicanism up to 8 months later</a> (Carter et al., 2011; Study 2) <a href="">Mere exposure to money increases endorsement of free-market systems and social inequality</a> (Caruso et al., 2012) <a href="">Elaboration enhances the imagined contact effect</a> (Husnu & Crisp, 2010, Study 1) <a href="">Math = Male, Me = Female, therefore Math ≠ Me</a> (Nosek, Banaji, & Greenwald, 2002) [1]: [2]: [3]: [4]: [5]: [6]: [7]: [8]: [9]: [10]: [11]: [12]: [13]: [14]: [15]: [16]:
