See also the [erratum][7].**<br /> <img src="https://osf.io/9fs5i/download" /> 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="http://peoplescience.org/sites/default/files/OppenheimerMeyvisDavidenko.2009.pdf">Instructional manipulation checks: Detecting satisficing to increase statistical power</a> (Oppenheimer et al., 2009) <a href="http://psych.hanover.edu/classes/cognition/papers/tversky81.pdf">The framing of decisions and the psychology of choice</a> (Tversky & Kahneman, 1981) <a href="http://psycnet.apa.org/psycinfo/1996-24980-001">Measures of anchoring in estimation tasks</a> (Jacowitz & Kahneman, 1995) <a href="http://journal.sjdm.org/9609/jdm9609.pdf">The retrospective gambler’s fallacy: Unlikely events, constructing the past, and multiple universes</a> (Oppenheimer & Monin, 2009) <a href="http://connection.ebscohost.com/c/articles/5414342/response-scales-effects-category-range-reported-behavior-comparative-judgments">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="https://pantherfile.uwm.edu/suelima/labreport1/rugg1941.pdf">Experiments in wording questions: II</a> (Rugg, 1941) <a href="http://psycnet.apa.org/psycinfo/1937-04240-001">Prestige, suggestion, and attitudes</a> (Lorge & Curtiss, 1936) <a href="http://pss.sagepub.com/content/early/2011/07/08/0956797611414726">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="http://www.ncbi.nlm.nih.gov/pubmed/22774789">Mere exposure to money increases endorsement of free-market systems and social inequality</a> (Caruso et al., 2012) <a href="http://www.sciencedirect.com/science/article/pii/S0022103110001307">Elaboration enhances the imagined contact effect</a> (Husnu & Crisp, 2010, Study 1) <a href="http://www.ncbi.nlm.nih.gov/pubmed/12088131">Math = Male, Me = Female, therefore Math ≠ Me</a> (Nosek, Banaji, & Greenwald, 2002) [1]: https://osf.io/wx7ck/wiki/home/ [2]: https://osf.io/9fs5i/ [3]: https://osf.io/pqf9r/ [4]: https://osf.io/abesq/ [5]: https://osf.io/ebmf8/ [6]: https://openscienceframework.org/project/WX7Ck/files/ [7]: https://psycnet.apa.org/record/2019-34530-002 [8]: https://psycnet.apa.org/record/2019-34530-002 [9]: https://osf.io/y36m8/ [10]: https://osf.io/xvpu3/ [11]: https://osf.io/t6a3n/ [12]: https://osf.io/cmi6b/ [13]: https://osf.io/pqf9r/ [14]: https://osf.io/7rzan/ [15]: https://osf.io/rn4ue/ [16]: https://osf.io/v89rn/
