尽管复制是科学的核心原则，但直接复制在心理学中很少见。这项研究测试了36个独立样本的13个经典和当代影响的可复制性的差异，总计6,344名参与者。在骨料中，10个效果始终如一地复制。一种效果 - 想象的接触减少偏见 - 对复制性的支持较弱。两种效果 - 影响保守主义和货币启动影响系统理由的旗帜启动 - 没有复制。我们比较了实验室与在线或美国与国际样本预测效果的幅度等条件。总的来说，他们没有。这一小样本效应的结果表明，可复制性更依赖于效果本身，而不是对样本和用于研究效果的设置。
Although replication is a central tenet of science, direct replications are rare in psychology. This research tested variation in the replicability of 13 classic and contemporary effects across 36 independent samples totaling 6,344 participants. In the aggregate, 10 effects replicated consistently. One effect - imagined contact reducing prejudice - showed weak support for replicability. And two effects - flag priming influencing conservatism and currency priming influencing system justification - did not replicate. We compared whether the conditions such as lab versus online or US versus international sample predicted effect magnitudes. By and large they did not. The results of this small sample of effects suggest that replicability is more dependent on the effect itself than on the sample and setting used to investigate the effect.
