Williams and Bargh (2008) reported that holding a hot cup of coffee caused participants to judge a person’s personality as warmer and that holding a therapeutic heat pad caused participants to choose rewards for other people rather than for themselves. These experiments featured large effects (r = .28 and .31), small sample sizes (41 and 53 participants), and barely statistically significant results. We attempted to replicate both experiments in field settings with more than triple the sample sizes (128 and 177) and double-blind procedures, but found near-zero effects (r = −.03 and .02). In both cases, Bayesian analyses suggest there is substantially more evidence for the null hypothesis of no effect than for the original physical warmth priming hypothesis.

没有证据表明，经历身体温暖会促进人际交往的温暖

Williams and Bargh（2008）报告说，拿着一杯热咖啡会使参与者判断一个人的性格较温暖，而拿着治疗性加热垫会使参与者选择为他人而不是为自己奖励。这些实验具有较大的效果（r = .28和.31），较小的样本量（41和53名参与者），并且几乎没有统计学上的显着结果。我们尝试在野外设置中使用大于两倍的样本量（128和177）和双盲程序来重复这两个实验，但发现效果几乎为零（r = −.03和.02）。在这两种情况下，贝叶斯分析都表明，没有任何效果的无效假设的证据要多于原始的物理温暖启动假设的证据。
