Some people are open books, with their distinctive personalities being accurately perceived after a brief interaction, whereas others are harder to read. Such open books have in turn been found to have greater well-being, at least within lower-stakes, platonic getting-acquainted interactions. Do individual differences in expressive accuracy emerge in higher-stakes settings, such as first dates, and are people higher in well-being still easier to read? Using a speed-dating paradigm (N = 372; N_dyads = 4723), accuracy on average was significant but relatively low. Nevertheless, strong individual differences in expressive accuracy emerged and were associated with well-being. In sum, although it may be more difficult to form accurate impressions on first dates, targets higher in well-being may make the task easier.

有些人是公开的书，经过短暂的互动即可准确地识别其独特个性，而其他人则更难阅读。反过来说，至少在低赌注，柏拉图式的相识互动中，这类开放书籍的幸福感更大。在较高的场合（例如初次约会）中，表达准确性的个体差异是否会出现？人们的幸福感是否还会更容易阅读？使用速度约会范例（N  = 372; N _dyads = 4723），平均准确度很高，但相对较低。然而，在表达准确性上出现了强烈的个体差异，并与幸福感相关。总而言之，尽管在初次约会时可能难以形成准确的印象，但是将目标定为较高的幸福感可能会使这项工作变得容易。
