自信的证人被认为比不自信的证人更可信，准确的证人被认为比不准确的证人更可信。但这些影响是独立的吗？两个实验表明，对错误证词有信心的证人比对错误证词没有信心的证人更容易受到证词错误的损害。此外，在犯错之后，不自信的证人可能比更自信的证人显得更可信。我们对这些结果的解释是，人们在评估证词和其他社会交流时，会对源校准进行推断。
Confident witnesses are deemed more credible than unconfident ones, and accurate witnesses are deemed more credible than inaccurate ones. But are those effects independent? Two experiments show that errors in testimony damage the overall credibility of witnesses who were confident about the erroneous testimony more than that of witnesses who were not confident about it. Furthermore, after making an error, less confident witnesses may appear more credible than more confident ones. Our interpretation of these results is that people make inferences about source calibration when evaluating testimony and other social communication.
