Wixted, Mickes, and Fisher (this issue) take issue with the common trope that eyewitness memory is inherently unreliable. They draw on a large body of mock-crime research and a small number of field studies, which indicate that high-confidence eyewitness reports are usually accurate, at least when memory is uncontaminated and suitable interviewing procedures are used. We agree with the thrust of Wixted et al.'s argument and welcome their invitation to confront the mass underselling of eyewitnesses' potential reliability. Nevertheless, we argue that there is a comparable risk of overselling eyewitnesses' reliability. Wixted et al.'s reasoning implies that near-pristine conditions or uncontaminated memories are normative, but there are at least two good reasons to doubt this. First, psychological science does not yet offer a good understanding of how often and when eyewitness interviews might deviate from best practice in ways that compromise the accuracy of witnesses' reports. Second, witnesses may frequently be exposed to preinterview influences that could corrupt reports obtained in best-practice interviews.
威克斯泰德、米克斯和费舍尔(本期问题)对一种常见的观点提出异议,即目击者的记忆本质上是不可靠的。他们借鉴了大量模拟犯罪研究和少数现场研究的成果,这些研究表明,高可信度的目击者报告通常是准确的,至少在记忆没有受到污染且采用了适当的访谈程序的情况下是如此。我们同意威克斯泰德等人观点的主旨,并欢迎他们邀请我们共同面对对目击者潜在可靠性的严重低估。然而,我们认为,对目击者可靠性的高估也存在类似的风险。威克斯泰德等人的推理意味着近乎原始的条件或未受污染的记忆是规范的,但至少有两个充分的理由对此表示怀疑。首先,心理学科学尚未很好地理解在何种情况下以及在何种频率下,目击者访谈可能会偏离最佳实践,从而影响目击者报告的准确性。其次,目击者可能经常受到访谈前影响的干扰,这些影响可能会破坏在最佳实践访谈中获得的报告。
