对p值的常见误解是基于对结果重要性的某些信念和归因。因此，它们影响到专业人员的决定，危及干预措施的质量和有效科学知识的积累。我们对164名学术心理学家（134名意大利人，30名智利人）进行了一项关于这个主题的调查。我们的研究结果与以前的研究一致，并表明一些参与者不知道如何正确解释p值。逆概率谬误提出了最大的理解问题，其次是复制谬误。这些结果凸显了研究人员统计再教育的重要性。提出了提高统计认知的建议。
Common misconceptions of p-values are based on certain beliefs and attributions about the significance of the results. Thus, they affect the professionals' decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italian, 30 Chilean) questioned on this topic. Our findings are consistent with previous research and suggest that some participants do not know how to correctly interpret p-values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy. These results highlight the importance of the statistical re-education of researchers. Recommendations for improving statistical cognition are proposed.
