The relationship between personality traits and biased assimilation, evaluating arguments, and persuasive messages more favorably if supporting pre‐existing attitudes, lacks adequate research. Research suggests that higher narcissistic traits are associated with biased reactions. Additionally, research suggests that people with greater scientific reasoning abilities have more biased reactions to information that challenges their attitude, as they more easily locate flaws on topics that oppose their beliefs. Participants (N = 260) completed measures to identify their views on trans bathroom use, as well as other personality and attitude measures. They were randomly assigned to read one of the two articles using fake scientific data that either supported trans people using a bathroom reflecting their gender identity or that they should use a bathroom matching their sex‐assigned at birth. Participants rated the quality of the article significantly higher when their opinion on bathroom use was congruent with the article than when it was incongruent. We used regression analyses with participants' perceptions of the quality of the article as the outcome variable and scientific reasoning scores, narcissism personality index scores, open‐mindedness scores as predictor variables. In the mismatch group, the higher the scores on scientific reasoning, the lower the ratings of the quality of the opinion incongruent article. In the match group, the higher the scores on open‐mindedness, the lower the ratings of the quality of the opinion congruent article. This research suggests that bias reduction is necessary to function in a world where scientific facts are called into question on a consistent basis.

偏见及其对跨性别浴室使用意见的影响

缺乏足够的研究，如果支持先前存在的态度，人格特质与偏见的同化，评估论点和有说服力的信息之间的关系更有利。研究表明，较高的自恋特征与偏见有关。此外，研究表明，具有较强科学推理能力的人对挑战其态度的信息的反应更加偏颇，因为他们更容易在与自己的信念背道而驰的问题上找到缺陷。参加人数 = 260）已完成的措施，以确定他们对跨浴室使用的看法，以及其他人格和态度措施。他们被随机分配使用虚假的科学数据阅读这两篇文章之一，这些科学数据要么支持跨性别者使用反映其性别身份的洗手间，要么应使用与他们出生时所分配的性别相匹配的洗手间。当参与者对浴室使用的看法与该文章一致时，与该文章不一致时，与会人员认为该文章的质量明显更高。我们使用回归分析，将参与者对文章质量的看法作为结果变量，并将科学推理分数，自恋人格指数，开放思想分数作为预测变量。在不匹配组中，科学推理的得分越高，意见不一致的文章的质量等级越低。在匹配组中，思想开放的得分越高，意见一致的文章的质量得分就越低。这项研究表明，减少偏见对于在一个始终如一地质疑科学事实的世界中发挥作用是必要的。
