This article examines the violation of longstanding scientific norms, in particular universalism, objectivity, and truth orientation by new identity policies such as the principle of ‘diversity, equity, and inclusion’ (DEI). The imposition of this principle by public opinion, administration, and mass media, particularly in the United States but also in other countries, contradicts the principle of equal opportunity regardless of race, gender, nationality, and class, by putting the emphasis of assessment on group identities. The implementation of this principle has begun to damage careers, threaten scientists and lower standards in academia. In order to provide a historical perspective, I review how the violation of scientific norms has impacted scientific success in past authoritarian countries, in particular the USSR under Stalin, and Nazi Germany. The comparison with past authoritarian countries does not aim at equating situations from then and now, but can help understand social and political mechanisms of current events. It also highlights in a drastic way consequences that a violation of scientific norms may have for science today.

本文探讨了新的身份政策（例如“多样性、公平和包容”（DEI）原则）对长期科学规范的违反，特别是普遍主义、客观性和真理导向。舆论、行政部门和大众媒体强加这一原则，特别是在美国，但在其他国家也是如此，因为强调评估，与不分种族、性别、国籍和阶级的机会均等原则相矛盾。群体身份。这一原则的实施已经开始损害职业生涯、威胁科学家并降低学术界的标准。为了提供历史视角，我回顾了违反科学规范如何影响过去专制国家的科学成功，特别是斯大林领导下的苏联和纳粹德国。与过去威权国家的比较并不是为了将当时和现在的情况等同起来，而是可以帮助理解当前事件的社会和政治机制。它还以剧烈的方式强调了违反科学规范可能对当今科学产生的严重后果。
