英国伦敦大学学院Aswin Chari团队研究了从“这不是火箭科学”和“这不是脑手术”到“这是在公园里散步”的未来比较研究。相关论文于2021年12月13日发表在《英国医学杂志》上。
为了比较神经外科医生和航空航天工程师的认知测试分数，以帮助解决一个古老的争论：“这不是脑手术”或“这不是火箭科学”哪个短语最有智慧，研究组在英国、欧洲、美国和加拿大进行了一项国际前瞻性比较研究。
共招募到748人（600名航空航天工程师和148名神经外科医生）。数据整理后，最终分析包括401个完整的数据集（329名航空航天工程师和72名神经外科医生）。主要观察指标为验证在线测试（Cognitron的英国智力测试），测量认知的不同方面，包括计划和推理、工作记忆、注意力和情绪处理能力。
神经外科医生在语义问题解决方面的得分明显高于航空航天工程师。航空航天工程师在心理操纵和注意力方面的得分明显高于神经外科医生。两组之间的记忆力、空间问题解决、解决问题速度和记忆唤起速度得分没有显著差异。当将各组在六个领域的得分与普通人群的得分进行比较时，只有两个差异是显著的：神经外科医生的问题解决速度更快，但记忆唤起速度较慢。
研究结果表明，在不需要快速解决问题时，使用短语“这不是脑手术”可能更为正确。神经外科医生和航空航天工程师可能都被不必要地捧在台上，“这是在公园里散步”或其他与职业无关的短语可能更合适。其他专业或也应该被捧上台面，未来的工作应该着眼于确定最值得从事的职业。

Abstract:
Objective To compare cognitive testing scores in neurosurgeons and aerospace engineers to help settle the age old argument of which phrase—“It’s not brain surgery” or “It’s not rocket science”—is most deserved.
Design International prospective comparative study.
Setting United Kingdom, Europe, the United States, and Canada.
Participants 748 people (600 aerospace engineers and 148 neurosurgeons). After data cleaning, 401 complete datasets were included in the final analysis (329 aerospace engineers and 72 neurosurgeons).
Main outcome measures Validated online test (Cognitron’s Great British Intelligence Test) measuring distinct aspects of cognition, spanning planning and reasoning, working memory, attention, and emotion processing abilities.
Results The neurosurgeons showed significantly higher scores than the aerospace engineers in semantic problem solving (difference 0.33, 95% confidence interval 0.13 to 0.52). Aerospace engineers showed significantly higher scores in mental manipulation and attention (0.29, 0.48 to 0.09). No difference was found between groups in domain scores for memory (0.18, 0.40 to 0.03), spatial problem solving (0.19, 0.39 to 0.01), problem solving speed (0.03, 0.20 to 0.25), and memory recall speed (0.12, 0.10 to 0.35). When each group’s scores for the six domains were compared with those in the general population, only two differences were significant: the neurosurgeons’ problem solving speed was quicker (mean z score 0.24, 95% confidence interval 0.07 to 0.41) and their memory recall speed was slower (0.19, 0.34 to 0.04).
Conclusions In situations that do not require rapid problem solving, it might be more correct to use the phrase “It’s not brain surgery.” It is possible that both neurosurgeons and aerospace engineers are unnecessarily placed on a pedestal and that “It’s a walk in the park” or another phrase unrelated to careers might be more appropriate. Other specialties might deserve to be on that pedestal, and future work should aim to determine the most deserving profession.
