评“粒子物理实验结果的再现与复制”

Comment on "Reproducibility and Replication of Experimental Particle Physics Results"

Andrew Fowlie

摘要:

我想感谢Junk和Lyons(arXiv:2009.06864)开始讨论高能物理(HEP)中的复制。Junk和Lyons最终认为,HEP从过去的失败中吸取了教训,其他领域可以从我们的程序中学习。他们强调,如果在寻找新物理学的过程中犯了第一类错误,实验合作将冒着失去遗产的风险,并概述了为避免这种错误而采取的警惕措施,例如数据盲法和严格的$5σ$阈值。然而,这场讨论忽略了房间里的大象:在寻找新物理学的过程中,经常会出现异常现象,导致大量的科学活动,但不会用更多的数据来复制。

英文摘要:

I would like to thank Junk and Lyons (arXiv:2009.06864) for beginning a discussion about replication in high-energy physics (HEP). Junk and Lyons ultimately argue that HEP learned its lessons the hard way through past failures and that other fields could learn from our procedures. They emphasize that experimental collaborations would risk their legacies were they to make a type-1 error in a search for new physics and outline the vigilance taken to avoid one, such as data blinding and a strict $5σ$ threshold. The discussion, however, ignores an elephant in the room: there are regularly anomalies in searches for new physics that result in substantial scientific activity but don't replicate with more data.
