我们认为的“常识”其实常常是并不正确或者带有误导性或者是过时的信息。
比如很久之前人们认为太阳绕着地球转，但后来发现并不是这样的。比如我们曾经龙卷风来临的时候应该躲到高架桥的下面，但后来发现这样做非常危险，应该尽一切可能避免。又比如很多人认为失踪案件应该等24-48小时才报警，但实际上失踪案件应该立即报警，因为案件发生的前几天是找回失踪人员的绝对关键时期。
我们应当在需要的时候查验和搜索我们以前知道的“信息”，这绝对是一个很好的做法。想一想吧，就在这十几年间，有多达三分之一的中亚国家变更了名字和边境线，甚至冥王星也不再被认为是一颗行星。信息有变化，知识有更新，都是非常正常的事情。 source
