这篇论文使用了一个简单的类比。枪的设计是用来射击子弹的，但很明显，如果可能的话，意外射击是一个应该避免的危险。因此，枪支有安全锁，旨在保护使用者和旁观者。交互式计算机系统有时也会意外地做坏事，但像“安全锁”这样的东西经常没有得到足够的实施，以帮助保护用户或旁观者免受伤害。更糟糕的是，用户界面经常在输入错误时表现得非常不可预测--而不是阻止错误并要求用户更正错误。这有点像行为不端的枪支。计算机和嵌入日常设备中的计算机并不总是像枪支那样危险，尽管在许多情况下它们也可能一样危险。医疗设备可能会给患者带来未被发现的过量用药。像收音机这样的车内娱乐设备，通过其设计糟糕的用户界面，可能会导致司机发生事故。电子表格中的一个失误可能是一个组织走向破产的第一步。诸若此类。解决方案应该包括更好的设计，包括安全锁的概念，以阻止某些形式的用户错误。
This paper uses a simple analogy. A gun is designed to shoot bullets, but it is obvious that accidentally shooting is a danger one should avoid if at all possible. Thus guns have safety locks, which aim to protect users and bystanders. Interactive computer systems sometimes accidentally do bad things too, but something like "safety locks" are not often enough implemented to help protect user or bystanders from harm. Worse, user interfaces often behave quite unpredictably with erroneous input - rather than blocking errors and requiring the user to correct them. This is a bit like guns that misbehave. Computers and computers embedded in everyday devices are not always as dangerous as guns, although there are many cases where they can be as dangerous. Medical devices may give patients undetected overdoses. In-car entertainment devices, like radios, may, through their badly-designed user interfaces, cause a driver to have an accident. A slip in a spreadsheet may be the first step towards an organisation going bankrupt. And so on. The solution should include better design, including the concept of safety locks, that block some forms of user error.
