12.The following appeared in a memo from a vice president of Alta Manufacturing.

"During the past year, Alta Manufacturing had thirty percent more on-the-job accidents than nearby Panoply Industries, where the work shifts are one hour shorter than ours. Experts believe that a significant contributing factor in many on-the-job accidents is fatigue and sleep deprivation among workers. Therefore, to reduce the number of on-the-job accidents at Alta and thereby increase productivity, we should shorten each of our three work shifts by one hour so that our employees will get adequate amounts of sleep."

1.错误类比，相对于AM来说，PI具有更少的事故。但是这两个属于不同的企业环境文化等，不具有可比性。

2.作者错误的假设了AM的事故发生率高是由于比PI多一个小时的时间造成的，也可能是其他的原因，诸如工作环境等等。

3.因果错误，即便是引文多一个小时造成的，作者假设如果缩短一个小时的工作时间，那么员工就能获得更多的睡眠，这显然是无法保证的。员工可能并不会用这一个小时来睡觉。因此就更不用说通过充足的睡眠来降低事故的发生率了。

4.作者只是简单的比较了一下这两个公司的事故发生率，这只是一个相对的概念，不具有说服力。应该再提供一个绝对的数值来进行比较。
