Summary
Donald Norman starts this chapter by stating the differences between human errors and machine errors; stating that human errors are easy to recover from whereas machine errors are not. There are basically two types of errors: mistakes and slips. Slip errors can be placed in six categories: capture, description, data-driven, associative activation, loss-of-activation, and mode.
While describing the process used by humans in terms of thought (or at least theories of it), Norman describes everyday structures in two categories. Shallow structures come from many choices, but each one of them is simple, whereas narrow structures arise from a small number of possibilities. At the end, the author opts for adopting a philosophy that takes errors into account when designing everyday things

Discussion
I thought the chapter was interesting since it discusses how errors need to be taken into account when designing everyday things. As I am reading the book, I realized that there lots of things that need to be considered in order to design objects that are safe and easy to use.
