Book Reading 39 – Why We Make Mistakes

Chapter 0 – Introduction
Summary

Hallinan gave a brief outline for what he wants to accomplish with his book.  He went over various kinds of mistakes and the reasoning behind them.  Many mistakes are made simply because of how humans are and how the mind operates, but he says there are certain way people can act in order to decrease mistake tendency and help to overcome it.

While this almost seems to have a similar vibe to Norman’s books, I am pretty excited to see what Hallinan has to say.  The perspective is interesting in looking at the reasons behind mistakes.  I enjoyed learning the reasons behind a design is terrible, so it should be just as intriguing to learn about why mistakes happen.


Chapter 1 – We Look but Don’t Always See
Summary

The reasons behind why people miss certain key details was discussed.  Sometimes this can be from inexperience with the subject of the details like with skills in golf.  Another instance is the frequency of something occurring.  If an object appears more often, then people have a higher chance of realizing when it is and isn’t there.

Discussion
This chapter gave a lot of insight into why visual mistakes are made.  The frequency of an object affecting how often it is noticed was particularly interesting to me.  Most of the things he spoke about I had not thought about before, so hearing about them was beneficial.
