Book Reading 50 – Why We Make Mistakes

Chapter 12 – We Don’t Constrain Ourselves
Summary

The importance of constraints was discussed in this chapter.  Constraints drastically deplete the probability for error by removing sources for common errors.  Many don’t learn from their mistakes, because they did not properly find the source of it.  Hallinan also adds how removing complexity and adding constraints can greatly improve designs.

Discussion
This chapter reminded me a little of The Design of Everyday Things.  This was a broader discussion though.  The discussion about medical errors was kind of startling.  I know it was there to make his point clear, but hearing things like that can make you worry about having any surgery done.


Chapter 13 – The Grass Does Look Greener
Summary

People tend to have inaccurate views on things when they don’t have the full picture.  Hallinan quotes someone as saying, “we tend to zero in on things that are easily observed and give too much attention to those.”  This tends to be the main source for misjudgments.  Learning to concentrate more on the big picture by taking in as many details as possible can solve this.

Discussion
It was interesting hear about the pole regarding living locations.  California does seem like a great place to live when you concentrate on the weather.  However, there is a lot of congestion there and finding the right place to live is extremely important.  I’m honestly just fine living in the northeast somewhere.


Conclusion
Summary

A major point Hallinan makes is to think small.  It is the tiniest things that can make the largest impact on a person’s behavior.  He also added that attitude has a large effect on many things, like how we view life.  While this may be simple, he explains that many people forget this.  The last message he gives is how our living location is not what makes us happy, but how we use our time.

Discussion
The last part about how we use our time seems like a huge concept to me.  It’s not complicated, but it’s just so important.  A lame bar is only a lame bar if you decide to do nothing about it.  For me, the people you are with define the level of enjoyment about a place.  So just as Hallinan explained, it is definitely not the location you are in.  It’s the way you decide to spend your time that matters the most and defines your life.
