Chapter 12 & Chapter 13 & Conclusion
Summary
In chapter twelve, Hallinan talks about affordances and how this concept can help avoid human errors. One of the main reasons why we cannot prevent making errors is because we blame the incorrect reason.
In chapter thirteen, he describes how people believe in the "grass looking greener". This can be attributed to us focusing on the very obvious cues and leaving the other ones ignored. One example he gives is the idea of the positive social life people have about California, but in reality many people move out after only a few years of living there. In the conclusion chapter, he summarizes all of the previous chapters and the mistakes he talked about and gives some advice on how to preventing these mistakes.
Discussion
I liked reading the conclusion chapter because he gives you an insight on how you can prevent mistakes and that is what he tries to emphasize on all his previous chapters. I like to hope for the best of my actions and if something happens along the way I want to learn from that experience to make a better decision in the future.

Book Reading # 49
Chapter 10 & Chapter 11
Summary
In chapter ten, Hallinan describes how people tend to feel overconfident and feel they are extremely good at something when in reality they may not be even that great. This overconfidence can lead to mistakes. A good practice to avoid mistakes by being overconfident is trying to ask for feedback.
In chapter eleven, he talks about how people try to do things the easy way instead of following detailed instructions in manuals. People -like the title suggests- rather wing a situation instead of practicing for it.
Discussion
Chapter eleven is interesting to read because it can help us to prepare better for our class presentations. Our awesome TAs made sure we were aware that we should not wing project presentations, and it was definitely beneficial. It was also funny because we say that people in Mexico avoid reading manuals, that we rather waste time trying to make things work by playing with them instead of reading the instructions and saving some time.

Chapter 6: We’re in the Wrong Frame of Mind & Chapter 7: We Skim
Summary
Chapter six focuses on discussing frames and anchors. It also talks about how people strongly bias their decisions based on the way something is framed. Chapter seven talks about how people get used to skimming information. This can cause the person not to fully focus on the information. Once the main idea has been understood, people do not feel the urge to read sentence by sentence anymore. Hallinan also highlights the importance of context.
Discussion
Chapter seven is funny because that is exactly what a lot of people do when reading information. People skim the information and rely on context being present to extract the most of the information.

Chapter 8 & Chapter 9
Summary
In chapter eight, Hallinan discusses how humans tend to manipulate memory details so that it is simpler to rationalize or understand them. Hallinan points out that studies has shown that people tend to straighten lines on a map such as the drawing of the Seine river. Also since people do not recall exact details about their memories, they tend to change their stories a little. In chapter nine, Hallinan compares how men and women perceive things differently. He talks about how men tend to be more confident then women, and therefore they are more likely to take risks.
Discussion
The point about people tending to skew stories because humans do not recall exact details has already been a topic of discussion in this class. As far as the point of making things easier to understand, I totally agree with his point of view. The latter chapter made me think about all of the discussions I have had with my girl friends. But it had never made me think how this could affect the CHI world, it could be interesting to see if there should be gender oriented or what can we do to narrow this difference.

Chapter 4: We Wear Rose Colored Glasses & Chapter 5: We Can Walk and Chew Gum - but Not Much Else
Summary
In chapter four, Hallinan discusses how humans tend to see and remember things in a way that makes us look better. In some sense we look through rose colored glasses to cover up some of our mistakes. In the next chapter, Hallinan discusses that humans are not good are multitasking and how this can lead to errors. He claims that we can only focus on one event at a time.
Discussion
I enjoy the fact that Hallinan describes his chapters with long descriptions and examples. The title of chapter five is funny, and I do not completely agree with his claim that humans cannot multitasking. My roommate is always telling me to not talk to him when he is doing something else because he can only focus on one event at a time. On the other hand, there are many examples of how people are talking on the phone, writing down notes, and walking perhaps. When it really matters is when we need to pay undivided attention to a certain event.

Chapter 2: We All Search for Meaning & Chapter 3: We Connect the Dots
Summary
Chapter two talks about memory and how people are prone to remembering things when they have some sort of personal meaning as supposed to meaningless things. Hallinan gives as an example people forgetting names. In the next chapter, Hallinan talks about people making choices based on what he calls "invisible" factors. Also as the chapter title suggests, Hallinan describes how the human brain connects meaning without you realizing it.
Discussion
The example Hallinan gives in chapter two about forgetting names is something that happens to me all of the time. There are people that I take classes with, and I recognize their faces but tend to forget their names unless we worked on a project together. Chapter three reminds me on how important a first impression is.

Book Reading # 39 - Why We Make Mistakes
Chapter 0: Introduction & Chapter 1: We Look but Don't Always See
Summary
Chapter zero introduces the concept that people frequently make mistakes and gives some examples such as the car example. The author Hallinan points out that if people are aware they make mistakes, they should decrease the amount of mistakes in the future. In the following chapter he claims how things that cause mistakes are sometimes right in front of us and yet we do not see them.
Discussion
This idea that the chapter one describes where we look but don't always see is really interesting because we would like to think that we never do this when in fact we do this all the time. We sometimes focus on a certain aspect of an environment that we forget other important details. I think this is the main idea behind people proofreading a paper before final submission, checks and balances in government, etc. This is particularly important to keep in mind when implementing software.
