Why We Make Mistakes
Joseph T. Hallinan
2009 Broadway
Chapter 0
Summary:
People make mistakes all the time, and there isn't much we can do about it. We make mistakes based on our biases, the way we perceive the world, and our own lack of awareness. There are ways to avoid making mistakes, but they require more insight into what we do.
Discussion:
This is mostly stuff that's been covered in previous readings, though there are more numerical values than some of the material we've seen (e.g. the % of people who had forgotten passwords after three months). It is, however, nice to know that aenesthesiologists are much better than they were when I was but a lad.

Chapter 1
Summary:
This chapter examines visual mistakes. We only really see around 2% of our field of vision clearly, and the rest is peripheral. Men tend to notice different things than women, and lefties are more likely to remember different object orientations than right-handed people. We all tend to think that we see everything it great detail, but fail to notice glaring changes in people and scenery right under our noses. Finally, if we continuallty fail to spot something in a scene, we are more likely to miss it when it is indeed present.

Discussion:
This chapter should be unsurprising to anyone who has seen the "dancing bear" or "color changing scenery" videos online, where viewers often miss outlandish events occuring on camera because they've been told to focus somewhere else. I suspect this is where most of the "they came out of nowhere" car accidents stem from. I must admit that I found the section detailing how we are "programmed to fail" particularly disturbing. I certainly don't want medical screeners missing vital information on a scan or x-ray.
