What is Why We Make Mistakes about?
Why We Make Mistakes is about the kinds of mistakes we commonly make, and the reasons behind them. With a broad focus encompassing neuroscience, psychology and economics, the book provides convincing explanations for our often fallible perception, our inability to recall simple data and the many biases that direct our decision making without us being aware.

Our view of the world is limited by our eyes and our minds.
Before he became famous, Burt Reynolds entered a bar and noticed a broad-shouldered man harassing the patrons. Reynolds told the man to stop, but to no avail. Eventually Reynolds punched him, sending him flying through the air.
That’s when Reynolds noticed that the man had no legs. How could he have not seen that?
The world is incredibly complex: we’re constantly confronted with much more information than our brains can handle; plus, there are many different ways to look at every situation.
Part of the problem is that our field of vision is literally limited to 180 degrees, so at any given moment we see only half of what there is to see.
But there’s also a psychological aspect to the problem: a scene will appear differently to one person than it will to another.
For instance, when we observe an event, sometimes what we notice is determined by the person we identify with. When watching a male thief steal a woman’s purse, for example, men tend to focus on the thief while, in general, women focus on the female victim.
Another way our view of the world is limited is our tendency to see only what we expect to see where we expect to see it. Which means we often fail to notice many, sometimes key, details.
Even seasoned professionals are susceptible to this phenomenon. The “miss” rates are extremely high in professions that require people to look out for certain unusual objects – like tumors or bombs.
For example, the number of flight passengers who attempt to smuggle firearms through security is only one in a million. As a result, baggage screeners simply don’t expect to find guns in passengers’ luggage and their screening process becomes lax, causing them to miss a quarter of all firearms.
And that’s how it was possible for Burt Reynolds to miss the fact that the broad-shouldered bully had no legs: he simply couldn’t see what was right in front of his eyes.

Great app. Good selection of book summaries you can read or listen to while commuting. Instead of scrolling through your social media news feed, this is a much better way to spend your spare time in my opinion.
