Daniel Kahneman's 2011 book "Thinking Fast and Slow" describes two ways that we make decisions.
Fast Thinking (sometimes called "System 1") is intuitive. We often do not know on what unconscious knowledge we base our decisions. This system can be helpful when we have limited information and limited time to act.
Slow Thinking (sometimes called "System 2") uses logic and known facts to make decisions. This system can lead to more accurate and appropriate responses.
System 2 tends to be more reliable because we try to take into account all available information, but System 1 can also be useful because our unconscious mind provides a lot of context, and it allows us to react more quickly.
Kahneman provides numerous examples throughout the book. Many are obvious (poor people value a gain of $100 far more than rich people; People often respond differently depending on the phrasing of a question or scenario) but some are thought-provoking (people are more willing to take risks if they ) but others are less obvious (e.g., A Credit Card Surcharge and a Cash Discount are the same, but most people find the latter more appealing.)
The most interesting examples are those in which people behave in a seemingly illogical manner. For example, when people hear a description of a woman, they may assume she is more likely to be a feminist librarian than a librarian. This logic is absurd because all feminist librarians are also librarians so the second category will be at least as broad as the first.
"Thinking Fast and Slow" provides an interesting list of ideas and psychological experiments. It includes enough applicable content here to make it worthwhile.
