A set of simple thinking tools that can improve your sense of how the world works
People do not upgrade their knowledge. The level of education doesn't seem to matter; in fact, it looks as though the higher the level of education, the poorer the results. People have a worldview that dates to when their teachers left school.
Overdramatic worldview is another problem. Even when people have the latest information, they tend to get the facts wrong because their worldview tends to blow things out of proportion. This tendency makes people provide negative answers to factual questions.
Changing an overdramatic worldview is problematic because it is connected to how our brains work. We jump to conclusions very quickly, and we also have a craving for drama, making us interested in gossip and dramatic stories.
If you are more interested in being right than thinking critically, this is not a book for you. However, if you are willing to change your worldview and replace your instinctive reaction with a more critical and factual response to the world, please you’ve chosen the right summary.
