Useful Delusions

Some false beliefs help us
Vedantam and Mesler argue that self-deception is not always harmful. Some beliefs that are not strictly true can help people cope, connect with others and find meaning in life. The book explores both sides.
- IDEA 2
Placebos show belief's power
The authors describe how placebos, treatments with no active ingredient, can make people feel better. Expectations alone can change how people experience pain and illness. Doctors have long noticed this effect.
- IDEA 3
Hope keeps people going
The authors explain that optimism, even when unrealistic, can help people persevere. Believing things will improve can motivate effort that makes improvement more likely. Optimists often try harder and longer.
