Key insights

• ⚡ Human brain tripled in size due to the development of the prefrontal cortex. Prefrontal cortex acts as an experience simulator.
• 🧠 Impact bias causes people to overestimate the impact of different outcomes on their happiness.
• 📊 Recent study shows major life traumas have no impact on happiness after three months. Happiness can be synthesized by a psychological immune system.
• 😊 Examples of people synthesizing happiness: Jim Wright, Maurice Victim, Harry Langerman.
• 🎭 Synthetic happiness is the happiness we create when our choices are constrained or altered. Experimental data from the free choice paradigm supports the concept of synthetic happiness.
• 🔀 People can synthesize happiness even when they don't realize they own something. Our psychological immune system allows us to change our affective reactions and choose among different futures.
• 📸 Experiment at Harvard on photography choices and their impact on happiness.
• 🌟 Preferences can lead to dissatisfaction by overrating differences between outcomes. Synthetic happiness can be synthesized even when we don't get what we originally wanted.

Q&A

• What leads to dissatisfaction and how can synthetic happiness be achieved?

  Our preferences can lead us to overrate differences between outcomes, causing dissatisfaction. However, synthetic happiness can be synthesized even when we don't get what we originally wanted.

• How does the ability to choose and change one's mind impact happiness?

  People's ability to choose and change their minds can affect their happiness, as demonstrated by an experiment at Harvard on photography choices and their impact on happiness.

• How does the psychological immune system contribute to synthesizing happiness?

  The psychological immune system allows people to synthesize happiness, change affective reactions, and choose among different futures, even when they don't realize they own something. It can also be synthesized after major life traumas.

• Is synthetic happiness as enduring as natural happiness?

  Yes, synthetic happiness is as real and enduring as natural happiness, supported by experimental data from the free choice paradigm.
