Take the circumstances in your life seriously, but not literally. Here's why.
- Galileo was quite controversial, in part, because he argued that Earth moved around the sun, despite people's senses deluding them that the world was static.
- Evolution may have primed us to see the world in terms of payoffs rather than absolute reality — this has actually helped us survive. Those who win payoffs are more likely to pass on their genes, which encode these strategies to get to the "next level" of life.
- It's important to listen to people's objections because they may bring something to your attention outside your ken. Learn from them to make your ideas sharper.
When it comes to scientific theory, (or your personal life) be sure to question everything.
- The theories we build to navigate the world, both scientifically and in our personal lives, all contain assumptions. They're a critical part of scientific theory.
- Cognitive psychologist Donald Hoffman urges us to always question those assumptions. In this way, by challenging ourselves, we come to a deeper understanding of the task at hand.
- Historically, humans have come to some of our greatest discoveries by simply questioning assumed information.
Exploring the idea that objects we perceive in everyday life do not reflect objective reality.
- Professor of cognitive science Donald Hoffman presents his theory that the world we perceive is a virtual reality. Hoffman has tested this theory by running successful computer simulations that suggest there is no objective reality.
- When it comes to Nick Bostrom's simulation theory, Hoffman agrees with parts and disagrees with others. Hoffman argues that, while space time and physical objects do not correspond with objective reality, conscious experiences like the smell of garlic and the feel of velvet cannot be produced by the simulation.
- "You can't start with unconscious ingredients and boot up consciousness," Hoffman says.
