Cognitive psychologist Donald Hoffman hypothesizes we evolved to experience a collective delusion — not objective reality.
- Donald Hoffman theorizes experiencing reality is disadvantageous to evolutionary fitness.
- His hypothesis calls for ditching the objectivity of matter and space-time and replacing them with a mathematical theory of consciousness.
- If correct, it could help us progress such intractable questions as the mind-body problem and the conflict between general relativity and quantum mechanics.
If ever there was a food that holds a lesson for building bridges in a fractured America, it's the cabbage roll.
- Dr. Kurt Gray of University of North Carolina at Chapel Hill unpacks a psychological and political phenomenon: reactive devaluation.
- This negative phenomenon is driving polarization in the U.S.. The good news? It has an equally powerful counterpart: benevolence.

We don't perceive time in an objective fashion; instead, the brain interprets time in a complex and amorphous way.

- These four temporal illusions demonstrate the subjective nature of time and the influence the subconscious has over our lived experience.
A new study found that smoking cannabis at a young age is associated with reduced brain volume in a region responsible for processing emotions on people's faces.
- The study involved using MRIs and emotional processing tasks to compare 20 regular cannabis users to 35 non-users.
- The results showed cannabis users had lower brain volumes in a region called the left rostral anterior cingulate cortex (rACC).
- Still, the researchers noted that their study didn't establish causality.
