While William of Ockham is often credited with the formulation of this mental model, it’s an ancient one. Aristotle wrote: “Other thin...
Occam’s razor is pretty easy to understand. It says that other things being equal, simpler explanations are generally better than more complex ones. It is used everyday by scientists to choose between competing theories. The problems? First, there is actually no empirical evidencethat the world is simple, and therefore simpler solutions are more li...

When making a decision, a lot is going on inside our brains: many parts of the cortex get involved, emotional regulation comes into play, and the fight-or-...
