Active Funds vs. Index Funds: Performance, Bias, and Evidence

The people paid to pick winning stocks mostly lose to a fund that simply buys everything, and it looks worse once dead funds are counted properly.

Consciousness and the Hard Problem: Neuroscience, Buddhism, and Skepticism

Why a brain produces felt experience remains the hardest open question about the mind.

Overdiagnosed: How Profit Reshaped ADHD Care

Overdiagnosed: How Profit Reshaped ADHD Care

Rising ADHD diagnoses track less with patient need than with an industry that profits from every prescription.

The frameworks assign ownership differently, from role charts that clarify who recommends and who approves to pre-mortems that stress-test a call before it is made, and they openly trade inclusion against speed. Matching one to your team turns arguments about who decides into decisions that actually hold.
