The market is not perfectly efficient. Small cap stocks outperform large cap stocks; the S&P500 outperforms leaving money under your mattress. I am more than willing to bet that if you combine these methods with an algorithm that estima

I'm not a doctor, but I once did a college report on Optical Coherence Tomography a long time ago. The body scatters light. Just like the body scatters sound. Maybe sometime in the future we will have precision devices that can access

That's a good question, and worth pondering outside the context of the state's monopoly on violence. Would the average person prefer Ted Bundy kill them immediately or lock them in his basement for 20 years? This entire comment ch

I believe Duskstar's point was that minorities without records would be treated better, and non-minorities with records would be treated worse. Thus, police would react to someone's criminal history, and not just their skin color.
