The Wealth Asymmetry: The pain of losing $100 is not equal and opposite to the pleasure of winning $200. In the neural accounting that quietly drives your investment behaviour, your job choices, and your willingness to start over, losses are weighted roughly twice as heavily as gains. This single asymmetry is the most expensive cognitive … Read more
The Quitting Premium: The most profitable decision you will make in any decade is almost always one you have already postponed for years. The cognitive trap that keeps you in the wrong job, the bad investment, the failing project, and the unrewarding relationship has a name: the sunk cost fallacy. It is one of the … Read more

In a 1977 American replication of the same question, the figure was 88 percent. The mathematical impossibility is obvious — by definition, only 50 percent of drivers can actually be above the median — yet … Read more
