A strange thing happens when a crowd tries to leave through the same narrow doorway. The first few people move quickly. Then the flow slows. People push harder. That can make everyone move even slower. It’s called the faster is slower effect a counterintuitive result studied in pedestrian flow experiments. The surprising part is that congestion doesn’t always come from insufficient effort. Sometimes too much individual urgency creates collective inefficiency. Markets have their own version. When many participants react to the same information at nearly the same time, each person may be acting rationally from their own perspective. But their combined actions can alter the environment everyone is responding to. The important variable isn’t always the quality of the decision. Sometimes it’s the interaction between decisions. A thousand sensible reactions can produce an unintuitive outcome. That’s one reason markets are not simply collections of individual choices. They are systems where choices collide. #GameTheory# #MarketStructure# #Trading# #SystemsThinking#
