It appears to me that much of the decision making that goes on in Wall Street is System 1 thinking. It operates mainly by intuition. Decisions are made automatically and quickly with little or no time for thoughtful reflection. System 2 thinking is serious thought. It is deliberate and requires concentration. System 2 thinkers are naturally patient. For System 2 thinking to work effectively, you must allocate time for deliberation and, yes, even meditation.
