There are two systems that govern decision making - System 1 and System 2. System 1 is automatic, affective, and relies on mental shortcuts to quickly propose intuitive answers. System 2 is slower, more effortful, conscious, and rule-based; it can overrule System 1 when necessary. While the systems usually interact seamlessly, sometimes they can compete by coming to different conclusions, draining energy. The document advocates training System 1 to inform System 2 for a seamless interaction that gains energy, as opposed to a competing interaction that drains it.
