Decisions
Making decisions – especially large or important ones - requires a balance between deliberate and instinctive thinking.
Using an algorithm, or model, or bias can help, and often does; sometimes in the negative. These mental models prevent us from being swamped with too much information.
But expertise contributes as well. The ability to act intelligently and instinctively is possible only after time and experience have honed the skills needed to make decisions. Children who are introduced to making decisions early in life, even as simple as what colour to wear, respond better as decisions get more complex and have more consequences.
