Your brain has different networks for different types of decisions: - Analytical network for data and logic - Social network for interpersonal choices - Creative network for innovative thinking - Default network for routine operations
When you batch similar decisions, you keep the same network active. This is dramatically more efficient than constantly switching between networks. It's like running multiple errands in the same neighborhood versus driving across town repeatedly.
Dr. Elena Garza, studying decision-making in emergency rooms, found that doctors who batched similar cases made 40% fewer errors than those who switched constantly between different types of medical decisions. The batching doctors also reported feeling less exhausted despite seeing the same number of patients.
