In his seminal book “Thinking, Fast and Slow,” Daniel Kahneman describes two systems that drive human cognition: System 1, which operates automatically and quickly with little effort, and System 2, which allocates attention to more challenging mental activities requiring deliberate focus. This dual-process theory has profound implications not just for understanding human behavior, but for designing intelligent systems that must balance immediate responsiveness with strategic foresight. Similar “plan vs. act” decompositions show up in other domains too — for example, robotics and autonomous driving often separate a slower planning layer (setting goals and constraints over longer horizons) from faster control and execution loops, and modern LLM agents frequently pair deliberate planning with rapid, step-by-step tool use and reaction.

在其开创性著作《思考，快与慢》中，Daniel Kahneman描述了驱动人类认知的两个系统：System 1，它自动且快速地运行，几乎不费力气；以及System 2，它将注意力分配到需要刻意专注的更具挑战性的心理活动上。这种双过程理论不仅对理解人类行为具有深远意义，而且对设计必须在即时响应与战略远见之间取得平衡的智能系统也具有重要意义。类似的“计划与执行”分解也出现在其他领域——例如，机器人技术和自动驾驶通常将较慢的规划层（在更长的时间范围内设定目标和约束）与较快的控制和执行循环分离开来，而现代LLM智能体也经常将深思熟虑的规划与快速、逐步的工具使用和反应结合起来。
