Final answer:
Jameson is in a state of subconsciousness as he drives home from work automatically. This state allows him to perform routine tasks without active conscious thought, relying instead on unconscious mechanisms.
Step-by-step explanation:
The state that Jameson is in when he drives home from work out of habit, without consciously thinking about it, is known as subconsciousness. When we engage in tasks we've done numerous times, such as driving a familiar route home, our brain relies on unconscious mechanisms to perform these habitual activities without the need for active, conscious thought. This allows us to operate on "autopilot," which is not only efficient but also conserves mental energy for other tasks that require more conscious effort. Our daily lives include various states of consciousness including wakefulness, sleep, daydreaming, and the subconscious actions like the one Jameson experienced. Kahneman discusses that while we may engage in effortful thinking when processing new or complex situations, many of our routine actions are guided by heuristics; these allow us to perform tasks quickly and with little conscious thought.
