Attention and Effort (System 1 and System 2)
In Kahneman’s account, System 2 requires effort and often accepts a System 1 response without further examination. Self-control and demanding tasks call for more sustained attention.
THE IDEA
SPEAKING OF SYSTEM 1 AND SYSTEM 2
"He had an impression, but some of his impressions are illusions."
"This was a pure System 1 response. She reacted to the threat before she recognized it."
"This is your System 1 talking. Slow down and let your System 2 take control."

ATTENTION AND EFFORT
In the unlikely event of this book being made into a film, System 2 would be a supporting character who believes herself to be the hero. The defining feature of System 2, in this story, is that its operations are effortful, and one of its main characteristics is laziness, a reluctance to invest more effort than is strictly necessary. As a consequence, the thoughts and actions that System 2 believes it has chosen are often guided by the figure at the center of the story, System 1. However, there are vital tasks that only System 2 can perform because they require effort and acts of self-control in which the intuitions and impulses of System 1 are overcome.
When to use it
Negotiating a contract: Use System 2 to carefully analyze terms and anticipate long-term consequences.
Driving in heavy traffic: System 1 may handle routine actions, while an unfamiliar maneuver can call for deliberate System 2 attention.
Making a strategic business decision: Engage System 2 to evaluate data, consider multiple perspectives, and resist biases.
Learning a new skill: Initially requires effortful System 2 practice, which gradually becomes automatic under System 1.
FROM THEORY TO EVERYDAY LIFE
In practice
Financial Decision-Making
When evaluating a complex investment, a person notices an initial System 1 impression, then uses System 2 to check the numbers and compare alternatives. This creates an opportunity to examine assumptions and errors.
Emotional Reactions in Arguments
During a heated argument, an immediate emotional reaction is a System 1 response. Taking a moment to breathe and reflect (System 2) can prevent escalation and lead to a more constructive discussion.
A MOMENT TO REFLECT
Put it to work.
In what situations do you tend to rely on System 1 when System 2 would be more appropriate?
How can you recognize when your System 2 is being lazy and letting System 1 take over?
What strategies can you use to engage System 2 more effectively in high-stakes decisions?
