Study Notes
Two Systems
- System 1 operates automatically and quickly, requiring little effort, while System 2 involves effortful mental activities and complex computations.
- System 1 generates complex ideas; System 2 organizes thoughts sequentially and is associated with agency and choice.
System 1 Functions
- Capable of innate skills shared with animals, allowing for perception and quick reactions to stimuli, such as recognizing threats.
Shared Control of Attention
- Both systems control attention; System 1 reacts to stimuli involuntarily, prompting System 2 to engage voluntarily.
Gorilla Experiment
- A video shows people counting basketball passes while a gorilla appears briefly, illustrating selective attention in action.
Experiment Results
- Approximately half of the viewers do not notice the gorilla, demonstrating how focused tasks can lead to "inattentional blindness."
Mind's Blindness
- The gorilla study highlights our ability to overlook obvious stimuli, and our ignorance of this blindness.
Conclusion of the Experiment
- Attention is essential for detecting surprising stimuli; surprise directs focus and prompts cognitive processing.
Active Systems
- Both System 1 and System 2 are active whenever we are awake.
System Activity Levels
- System 1 operates automatically; System 2 remains mostly in a low-effort mode except for challenging tasks.
Function of the Systems
- System 1 makes suggestions (intuitions, feelings) to System 2, which can endorse or modify these suggestions based on logical considerations.
System 2 Functions
- Activated by unexpected events that conflict with System 1's model of the world and assists in monitoring behaviors and controlling impulses.
Summary of Functions
- System 2 takes over during complex situations, but most thoughts and actions originate from System 1.
System 1's Proficiency
- Generally accurate in assessing familiar situations, quick to respond with appropriate reactions despite occasional biases.
System 1's Limitations
- Often substitutes easier questions for the original ones and lacks understanding of logic; cannot be deactivated at will.
Self-Control and System 2
- System 2 is responsible for self-control, managing impulses arising from System 1.
Cognitive Illusions
- These are errors in thinking or memory based on System 1's operations and can persist despite awareness of their inaccuracy.
Overcoming Cognitive Illusions
- Preventing intuitive errors requires increased attention and effort from System 2, though continuous vigilance can be impractical.
Compromise Solution
- Learning to recognize situations where errors are likely can help mitigate significant mistakes, especially in high-stakes scenarios.
Reality of Systems
- Systems 1 and 2 are conceptual; there are no specific brain regions dedicated to either "system."
Systems and Mental Effort
- Only System 2 can perform tasks requiring effort and self-control; it can operate under rules and is better at comparing multiple attributes.
Pupil Response and Effort
- Pupil dilation indicates mental effort, with larger dilations occurring during complex tasks.
Skill and Energy Efficiency
- As skills improve, less energy is required; highly skilled individuals use fewer brain resources for problem-solving.
Task Sets in System 2
- System 2 can prioritize tasks and override habitual responses.
Cognitive Task Switching
- Switching tasks is challenging, particularly under time pressure, leading to inefficient performance.
Avoiding Mental Overload
- Tasks are divided into simpler steps, engaging long-term memory to manage working memory limitations.
System 2's Natural Speed
- Even when inactive, System 2 consumes energy in monitoring environments and random thoughts.
Self-Control and Mental Effort
- Self-control and cognitive tasks draw from a shared energy pool; exertion in one affects the capacity for the other.
Ego Depletion Phenomenon
- Effortful tasks can lead to lower willingness for subsequent challenges due to mental fatigue.
Studies on Self-Control
- Challenging cognitive tasks alongside temptations increase the likelihood of succumbing to those temptations.
Glucose and Cognitive Effort
- The nervous system requires significant glucose for mental activities; replenishing glucose can reduce ego depletion's effects.
Memory and Systems
- Memory functions mainly belong to System 1, but System 2 can initiate a deliberate search for relevant information.
Characteristics of Systems
- System 1 is instinctual; System 2 requires reasoning and is often lazy.
Cognitive Ease
- Continuous mental computations assess one’s environment, guiding the need for System 2's effort based on perceived ease.
Levels of Cognitive Ease
- Cognitive ease indicates a perceived lack of threats or demands; cognitive strain signals problems needing more effort from System 2.
Inducers of Cognitive Strain
- Poorly formatted instructions or personal discomfort can create cognitive strain, leading to reduced efficiency.
Inducers of Cognitive Ease
- Positive stimuli, such as good moods or humor, enhance cognitive ease and receptivity.
Effects of Cognitive States
- Cognitive ease leads to superficial, intuitive thinking; strain fosters vigilance but can diminish creativity.
Illusions of Remembering
- Familiarity creates an illusion of past experience, influencing perception and decision-making.
Repetition's Impact on Familiarity
- Repeated exposure to stimuli can create comfort and familiarity, facilitating favorable responses.
Mood Influence on System 1
- Negative moods can hinder intuition, whereas positive moods can enhance creativity but reduce vigilance.
Evolutionary Link of Emotion and Cognitive Ease
- Positive emotions encourage relaxation and attentiveness, while negative emotions trigger wariness and increased vigilance.

Description
Explore the concepts from chapters 1-3 and 5 of Daniel Kahneman's 'Thinking Fast and Slow'. This quiz focuses on the dual systems of thinking: the fast, automatic System 1 and the slower, more deliberate System 2. Test your understanding of how these systems influence decision-making and cognitive processes.
