Introduction

• Speaker: Ben Newell, Professor of Cognitive Psychology, UNSW Sydney
• Event: UNSW Center for Ideas
• Guest: Daniel Kahneman
• Focus: Launch of Kahneman's book Noise
• Acknowledgements: Traditional custodians of the land, elders past and present, Aboriginal and Torres Strait Islander communities

About Daniel Kahneman

• Nobel Prize in Economics (2002) for work with Amos Tversky on human judgment and decision making
• Studied attention, memory, well-being, counterfactual thinking, behavioral economics
• Author of Thinking, Fast and Slow (2010)
• Current Position: Eugene Higgins Professor of Psychology, Princeton University

Discussion Highlights

Nobel Prize in Economics

• Luck and Influence: Serendipity in economics and decision theory; influence on Richard Thaler and behavioral economics
• Rationality: Defined and impractical for human minds; better to think of rationality as an intellectual exercise than a practical one

System One and System Two (Thinking, Fast and Slow)

• Systems Defined: System 1 (fast, automatic) vs. System 2 (slow, effortful)
• Public Perception: Oversimplification and personification of systems can mislead
• Practical Utility: Awareness of different thinking processes can help but will not drastically change human behavior

New Book: Noise

• Definition of Noise: Unwanted variability in judgments; different from bias
• System Noise: Differences in judgments across individuals; crucial in contexts like judicial sentencing
• Types of Noise: System noise, level noise, pattern noise (stable and transient)
• Addressing Noise: Requires structural change in organizations; statistical concept making it challenging to grasp

Intuition in Judgment

• Should be informed, disciplined, and delayed
• Delaying intuition helps gather accurate information before forming judgments
• Example: Structured interviews with delayed intuitive judgment found more valid

Algorithms and Human Judgment

• AI in Judgment Tasks: Superior due to lack of noise; not ready for all tasks but progressing
• Human-AI Interaction: Combining human insight with algorithms proves effective; potential revolutionary impact on decision making

Improving Psychological Science

• Replication Crisis: Greater methodological rigor now; improvement in psychology's scientific standards
• Behavioral Economics' Impact: Useful for marginal adjustments, not solutions for major societal issues like climate change

Final Thoughts

• Behavioral insights useful but limited in scope
• Major societal changes require more than nudges; need systemic, policy-level changes

Conclusion and Acknowledgements

• Encouragement to read Noise
• Thanks to Daniel Kahneman and the UNSW Center for Ideas for organizing the event
