Understanding Irrationality and Decision Making

Predictable Irrationality Lecture

Introduction

  • Speaker's interest in irrational behavior started from personal experience in a hospital.
  • Encountered irrational methods used by nurses during bandage removal in the burn department.

Bandage Removal Dilemma

  • Question: Rip off bandages quickly (high intensity, short duration) vs. slowly (low intensity, long duration)?
  • Nurses in the burn department preferred the quick removal method.
  • Speaker suggested trying a slower method to reduce pain intensity.
  • Nurses believed they understood the best method for patient pain minimization.

Experimental Method

  • Upon university study, learned about the experimental method to test questions.
  • Conducted experiments to simulate pain experiences and gather data on pain perception.

Key Findings on Pain

  • Found that pain is encoded more by intensity than duration.
  • Longer duration with lower intensity would have been less painful.
  • Trend of improvement (starting at face to legs) would have reduced pain.
  • Breaks would have helped patients recuperate from pain.

Broader Implications

  • Began questioning if irrational decisions are common in other areas.
  • Extended exploration to other irrational behaviors such as cheating.

Study on Cheating

  • Initial interest sparked by Enron scandal.
  • Explored whether cheating was limited to a few individuals or more common.

Cheating Experiment

  • Simple math problems test: insufficient time, participants tempted to cheat.
  • People claimed to solve more problems when they could shred their answers.
  • Most cheated slightly rather than extensively.

Economic Theory vs. Reality

  • Economic theory: Cheating is a cost-benefit analysis.
  • Study found insensitivity to economic incentives (probability of being caught, punishment severity).

Personal Fudge Factor

  • People balance cheating with moral self-perception.
  • Greater distance from cash (e.g., tokens) increased cheating.
  • Social influences on cheating: In-group behavior increased, out-group behavior decreased.

Implications for Stock Market

  • Distance from real money through financial instruments may increase cheating.
  • Social environments and distorted realities contribute to market behaviors.

Conclusion

  • Behavioral economics highlights flawed human intuitions.
  • Importance of testing intuitions in personal, business, and policy contexts.
  • Speaker's personal lesson on testing intuitions learned from nurses' resistance to experimentation.

Final Thoughts

  • Advocates for systematic experimentation to refine our understanding and improve decision making.
