Lecture Notes on Human Thinking and Negativity Bias

Introduction

  • Speaker: Social psychologist and "professional people watcher".
  • Topic: Exploration of how humans think and how to think better.
  • Anecdote about personal experience with academic paper acceptance and rejection.

Key Observations

  • Emotional Reactions: Positive events (e.g., paper acceptance) give a brief happiness boost, while negative events (e.g., rejection) linger longer.
  • Central Question: "Do our minds get stuck in the negatives?"

Framing Effect

  • People perceive the same information differently based on how it is framed (gain vs. loss).
  • Gain Frame: Focus on positives (e.g., glass half-full).
  • Loss Frame: Focus on negatives (e.g., glass half-empty).

Experiment 1: Surgical Procedure Framing

  • Setup: Participants split into two groups; one saw a 70% success rate, the other a 30% failure rate for a surgical procedure.
  • Result: Participants preferred the procedure when described with success rather than failure.
  • Twist: Introducing the alternate frame led to changes in perception, notably, loss frame perceptions were more resistant to change.

Experiment 2: Political Framing

  • Setup: Participants learned about a governor’s job-saving record, framed as either jobs saved or jobs lost.
  • Result: Initial frame significantly influenced perception; switching from loss to gain frame was ineffective.

Experiment 3: Mental Conversion Difficulty

  • Setup: Participants solved a math problem converting between saved and lost lives.
  • Result: Converting from gain to loss was quicker than from loss to gain, highlighting mental persistence of loss framing.

Implications and Conclusions

  • Negativity Bias: Tendency for negative perceptions and information to stick more than positive.
  • Economic Example: Consumer confidence lagged behind economic recovery post-2007 recession.
  • Personal Level: Requires conscious effort to focus on positives; gratitude practices can enhance happiness and well-being.
    • Example Exercise: Writing daily about things to be grateful for.
  • Social Impact: Focusing on positive social interactions can counteract negativity propagation.
    • Emphasis on forgiving and spreading kindness.

Practical Applications

  • Personal Practice: Encourage sharing and rehearsing positive experiences.
  • Community Efforts: Promote awareness and actions to counteract negativity bias.

Conclusion

  • Effort is required to shift our mindset from negative to positive.
  • Emphasizing positive experiences can improve overall mental health and community well-being.
