A Few More Details

Optimism Bias

Optimism Bias describes our tendency to overestimate our likelihood of experiencing positive events and underestimate our likelihood of experiencing negative events.

Why It Happens

Our brains are wired to:

  • Protect our mood and motivation by focusing on the positive.
  • Take mental shortcuts when predicting future events.
  • Rely on personal experiences over statistical probabilities.

It’s a form of motivated reasoning—we want to believe things will go well, so we find reasons to believe they will.

Why It Can Be Good

  • Boosts morale: Helps us feel hopeful and energized about the future.
  • Encourages risk-taking: Can lead to innovation and bold leadership.
  • Builds resilience: Keeps us going even after setbacks.
  • Promotes vision: Inspires others to believe in a better outcome.

Why It Can Be Bad

  • Leads to poor planning: Underestimating time, cost, or risk.
  • Prevents contingency planning: “We won’t need a Plan B.”
  • Contributes to complacency: “We’ve never had a problem before, so we won’t in the future.”
  • Overlooks warning signs: Dismissing data or feedback that suggests danger or failure.

How It Shows Up in Leaders

  • Setting unrealistic deadlines or budgets based on best-case scenarios.
  • Skipping risk assessments or fail to account for possible failure modes.
  • Dismissing concerns raised by team members because you “just don’t see it going wrong.”
  • Pushing ahead too quickly on new initiatives without stakeholder alignment or proper testing.

How It Shows Up in Teams

  • Crews rush tasks assuming everything will go fine.
  • They don’t double-check or follow safety protocols they’ve “never needed.”
  • They dismiss previous incidents as flukes, not lessons.
  • They say things like: “That’ll never happen to us.” “We’ve done it this way a hundred times—it’s fine.” “It’s just a small job, what could go wrong?”
