Omission Bias
- Filed under
- Too Much Information
The charge
We judge harmful actions as worse than equally harmful inactions, so doing nothing can feel morally safer even when outcomes are just as bad or worse. In decisions, passivity often gets a free moral discount.
How it operates
Acts create a stronger sense of agency and blame than omissions. Because regret and responsibility feel heavier for commissions, people often prefer inaction.
Logged incidents
- Incident 01
A company delays fixing a known security weakness because an active change feels riskier than leaving the status quo in place.
- Incident 02
An investor keeps cash during inflation because buying a losing asset would feel like a mistake, even though inaction also destroys value.
- Incident 03
A manager avoids giving hard feedback, preferring the damage from non-action over the discomfort of an explicit intervention.
What to watch for
Ask yourself: 'Would I judge this differently if the same harm came from action instead of inaction?'
Recommended action
Use an outcome-based accountability check: compare expected harms of acting and not acting side by side. A decision matrix that treats omissions as real choices is the practical fix.
