Omission Bias

“Two decisions produce the same harm. One requires action; the other, standing still.”

01 / PLAINLY

What it means, plainly

People sometimes judge harm caused by acting more harshly than similar harm allowed by doing nothing.

02 / CONTEXT

A little more

In some comparisons, causing an outcome through action is judged worse than allowing it through omission. Perceived responsibility, prior norms, and intention change that asymmetry.

03 / WHY IT MATTERS

Why it matters

Inaction can look neutral and keep its costs, duties, and consequences out of the comparison.

04 / EXAMPLE

A familiar example

A manager keeps a configuration known to be flawed because changing it and being wrong would feel more blameworthy.

05 / LIMIT

What it does not mean

Acting and not acting are not always morally equivalent; duties, rights, and causation can distinguish them in relevant ways.

06 / NOTICE

Notice it in your day

For a pending choice, make two rows: act and do not act. Fill in consequences, duties, and responsibility for both at the same level of detail.

FINAL NOTE

The idea worth keeping

Compare the consequences and obligations of both paths, explicitly including the cost of not intervening.

QUESTIONS / 02

Questions people still have

Are action and omission always equivalent?

No. Duties, rights, intention, and causation can distinguish them in relevant ways.

What can change the asymmetry?

Perceived responsibility, the existing norm, and intention all shape how each path is judged.
