Does this sound like the set of challenges you might be facing?
- I’m frozen on a health call because the rare bad thing that could come from acting terrifies me, even though the slow harm of doing nothing is probably far bigger
- “Not deciding yet” feels so passive and harmless, but when I try saying it out loud as what it really is
- I notice I’d feel devastated if a choice I made went wrong, but strangely okay if the exact same bad thing happened because I just sat on my hands
- Some part of me believes that as long as I didn’t do anything, I’m off the hook for whatever happens next
- I’m sure about my read on this, but I only ever notice the things that confirm what I already think
Practices that may help
- Omission Bias — Why Doing Nothing Feels Safer Than Acting
Omission bias, documented by Spranca, Minsk, and Baron (1991), is the tendency to judge harmful inactions as less morally blameworthy than equally harmful actions — and to choose inaction even when acting would produce better outcomes. It is driven by the moral asymmetry between doing and allowing, but it systematically underweights the real costs of not acting. - Apply the vaccination model: compare population outcomes, not individual paths
Ask: if 1,000 people faced this choice, what’s the total harm from universal inaction vs. universal action?
Omission Bias — Why Doing Nothing Feels Safer Than Acting - Reframe the inaction as a positive act
Describe what you’re doing by not acting — make the omission into a commission.
Omission Bias — Why Doing Nothing Feels Safer Than Acting - Apply the outcome equivalence test
Ask: if the same harm resulted from action vs. inaction, which would you prefer? Divergence reveals the bias.
Omission Bias — Why Doing Nothing Feels Safer Than Acting - Identify that inaction is also a choice with moral weight
Remind yourself that doing nothing is still a decision you’re responsible for.
Omission Bias — Why Doing Nothing Feels Safer Than Acting - Notice which data you selected — and which you ignored
Your conclusions are built on a sample of the available data — ask what the sample excluded.
The Ladder of Inference - Survivorship Bias: Learning from What You Can’t See
Survivorship bias is the error of drawing conclusions only from the cases that made it through a filter — winners, survivors, visible successes — while the failures that never appear are silently excluded. The clearest historical example is Abraham Wald’s WWII aircraft study: the military wanted to armor the bullet holes they saw on returning planes; Wald showed they should armor where they saw no damage, because planes hit there didn’t return. - Actively seek out the failures you aren’t seeing
Look for the people who tried the same thing and didn’t make it through.
Survivorship Bias: Learning from What You Can’t See - Base-Rate Neglect: Why We Ignore the Odds
Base-rate neglect is the tendency to underweight or ignore prior probabilities (how often things happen in general) when vivid, specific information is available. Identified by Kahneman and Tversky, it is one of the most robustly replicated biases in judgment research, and it leads to systematic overconfidence in predictions about specific cases. Correcting it requires actively looking up or estimating base rates before evaluating individual information. - Always identify the denominator when evaluating risk or success
When a number or story is striking, ask: "Out of how many total cases?"
