Hanlon's Razor
Never attribute to malice what is adequately explained by incompetence.
- Never attribute to malice what is adequately explained by incompetence.
- Operating: Someone in another department didn't include your team in a key decision.
- Investing: A portfolio manager underperforms.
- Everyday life: Someone didn't text you back.
First written down by Robert J. Hanlon in 1980, though earlier versions exist in Goethe and Napoleon. It's one of the most useful razors in everyday business life.
When something goes wrong and someone seems to have wronged you, the instinct is to assign motive. They did this on purpose. They want to undermine me. They're playing politics.
Hanlon's Razor says: probably they didn't. Most of the bad things that happen to you at work are not someone trying to hurt you. They're someone being busy, distracted, untrained, badly briefed, working with bad information, or just not very good at their job. The world has vastly more incompetence than malice, and incompetence produces almost identical-looking outcomes most of the time.
This matters because the two interpretations produce very different responses. The malice interpretation triggers escalation, lawyers, formal complaints, frosty meetings. The incompetence interpretation triggers a polite note, a clarifying conversation, a process fix. The first set is expensive. The second set is cheap. And the second set is right 90% of the time.
Hanlon's Razor isn't an instruction to be naive. Real bad actors exist. But the default assumption matters because most people you'll deal with are not bad actors, and treating them as if they are makes them defensive and breaks the relationship. The cost of being wrong about malice (when it's actually incompetence) is high. The cost of being wrong about incompetence (when it's actually malice) is usually lower, because the malicious person will reveal themselves over time.
A useful practical rule: when something looks deliberately hostile, give it one Hanlon test. "Could this be explained by busyness, miscommunication, missing context, or simple error?" If yes, respond as if it is. If the same pattern repeats three times, reconsider.
The same logic applies to your own behaviour. Most of the times you've let people down, you weren't being malicious. You were tired, behind, badly briefed, or didn't know. Give the same charity to others.
Examples in the wild
Someone in another department didn't include your team in a key decision. The malice read: they want to cut you out. The Hanlon read: they forgot, or didn't know who to add. The second is true ~90% of the time and your response (a polite note, not an escalation) costs nothing.
A portfolio manager underperforms. The malice read: they're skimming, lying, or chasing their own incentives. The Hanlon read: they're executing the wrong strategy, anchored on a bad framework, or having a run of bad luck. The second is more common and easier to fix.
Someone didn't text you back. The malice read: they're ignoring you. The Hanlon read: they saw the notification, meant to reply later, and forgot. 95% of the time it's the second.
Hanlon's Razor is one of the mental models we apply through real cases inside the Pareto MBA — a part-time program for professionals who want to think clearly about business.
