Hanlon's Razor: Most Slights Were Never Aimed at You

Your manager schedules a meeting about your project and does not invite you.

Within about four seconds, most people have constructed a fairly complete story. There was a conversation you weren't part of. A decision has been made about your work, or about you. Perhaps someone raised concerns. Perhaps this is how it begins.

There is a competing explanation, and it is much duller. They built the invite list from an old thread, or from a calendar group that was set up before you joined, and did not notice you were missing.

Both explanations fit the facts perfectly. Hanlon's Razor says to prefer the second one: never attribute to malice that which is adequately explained by carelessness, incompetence, or someone simply not thinking about you very much.

It sounds like advice about being charitable. It is better understood as advice about being accurate.

Why it works: it is really arithmetic

The razor is not a request to be nice. It follows from counting assumptions, which makes it a direct application of Occam's Razor.

Work out what the malicious explanation actually requires:

• Your manager decided to exclude you (intent)
• They understood that excluding you would have the effect it did (competence)
• Others went along with it, or at least did not object (coordination)
• Nobody mentioned it to you (secrecy, sustained)

That is four separate things, each of which could be false.

Now the careless explanation: someone reused a list without checking it. One assumption. And it is an assumption about a behaviour that is enormously well attested — people reuse lists, forget names, and act without thinking through consequences constantly, including you and me.

Independent probabilities multiply, so a four-assumption explanation is substantially less likely than a one-assumption explanation covering the same facts. The razor is not generosity. It is what you get when you count properly.

There is a second reason it holds, which is about the sheer supply of the two ingredients. Deliberate, coordinated, sustained malice is genuinely rare, because it is effortful and risky. Distraction, overload, and not-thinking-about-you are in essentially unlimited supply. When an outcome could come from either, the abundant cause is the better bet.

Why our minds default the other way

If the arithmetic is that clear, why is malice the instinctive first read? Because of an information asymmetry that is structural rather than psychological.

You experience the consequence completely. You know exactly how it felt to be left out — the whole weight of it.

You experience their circumstances not at all. You cannot see that they were assembling that invite between two other meetings, on a day when something at home had gone wrong, using a list someone else made.

So you have vivid data about the effect and nearly none about the cause. And an effect that lands on you personally feels aimed, because the feeling of being targeted is generated by the impact, not by evidence of intent.

This is the same machinery as the fundamental attribution error — the tendency to explain other people's behaviour by their character while explaining our own identical behaviour by our circumstances. When you forget to invite someone, you know it was an oversight, because you have full access to your own overloaded day. When someone forgets you, all you can see is the omission.

Recognising that the asymmetry is informational rather than a personal failing makes the razor much easier to actually apply. You are not being asked to think better of people. You are being asked to notice that you are missing half the data.

Where the razor stops applying

A treatment that presented this as a universal rule would be doing you a disservice, because the razor has clear limits and knowing them is what makes it usable.

Repetition retires it. A single omission is plausibly an oversight. The same omission for the fifth time, after being raised, is a pattern — and patterns are evidence about intent in a way single events are not. The razor governs your first interpretation, not your permanent policy.

Systematic benefit retires it. If the "mistakes" consistently favour the same party, that consistency is data. Genuine carelessness is randomly distributed; errors that always fall the same way are not obviously errors.

Scale changes the calculation. For an individual, incompetence is the abundant explanation. For institutions with resources, review processes, and clear incentives, "we didn't think it through" becomes less plausible the larger the stakes and the more times it recurs. And note that incompetence at scale can be just as harmful as malice — the razor tells you about the cause, not about how much you should mind.

It is not a shield against consequences. "They didn't mean it" explains an action; it does not undo it. Someone who repeatedly causes harm carelessly still needs to stop, and treating the razor as a reason to keep absorbing damage is a misreading of it. Diagnosis and response are separate steps.

It should never suppress a real concern. Used badly, the razor becomes an instrument for dismissing people who report a genuine pattern. If someone tells you they are being treated unfairly, "probably just a mistake" is a hypothesis to test, not a verdict to hand down.

Held properly, the value is in what it buys you: fewer arguments started over things that were nobody's decision, and a clearer signal when something genuinely is a pattern — because you are not spending your suspicion on the routine chaos of people who are simply busy and not thinking about you.
