Hanlon's Razor: Malice or Simple Mistake?

A colleague has not replied to your email for days. The car in front of you in traffic changes lanes without signaling. Your manager acts as if they never heard the idea you raised in the meeting. In all these moments, the same question arises in our minds: “Are they doing this to me on purpose?” More often than not, the answer is far more mundane and far less personal than we imagine. The person across from us is probably not even thinking about us; they have simply forgotten, distracted themselves with something else, or failed to do their best under pressure.

It is precisely at this point that a mental tool comes into play: Hanlon’s Razor. The rule is extremely short and simple: “Do not attribute to malice that which can be adequately explained by stupidity.” This seemingly simple sentence offers us a surprisingly powerful perspective on human relationships, professional life, and even the design of complex systems. ^【1】

In philosophy, the term “razor” refers to a simple principle that helps us cut away unnecessary complexity when thinking about an issue. Occam’s Razor is the most famous example: “When two theories explain the same phenomenon equally well, the simpler one should be preferred.” Hanlon’s Razor operates on similar logic but focuses on human behavior rather than physics or logic. When explaining an event, we usually have multiple possible causes: malice, negligence, fatigue, lack of information, time pressure, simple inattention… The razor tells us to place the most complex and heaviest accusation—malice—at the bottom of the list. Because statistically and through everyday observation, people are more often hurried, distracted, or uninformed than malicious.^【2】

Although the exact origin of the phrase remains unclear, it is known that the expression circulated in computer culture and internet forums in the 1980s and gradually became associated with the name “Hanlon.” Regardless of who first said it, the idea itself is much older, grounded in a centuries-old observation about how humans judge one another. ^{【3】 【4】}

We need to remember this razor, because our minds naturally operate in the opposite direction. The human brain tends to produce quick explanations in the face of uncertainty, and these explanations are usually the first that come to mind—the ones with the most “story value.” When someone harms us or lets us down, the story “they meant to hurt me” is far more memorable and dramatic than “they were distracted.” The mind prefers meaningful, causal narratives over dull explanations.

Another reason is our tendency to center ourselves. When evaluating someone else’s behavior, we tend to overestimate how much it has to do with us. In reality, we occupy far less space in the other person’s mind than we imagine; they have their own concerns, their own fatigue, and their own agenda. The behavior we interpret as directed at us is usually not a deliberate attitude toward us but rather a byproduct of their internal world.

Moreover, the weight we give to negative information reinforces this tendency. We remember negative comments or behaviors far more intensely and for much longer than positive ones. Therefore, when someone ignores us, the explanation that this was a deliberate choice sticks more easily and remains longer in our minds.

When we apply Hanlon’s Razor to everyday life, we realize that many tensions never needed to exist. If a friend forgets your birthday, it is far more likely due to a busy period in their own life than a lack of care for you. If a colleague interrupts you in a meeting, it is probably not because they are belittling you, but because they feared losing their train of thought and reacted impulsively.

Similar examples abound in professional life. An unanswered email usually means the recipient’s inbox is overflowing, not that the sender is unimportant. A decision made on a project without consulting you may stem not from a desire to exclude you but from the decision-maker’s pressure to choose the fastest option. A customer service representative’s cold demeanor may arise not from personal hostility but from exhaustion after a string of similar complaints that day.

The common thread in these examples is this: when explaining someone else’s behavior, we always have multiple reasonable scenarios available, yet we tend to choose the worst one. Yet almost always, a far more ordinary, far less dramatic explanation exists.

Hanlon’s Razor is a powerful tool, but it is not an unlimited get-out-of-jail-free card. The rule itself implies a boundary: the phrase “can be adequately explained” sets a limit. When certain behaviors recur, form a pattern, or consistently benefit the person performing them, the “simple mistake” explanation begins to fall short. If someone forgets you once, that is inattention; but if the same person systematically forgets you and consistently behaves in ways that harm you “by accident,” ignoring this pattern becomes naivety.

Here a second criterion comes into play: who benefits from the outcome? If a mistake consistently advantages the person who made it, and this advantage repeats in the same direction, the likelihood of coincidence diminishes. Thus, the razor does not tell us to “always assume the best intent”; it tells us to “try the simplest explanation first, and stay there unless a pattern or benefit forces you elsewhere.” This distinction is especially important in environments with unequal power dynamics. When systemic discrimination, institutional neglect, or repeated abuse patterns are involved, dismissing the issue as “someone was just distracted” distorts the razor’s purpose. The razor is designed to interpret individual, one-off events; it is not an excuse to ignore systemic patterns.

This distinction recalls a familiar logic from the world of engineering. When a failure occurs in a complex system, the first question is almost never “Who did this on purpose?” Failure analysis begins by eliminating the most probable and most ordinary causes: a connection may have loosened, a component may have exceeded its tolerance, a software update may have triggered an unexpected interaction. The possibility of intentional interference is considered only at the very end, after all ordinary explanations have been exhausted. The reason is not naivety but efficiency. Ordinary causes are statistically far more common, and eliminating them first is the fastest way to find the real problem. The same logic applies to human relationships: placing malice first often leads to incorrect diagnoses and unnecessarily opens the door to conflict. Starting with the question “Could this be a simple glitch?” is both more accurate and less damaging to relationships. Yet even in engineering, at some point the list of possibilities narrows, and recurring, patterned failures demand special investigation. The same logic applies to human relationships: the razor sets the initial assumption, but it does not have the final word.

The most practical way to make Hanlon’s Razor a habit is to ask yourself a small question before reacting: “Is there at least one plausible explanation for this behavior that does not involve malice?” More often than not, the answer is yes—and this single question can prevent an unnecessary outburst, a hurtful message, or a damaged relationship. In addition, delaying your response helps. Instead of immediately judging or sending a message, waiting a few hours or even a night allows the initial dramatic interpretation to give way to a calmer evaluation. Asking the person directly is often overlooked but highly effective; saying “I’m curious what you thought about this” usually immediately disproves the worst-case scenario.

Finally, pay attention to patterns. The razor applies to single events; but if the same behavior repeats many times and always benefits the same person, being a careful observer is healthier than being naive.

Hanlon’s Razor teaches us not about other people, but about our own minds: we have a tendency to choose the most dramatic explanation in the face of uncertainty, and this tendency often misrepresents reality. Reserving malice as a last resort makes our relationships healthier and frees our minds from unnecessary burdens. Of course, this does not mean we should close our eyes and assume good intent in everything; it simply reminds us to pause before judging and consider the simplest possibility. More often than not, the person across from us does not want to hurt us; they are simply caught up in the rush of their own life and cannot be as attentive as we notice. Remembering this brings a little more peace to both us and the people around us at the end of the day.
