A strategy that worked in the past can become a trap when we start applying it to everything. Not because it’s inherently bad, but because we stop questioning whether it’s truly the best solution for the problem at hand. And yet, our tendency to seek patterns and shortcuts leads us precisely to replicate what we already know.
Obviously, while these strategies are working, we hardly realize that we are using them, so they become our “normal” way of reacting.
Until, in a certain situation, they stop working. Then something curious usually happens: instead of rethinking the strategy, we increase the dose. If control hasn’t worked, we control more. If explanation hasn’t worked, we give more explanations. If effort hasn’t been enough, we demand even more of ourselves.
It’s like trying to open a stuck door by pushing harder and harder, without stopping to see if we could perhaps open it by pulling. The law of the hammer invites us to make precisely that pause: before asking ourselves what we can do to solve a problem, it’s worth asking ourselves if we’re looking at the problem correctly.
The origin of the hammer
In 1964, philosopher Abraham Kaplan warned that we tend to formulate problems in a way that requires precisely the techniques we have already mastered. He called it “the law of the tool.” Essentially, he said that “If you give a child a hammer, it will seem to them that everything they find needs a hammer.”
Later, psychologist Abraham Maslow popularized a very similar formulation, pointing out that when the only tool available is a hammer, it’s tempting to treat everything as if it were a nail. Hence, the idea became known as Maslow’s hammer.
The problem isn’t having a hammer, but using it for everything
Having a familiar tool can be incredibly useful. We all need to automate certain procedures so we don’t have to rethink every decision and every step from scratch. If every small problem required analyzing all the existing possibilities, our mental capacity would quickly become overloaded, leaving us with no “bandwidth” for other, more important things.
The problem arises when familiarity stops being helpful and becomes the solution to everything. And that can happen to us in countless everyday situations. For example, when we resort to the same arguments in the face of conflict, something that, instead of resolving it, only makes it worse. Or when our response to stress is to work even harder, which will ultimately make it chronic.
However, the same applies to our strengths. A highly rational person might try to resolve a situation requiring empathy with a barrage of logical reasoning. Someone accustomed to organizing everything might respond to uncertainty by making even more plans. A person who has learned to be independent might try to solve any difficulty without asking for help, even if it’s clear they can’t do it alone.
The tool isn’t bad. It can be excellent for some things, but not for others.
When a solution that worked starts to work against us
Psychologists have spent decades studying something closely related to this phenomenon: the Einstellung Effect; that is, the tendency to use a known strategy even when there is a simpler or more appropriate one.
One of the classic experiments was conducted by Abraham Luchins in 1942. Participants had to solve problems using containers of varying capacities to obtain specific quantities of water. After repeatedly practicing a particular strategy, many continued to use it when faced with a problem that could be solved more simply.
The interesting thing is that having learned a correct strategy for solving problems could make it harder to solve the next problem.
It is a rather revealing paradox because it indicates that experience, which we normally consider an advantage, can become a disadvantage when it makes us rigid and prevents us from seeing the current situation.
Subsequent research linked this effect to processes such as functional fixedness. This concept refers to how our past experiences can cause certain solutions to automatically appear in our minds, preventing us from even considering other possibilities.
The hammer as identity
Although the “hammer” is generally perceived as a tool, in some cases it can also become a way of understanding who we are. Thus, a person might identify with “the one who always solves problems,” “the one who stays calm through thick and thin,” “the responsible one,” “the one who always knows what to do,” “the strong one,” or “the one who always helps.” When a strategy works for a long time, we are likely to end up incorporating it into our identity.
Changing tools then becomes more difficult, because it’s no longer simply a matter of finding another solution or modifying behavior, but of “giving up” a part of ourselves with which we have become identified. Therefore, it’s worth remembering that being competent or intelligent consists, above all, of being mentally flexible.
How to stop treating everything like a nail?
It’s not about distrusting our usual strategies, as many of them can still be useful. The issue is recognizing when we’ve gone from using a tool to depending on it, and when it becomes a filter through which we see almost everything.
1. Separate the problem from your explanation of the problem
Before looking for a solution, try to describe what’s happening without adding a cause or jumping to a conclusion. The difference may seem small, but when we confuse the facts with our interpretation, we end up looking for solutions based on an explanation that might not even be correct. We must first focus on describing what is happening, with an open mind to all possibilities.
2. Find an explanation that contradicts your first hypothesis
When we find an explanation that fits what we see, we stop searching. If someone is distant, we think they’re angry. If our child gets bad grades, we assume they’ve lost interest. If we’re irritable, we conclude we’re stressed.
Try doing the opposite; that is, look for two other alternative explanations that could also explain the events. This isn’t about making excuses or falling into relativism where everything can mean anything, but about introducing an element of verification against our own bias. If we only look for data that confirms our initial interpretation, any tool we use afterward will be built upon it.
3. Ask what kind of problem you have before deciding how to solve it
Not all problems are the same. Some require more information before acting, while others demand a quick decision. Still others require accepting a situation we cannot change. Some need boundaries, while others need negotiation. Some problems are solved by acquiring a skill, while others worsen precisely when we try to solve them too quickly.
Therefore, before acting, it’s best to think about the type of problem you have. It might seem like a theoretical question, but I assure you that this exercise will drastically change your response. If you confuse a problem of uncertainty with one of lack of information, you could spend hours searching for data when what you need is to learn to live with that not knowing. If you confuse a problem of limits with one of understanding, you might end up endlessly explaining something that needs a clear consequence. Consequently, clarify the problem before looking for a solution.
4. Ask yourself what response you apply out of habit
When you’ve been dealing with the same problem for a while, try to identify your automatic reaction: Do you control it? Do you insist? Do you avoid it? Do you explain? Do you try harder? Do you look for information? Do you try to please?
Then ask yourself what would happen if you did the exact opposite. This doesn’t mean you have to do it; the goal is to assess to what extent you’re acting out of choice or simply following a familiar pattern. Sometimes, imagining another alternative is enough to discover that you’ve been fixated on a single answer for a long time.
5. Assume a psychological distance
When something affects us personally, our interpretation becomes more rigid. We don’t see all the options because we’re too caught up in defending our position, anticipating consequences, or protecting ourselves from what we feel.
A very useful and adaptive strategy is to frame the problem as if it were happening to someone else. Ask yourself, “If this were happening to someone I care about, what possibilities would I point out that they’re currently missing?” This will help you distance yourself from the situation. You can also ask someone you trust to challenge your perspective, not just agree with you.
Therefore, the next time you find yourself facing the same problem or conflict, perhaps you don’t need a better hammer, but rather to stop, look up, observe what is in front of you again and ask yourself: what if this isn’t a nail?
