A task that used to run smoothly suddenly starts going wrong at work. One person blames a new process, another suspects a faulty tool, and a third thinks communication has broken down. All three explanations may sound convincing at first. But if you act on the first one, you may end up fixing something that was never broken.
Unclear situations call for two distinct skills: coming up with several possible causes and then working out which ones are supported by evidence. The first opens up possibilities; the second helps narrow them down. This approach is useful for technical problems, workplace misunderstandings, and everyday decisions when information is limited.
Your first idea is a hypothesis, not a conclusion
When something unusual happens, we can quickly form an explanation based on familiar experiences, expectations, or a striking detail. If an error appears soon after a new system is introduced, it seems natural to connect the change with the error. But the fact that one event followed another does not, by itself, show that the change caused it.
Fast and slow thinking are useful terms for two ways of processing a situation. Fast thinking can produce an immediate impression; more deliberate checking helps examine assumptions and consequences. These are not fixed types of people. Even an experienced person can react automatically, and a highly creative person can still work methodically.
Divergent and convergent thinking also complement each other. Divergent thinking involves exploring several possibilities, while convergent thinking means assessing them against the evidence and the conditions at hand. These are not exact synonyms for fast and slow thinking: you can come up with unusual ideas slowly, and sometimes recognise a suitable solution very quickly.
Separate what you observe from what you infer
Start by describing the situation without assigning a cause. Instead of “The new system broke the orders,” you might say, “The number of incomplete orders increased after the system changed.” The first statement already identifies a culprit. The second describes something you can investigate. It may seem like a small distinction, but it shapes the questions you ask.
It helps to separate three layers that are easily mixed together in everyday thinking:
- Observation: what you actually saw, heard, or measured, and when it happened.
- Interpretation: the cause you think the observation might point to.
- Response: what you want to do because you believe that interpretation.
For example, “My colleague did not reply to my message today” is an observation. “They are ignoring me because they disagree” is an interpretation. “I will stop involving them in decisions” is a response. An important check is missing between the first and third statements. Your colleague may be busy, may have missed the message, or may not know what you need from them.
Check whether your information is representative, too. One unpleasant phone call does not show that all customers are dissatisfied. One failed attempt does not mean a solution will never work. At the same time, one success does not prove that it will work reliably in every circumstance.
Come up with three different explanations
Once you have described what happened, try to come up with at least three explanations. This is not a contest in originality. The point is to stop your first idea from automatically crowding out the others. Two versions of nearly the same idea do not count as separate possibilities. You need explanations that would lead you to check different things.
If the number of orders has fallen, three possibilities might be that customers cannot find important information, the form presents a technical barrier, or the sources of website traffic have changed and are bringing in people with different interests. Each explanation suggests a different check. The first calls for reviewing the content, the second for testing the ordering process, and the third for looking at where visitors come from.
Another useful question is: “What might someone suggest if they knew nothing about this situation?” It can help you move beyond looking for a cause only where a similar problem has occurred before. You can also consider the opposite assumption: what if the tool is working properly and the problem lies in an incorrect expectation?
Not all ideas are equally likely. Extreme, fantastical, or technically impossible explanations may be useful as a creative exercise, but they should be separated from feasible possibilities when making a real decision. Imagination can help you build a list; it cannot prove that the list is right.
Choose a check that can distinguish between explanations
A weak check is one where you treat the result as confirmation of your idea no matter what happens. A stronger check starts with a question: if this cause is correct, what specifically should we find? And what would count as evidence against it?
A short table can help. These options relate to a hypothetical situation in which completed applications fall after an online form is changed:
| Possible explanation | What would support it | A simple check |
|---|---|---|
| The form has a technical fault | People get stuck at the same step | Try submitting the form on different devices |
| The questions are unclear | People hesitate at a particular field | Ask a few users to explain how they understand it |
| A different group of visitors is arriving | The mix of traffic sources has changed | Compare traffic sources before and after the change |
None of these checks necessarily provides a definitive answer on its own. Testing on one device will not uncover every technical fault, and speaking to a few users will not tell you what everyone thinks. The goal is to reduce uncertainty at a reasonable cost, not to pretend you can achieve complete certainty.
Before testing, decide what would make you change your mind. If the form works but users do not understand the instructions, there is little point continuing to defend your original suspicion just because you have already invested time in it.
Check what people mean, not what they intend
Unclear situations involving other people can be especially sensitive because you usually have no direct evidence of their intentions. A brief reply might signal disagreement, time pressure, a different communication style, or simply an attempt to be concise. If you settle on one negative interpretation, you may create a conflict that did not previously exist.
Instead of asking, “Why are you ignoring me?”, try: “I sent the proposal on Tuesday and haven’t heard back yet. Do you need more time, or should I add anything?” This statement connects an observation with a question without assigning a motive. It also leaves room for an answer that may disprove your initial assumption.
Checking your interpretation does not mean endlessly excusing repeated inappropriate behaviour. If agreements are repeatedly ignored, focus on specific actions, their consequences, and the boundaries for working together in the future. You do not need to know exactly what someone intends in order to ask for reliable communication.
When to act immediately and when to hold off
Not every situation allows for a lengthy investigation. If there is an immediate risk of harm, a proportionate safety measure matters more than identifying the cause in detail. If there is water on the floor, prevent someone from slipping first; investigate the leak afterwards. If you suspect a serious technical fault or a health risk, follow safety procedures and seek professional help.
In less urgent situations, consider the consequences of being wrong. You can try a small, easily reversible change sooner. A decision affecting many people, requiring a large budget, or difficult to undo calls for more thorough checking.
Before acting, ask yourself three questions:
- What happens if I am wrong? Distinguish inconvenience from serious harm.
- Can I reverse the decision? Seek stronger evidence before taking irreversible steps.
- What will further checking cost me? Sometimes a short conversation, a test, or a check of one piece of information is enough.
Slower thinking is not automatically better. If you keep revisiting the same questions without getting new information, more analysis may not help. Set a time to decide using what is available, and note which assumptions remain uncertain.
Three mistakes that undermine good checking
You look only for confirmation. You select only the information that supports your preferred explanation. Deliberately identify one observable result that would make you change your mind. If there is no such result, you may be protecting an explanation rather than testing it.
You mistake more ideas for progress. Ten new possible causes are not useful if none leads to a meaningful check. After a short period of generating possibilities, choose the ones that matter most to the decision and for which you can obtain information.
You treat one test as conclusive proof. Even a good check can be affected by chance, an unrepresentative sample, or hidden circumstances. For important decisions, compare multiple sources and record what you still do not know.
A short exercise for your next unclear problem
When you next face a situation with no obvious cause, write it down on one sheet of paper. Instead of asking the general question “Why did this happen?”, use a more precise process:
- Describe the situation in one sentence: include only what can be observed.
- List three different explanations: make sure at least one is unrelated to your first suspicion.
- Ask one question that distinguishes between them: what would you observe if one explanation were right and another were not?
- Choose the smallest safe check: take a step that provides new information without unnecessary risk.
- Decide with an appropriate level of confidence: note what you will do for now and what finding would make you change course.
The aim is not to question every small detail. It is to notice when you are tempted to act on a story you have not yet confirmed. If you can use that moment to consider other possibilities and honestly check one of them, your decision will rest on firmer ground than a first impression alone.
