Curiosity in Incident Investigation: The Skill That Prevents Premature Conclusions

  • Jul 30

An incident investigation rarely begins without an early story. Someone missed a warning. A procedure was not followed. A barrier failed. A decision appears difficult to understand.


The first explanation may sound plausible. It may even fit the information available at that moment. That is precisely when curiosity matters most.


Curiosity in incident investigation is not simply an enthusiasm for asking questions. It is the professional discipline of recognising that an explanation can be convincing without yet being complete.


A curious investigator does not automatically reject the first explanation. Nor do they accept it because it appears obvious. They remain alert to what has not yet been understood, what does not fit and what might change the emerging picture.

That ability can determine whether an investigation discovers how an incident developed or merely confirms the story with which it began.



The First Explanation Creates Direction ... and Risk

Investigations often take place under pressure. Leaders want clarity. Operations may need to restart. Employees want to know what happens next. A serious outcome can create a strong desire for a decisive answer.


In that environment, an early explanation provides direction. It reduces uncertainty and creates the sense that progress is being made. It may also narrow the investigation before the evidence has been properly considered.


Suppose an operator did not respond to an alarm. The first explanation might be that the operator was distracted or insufficiently attentive. Once that interpretation takes hold, it can begin shaping everything that follows. Interviews focus on concentration. Training records are reviewed. The operator’s decisions receive increasing attention.

The explanation may ultimately prove relevant.


But the investigation could still overlook whether the alarm was recognisable, reliable or meaningful in the circumstances. It may not explore what else required attention, how similar signals had previously been handled or whether the system clearly communicated the urgency of the situation.


The danger is not that an initial explanation exists. Investigators need provisional ideas to guide their work. The danger is forgetting that the idea is provisional.



Curiosity Creates Space Between Observation and Judgement

A technician uses a method that differs from the written procedure. That is an observation. Describing the technician as careless, complacent or unwilling to comply is an interpretation.


The space between those two statements is where the investigation must do its work.

Curiosity protects that space. It encourages the investigator to ask what the method achieved, whether it was commonly used and how the prescribed approach worked under real operational conditions. It keeps the action open to explanation before attaching a judgement to it.


This does not mean looking for reasons to defend every deviation. Nor does it require the investigator to assume that all behaviour was reasonable. It means recognising the difference between what the evidence shows and what the investigator currently thinks it means.


That distinction can be difficult to maintain. Once an interpretation sounds credible, it begins to feel like a fact. Language then reinforces it. A provisional concern becomes “the cause”, and a possible influence becomes an established finding. Curiosity helps the investigator notice when that shift is happening too early.



Experience Can Strengthen Curiosity ... or Replace It

Experienced investigators recognise patterns. They have seen recurring weaknesses in procedures, supervision, communication and barrier management. They can often identify promising lines of enquiry more quickly than someone who is new to the role.

That experience is valuable.


It can also create a subtle risk. Recognition feels efficient. A situation resembles a previous event, and the investigator believes they know where the explanation is heading. Familiarity can then reduce the urge to explore what is different this time.

Professional curiosity does not require investigators to ignore their experience. It requires them to use experience as a source of questions rather than as a substitute for evidence.


The experienced investigator may think: “This looks like another communication failure.”

Curiosity adds: “What exactly was communicated, understood and expected in this situation?” The difference is small but important. One statement closes the category. The other opens it for investigation.


Expertise becomes most useful when it helps the investigator see more possibilities, not when it makes the answer appear certain too soon.



Contradictions May Be Signs of a Better Explanation

Investigation evidence is rarely perfectly aligned. Witnesses may remember the sequence differently. A written procedure describes one method while employees describe another. Recorded information does not fully support the first account. A manager’s understanding of the task differs from what is observed in practice.

These contradictions can feel inconvenient. They complicate the narrative and slow the movement towards a conclusion.


There is therefore a temptation to resolve them quickly. One witness may be considered unreliable. A difference may be attributed to poor memory. Evidence that does not fit the emerging story may be treated as peripheral.


Curiosity gives contradictions a different value. A difference between accounts may reflect what people could see from their respective positions. A gap between procedure and practice may reveal how work has adapted. An unexpected record may show that the event unfolded differently from how it was initially reported.


Not every contradiction will prove significant. Memories are imperfect, records can be incomplete, and some differences cannot be resolved. But evidence that does not fit deserves attention before it is dismissed. A strong explanation should account for the important evidence, not simply organise the most convenient parts into a coherent story.



Curiosity in Incident Investigation Changes the Quality of an Interview

An investigator’s questions often reveal the conclusion already forming in their mind.

Consider the difference between: “Why did you ignore the warning?”

and: “What did the warning mean to you at that moment?”


The first question contains an interpretation. It assumes that the warning was noticed, understood and consciously disregarded. The second seeks to understand how the situation appeared to the person involved.


Curious interviewing allows an account to develop before the investigator decides what it means. It creates room for information that was not anticipated and makes it easier to understand what the person was trying to achieve, what they expected and what appeared important at the time.


This does not mean that an interview should remain broad or uncritical. Specific issues still need to be tested. Accounts must be compared with other evidence. Difficult questions may need to be asked.


The distinction is in the sequence. Curiosity gathers understanding before challenging the explanation. Premature judgement challenges the person before the situation has been understood.


The quality of the next question then depends not on a prepared list, but on how carefully the investigator listens to the answer. That is a capability developed through practice, feedback and reflection rather than through questions alone.

Curiosity Looks Beyond the Formal Version of Work

Documents can show how work is intended to happen. They do not always show how it actually happens.


A procedure may appear clear when read at a desk but be difficult to use while carrying out the task. A control may be correctly labelled but hard to distinguish from the operator’s usual position. A required check may be achievable under normal conditions yet impractical during an operational disturbance.


Curiosity takes the investigator beyond the formal description of work. It may lead towards the workplace, the equipment and the normal routines surrounding the task. It encourages comparison between what the organisation expects and what people need to do in practice. That comparison can reveal conditions that no longer feel unusual to those involved.


A recurring alarm may have lost its meaning. A temporary workaround may have become standard practice. A weak barrier may routinely depend on individual vigilance. Employees may have learned to manage a problem that the organisation barely recognises.


These conditions are easily missed because they are part of everyday work.

The incident may not have been caused by something entirely new. It may have occurred when familiar adaptations, which had succeeded many times before, no longer produced a safe outcome. Curiosity connects the event to that wider operational reality.



Labels Can Give the Impression of Understanding

Incident reports frequently use terms such as:

  • human error;

  • poor communication;

  • complacency;

  • lack of awareness;

  • inadequate supervision;

  • failure to follow procedure.


Such labels may identify an area that deserves further attention. They rarely explain the incident by themselves.

  • “Poor communication” does not indicate which information was missing, who expected it, how it was communicated, or why the misunderstanding went undetected.

  • “Complacency” may express a judgement about someone’s behaviour, but it does not explain how the situation appeared at the time.

  • “Failure to follow procedure” identifies a difference between expectation and action without explaining how that difference developed.

  • Curiosity resists the comfort of these broad labels.

It asks whether the term adds genuine understanding or merely names what remains unexplained.


This matters because a report can sound complete yet provide little basis for improvement. The reader sees familiar categories but cannot trace how the relevant conditions shaped the event. Strong findings make that relationship visible. They do not rely on a label to perform the explanatory work.



Organisational Pressure Can Reward Premature Certainty

Premature conclusions are not always created by the investigator alone. The surrounding organisation can make curiosity difficult. Leaders may ask for “the cause” before the evidence has been gathered. Early updates may be repeated until they become accepted as fact. Operational decisions may depend on a clear explanation. A person may already have been blamed, removed from a role or publicly associated with the event.


In these circumstances, maintaining an open enquiry can appear indecisive.

The investigator may feel pressure to provide certainty before certainty is justified.

Curiosity then requires professional confidence.


It means being able to distinguish between what is known, what is currently suspected and what still needs to be understood. It also means accepting that a credible explanation may become more complicated before it becomes clearer. This is not an argument for unnecessarily delaying an investigation.


Organisations need timely information, particularly when immediate risk must be managed. But an early operational decision is not the same as a final investigative conclusion. Managing uncertainty responsibly is different from pretending that uncertainty no longer exists.



Curiosity Requires the Courage to Reconsider

Changing an explanation becomes harder as an investigation progresses.

Interviews have been completed. Evidence has been organised. Leaders may already have received an update. A timeline may appear to support the emerging story. New evidence that challenges this view can feel disruptive. The easiest response is to absorb it into the existing explanation or treat it as an exception.


Curiosity creates another possibility: reconsidering whether the explanation still fits.

That does not mean abandoning a sound analysis whenever a new detail appears. It means remaining willing to revise the investigation when important evidence demands it.


Reconsidering a conclusion is not evidence that the earlier work was wasted.

It may show that the investigation is doing what it should: allowing evidence to improve the explanation. The purpose is not to defend the first story. It is to produce the most credible understanding the available evidence can support.



Curiosity Needs Focus to Remain Useful

An investigation cannot pursue every possible question. Time, access, significance, and risk all influence the required depth and scope. An endless enquiry can collect large amounts of information without producing greater understanding.


Curiosity therefore needs focus. The relevant question is not: “What else could we investigate?” It is: “What do we still need to understand before we can explain this incident credibly?” That keeps curiosity connected to purpose.


A new line of enquiry deserves attention when it could materially affect the explanation, the findings or the organisational response. Other interesting questions may need to remain outside the scope. This balance is part of professional judgement.


Curiosity keeps the investigation open. Focus prevents it from becoming directionless.

Developing both requires more than knowledge of an investigation method. It requires practice in deciding when to explore, when to test and when the evidence is strong enough to support a conclusion.



Better Conclusions Begin with Better Investigative Thinking

A methodology can require evidence gathering, interviews, timelines and analysis.

It cannot guarantee curiosity. An investigator can complete every formal step and still reach a narrow conclusion if the first plausible explanation is never genuinely challenged.


Curiosity is what keeps the process alive. It creates space between observation and judgement. It gives contradictions investigative value. It helps the investigator look beyond labels and formal descriptions of work. It makes it possible to change direction when the evidence no longer supports the original story.


The first explanation may ultimately prove correct. But a strong investigation should demonstrate that it survived careful enquiry rather than simply being accepted before other possibilities were considered. That is why curiosity is not merely a useful personality trait. It is an investigative discipline. And it is one of the strongest protections against reaching a convincing conclusion before reaching a well-supported one.
