Opinion — A lot of what gets called ‘doing your own research’ begins with a conclusion

Climate change is exaggerated. Wildfires are caused by bad forest management. Scientists are ignoring natural climate cycles. Governments are using fire seasons to push an agenda.

Often, only once those conclusions are in place, the search to support them begins. There is no shortage of material to find. Search engines can turn up papers, opinion columns, videos and interviews supporting almost any position. Social media algorithms make the process even easier by feeding people more of what they have already stopped to watch or share.

After a few hours, someone can come away with a folder full of links and the feeling that they have investigated the issue thoroughly. There is probably some level of vindication that their instincts were correct.

That process may involve a great deal of reading but it bears little resemblance to actual research.

Research begins with a question that has not already been answered. A researcher may have a hypothesis — and usually does — but the hypothesis has to remain vulnerable to the evidence. The work has to allow for the possibility that the researcher is wrong.

That distinction is significant whenever wildfire and climate change come up, because these conversations often start at the other end. Someone decides climate change cannot be involved and then collects examples of lightning strikes, arson, forest mismanagement or historical fires. Each example may be legitimate but on their own none of them answers the larger question of how a changing climate affects the conditions in which fires start, spread and become difficult to control.

Science is also giving us increasingly clear evidence of the role climate change plays in wildfire. Climate change does not have to strike the match to affect what happens after ignition. Researchers are studying how a warmer climate changes the conditions a fire encounters, how large those effects are, and how they interact with other factors. Higher temperatures and lower humidity dry vegetation and other fuels, while drought and earlier snowmelt can extend the period in which those fuels are available to burn. Natural Resources Canada says warmer and drier conditions are already altering fire weather and lengthening Canada's fire season.

Researchers can also test how much human-caused warming has changed the odds. A 2024 attribution study of Canada's record 2023 wildfire season compared today's climate with simulated climates without the same degree of human influence. It found that human-caused climate change increased the likelihood of both the extraordinary area burned and the length of the fire season across much of Canada. Earlier attribution work on British Columbia's 2017 wildfire season estimated that human-caused climate change increased the area burned by a factor of seven to 11.

That does not eliminate the roles of lightning, human ignition, forest management or decades of fire suppression. Research allows several factors to be true at once and then tries to determine how much each one contributes.

A lightning strike can ignite a wildfire during a period of extreme heat and drought. A person can start a fire in a forest that has become more combustible after prolonged dry conditions. Forest management practices can influence fuel loads while climate influences temperature, moisture and the length of the fire season. Researchers then have to try to separate those effects.

How much did forest management play a role in this fire?

How would that fire have behaved if it had rained more the previous week?

That work is slower and less satisfying than finding an existing article that agrees with us.

Researchers have to decide what they are measuring and why. They have to consider whether their sample is large enough, whether other variables could explain the result and whether the methods they have chosen are capable of answering the question in the first place. They have to account for uncertainty, explain the limits of their findings and submit their work to scrutiny from people who know the field well enough to find weaknesses they may have missed.

Those safeguards exist because researchers are human. They are subject to confirmation bias, professional ambition, assumptions and mistakes in the same way everyone else is. Scientific methods were developed in part to make those weaknesses harder to hide from ourselves and from other people.

That is also why one study rarely settles a complicated question.

Research accumulates as findings are tested against other data and methods. Other researchers may attempt to reproduce a result, examine the same question under different conditions or challenge the assumptions behind the original work. Some results hold up and others do not. Over time, a body of evidence develops, along with areas where the evidence remains uncertain or specialists continue to disagree.

Finding one scientist who disputes the prevailing view does not erase that process. It may point to a legitimate disagreement that deserves attention. It may also represent a minority interpretation that has been tested repeatedly and has failed to persuade most researchers working in the field. Knowing the difference requires more than identifying someone with credentials who happens to agree with us.

The internet has made scientific information more accessible than it has ever been and in many ways, that is a good thing. Anyone with an internet connection can often read studies that once would have been available mainly through universities and specialist libraries. People should read them, question them and look at competing arguments.

Access to information, though, does not automatically provide the background needed to interpret it.

A climate scientist reading a climate paper brings years of training in the literature, the methods and the assumptions behind the work. A fire ecologist reading a wildfire study may immediately recognize a limitation in a model or understand why a particular measurement was chosen. A member of the public can learn those things, but reading the same document does not instantly place both readers on equal footing.

There is a useful question to ask when we are researching something we already have strong feelings about:

What would change my mind?

If the answer is nothing, then the investigation has already reached its conclusion. Every new article becomes another piece of supporting evidence and every conflicting result becomes something to explain away. That is how confirmation works. It can feel rigorous because it involves collecting sources, comparing claims and spending hours reading, but the outcome was protected from the start.

Climate science deserves scrutiny. So does wildfire science, forestry policy and every government decision made in their names. Experts can be wrong, institutions can fail and scientific conclusions can change when better evidence arrives.

The observations of people who live and work closely with the land matter too, including Indigenous communities and people living in northern Canada, and farmers, ranchers and others whose livelihoods depend on noticing shifts in weather, water and growing seasons.

Questioning those things is part of a healthy public debate but here’s the key: the same standard has to apply to our own conclusions.

When thousands of people have spent years studying climate systems, fire behaviour, forests and atmospheric conditions, disagreeing with them carries a burden of its own. A handful of links does not meet that burden simply because the links are persuasive to the person who collected them.

The test of research is not how much material we can gather for our side. It is whether we have seriously examined the possibility that our side may be wrong.
