If we want to use scientific thinking to solve problems, we need people to appreciate evidence and heed expert advice.

But the Australian suspicion of authority extends to experts, and this public cynicism can be manipulated to shift the tone and direction of debates. We have seen this happen in arguments about climate change.
This goes beyond the tall poppy syndrome. Disregard for experts who have spent years studying critical issues is a dangerous default position. The ability of our society to make decisions in the public interest is handicapped when evidence and thoughtfully presented arguments are ignored.
So why is science not used more effectively to address critical questions? We think there are several contributing factors including the rise of Google experts and the limited skills set of scientists themselves. We think we need non-scientists to help us communicate with and serve the public better.
At a public meeting recently, when a well-informed and feisty elderly participant asked a question that referred to some research, a senior public servant replied: “Oh, everyone has a scientific study to justify their position, there is no end to the studies you could cite, I am sure, to support your point of view.”
This is a cynical statement, where there are no absolute truths and everyone’s opinion must be treated as equally valid. In this intellectual framework, the findings of science can be easily dismissed as one of many conflicting views of reality.
Such a viewpoint is dangerous from our point of view.
When scientists disagree with one another, as they must to ensure progress in their field, it is easy to argue that it is not possible to distinguish between conflicting hypotheses. But scientists always agree that critical thinking done well eventually leads to a better understanding and superior solutions. All opinions are not equal.
If you are flying in an airplane at 30,000 feet, you will not be content with just any scientific study about whether the wing will stay on the plane. Most people will want to put their trust in the calculations of an expert aeronautical engineer who understands the physics of stresses on the wing.
So why do we not want to trust experts in bushfire management, or climate change? Because most people are happier with experts whose conclusions fit their own ideas.
This encourages people to express their opinions, and the internet allows those opinions to get a wide viewing. This makes for interesting times, but not always effective solutions.
Google experts
The internet is filled with information and ideas. Everyone can quickly find “answers”, and this means that everyone is an “expert“.
But using Google to find the answer to Trivial Pursuit questions is not the same as researching a complex question. Experts do have skills and one of those is the ability to use high quality sources, up to date theoretical frameworks, and critical thinking based on their experience in a particular field. This is why an expert’s answers are going to be more accurate and more nuanced than a novice.
For example, people who use Dr Google to diagnose their symptoms before visiting an actual doctor, sometimes ask to be tested for diseases they do not have, or waste time seeking a second opinion because they are convinced that their “research” has led them to a correct diagnosis. If it were really that easy, would doctors have to spend all those years in medical school?
There is another problem called the Dunning-Kruger effect, which states that “people who lack the knowledge or wisdom to perform well are often unaware of this fact”.
In other words, people who think all answers can be found on Google are likely to be unaware of the effort involved in solving complex problems, or why years of specialist training might help.
This is almost more dangerous than complete ignorance, because unlike Donald Rumsfeld, they don’t even know what they don’t know.
Easy access to huge volumes of confusing information sits very comfortably in a post-modern world. Unfortunately, the outcome is that most people are reluctant to do the intellectual hard work of sifting through competing hypotheses. So how are we to engage in robust scientific debates in such a public arena?
Science is not enough
It has been said many times that scientists need to communicate their research more broadly. The challenges are well known — peer reviewed scientific publications are necessary for our careers and time spent engaging with the public is time away from the field, our computers and laboratory benches.
Nevertheless, if we hope to influence government policy we cannot assume that the implications of our research will be understood by those who most need to know what we are doing.
Reaching out to busy bureaucrats and politicians is not something that comes naturally to scientists. To turn science into policy we need a diverse team of people with different but complementary skills who share a commitment to the task.
Skills that are not commonly found in scientists may be found in political scientists, lawyers, sociologists, public relations companies, the arts community and the media.
Forming relationships with people who can translate our findings into something that cannot be ignored may be critical to success.
Consider what we are up against, lobby groups with deep pockets have come up with brilliant assaults on the thoughtful management of our environment.
“Cutting Green Tape” or “No fuels, no fire” — these clever bits of spin threaten decades of rigorous research and policy development. This is not a failure of science, but a triumph of imagination. We have been dramatically out-manoeuvred, shown to be amateurs, in the world of presenting competing ideas.
At a recent fire forum we learned that current policy is: “Based on science, but driven by values.” This means that despite the best evidence, the values of our current society will decide when to act. This introduces another definition of truth seeking, based on who made the best argument in a political or legal process.
Science is meant to be done dispassionately and objectively, so scientists are not well equipped to participate in debates about values. This is the realm of ethicists, philosophers, artists and theologians.
But if we are passionate about applying the lessons learned from our research, we will need marketers, lobbyists, communication experts, accountants and economists. A multi-disciplinary team is required to convince society to change.
Perhaps the people with these complementary skills will be able to help break down the anti-intellectualism we face, for the benefit of all.

That’s a good article. Here are a few challenges to the suggestions in the article that make this a fool’s errand,
– confirmation bias
– faith
– media & other vested interests
– poor studies vs good studies
– personal bias
Think of a few examples,
– smokers ignoring health warnings
– any bible is littered with provable fallacies and mistakes
– vitamins. There are constantly differing scientific conclusions
The chances of changing these things is next-to-zero. I have come to the conclusion that many people are not interested in the truth, or only want to hear selected truths.
If you can convince people that intangible miracles didn’t happen ~2000 years ago, just like they don’t happen today, then you’ve got a chance of getting people to accept science. The chance of this happening? Nil.
I don’t ‘disbelieve’ the smoking health warnings, i just don’t care. If there were health warnings on a pack of bacon, would that stop you eating it? What about pollution caused by cars, did you stop driving? When health warnings start to appear on alcohol, will the world stop drinking?
I understand your point, but you’re mixing in a range of risk/reward profiles together (although those profiles will of course vary from person to person).
Specifically using fairly extreme cases: smoking vs driving. Smoking has a fairly small profile of positives and fairly significant negatives (in my opinion, of course:I miss smoking, but the negative effects well outweigh the positives I get from it). In contrast, driving has huge benefits of convenience, and the negative effects are distant and distributed (i.e. my driving has a pretty small effect by itself, and very small negative effects on me).
I offer this person (n7of9) as evidence that tobacco is too addictive (in combination with its other damaging effects) to further tolerate in civilized society.
This poor person is so addicted that it has removed their ability to internalize the concept that tobacco use will most likely lead to their premature death in horrible pain, having experienced a life of poor health and poor finances.
Such victims will typically claim a ‘freedom of action’ defense, which is sadly ironic because they have surrendered their freedom of action to a wide-range psychostimulant. Part of society’s job is to protect victims, particularly when a drug has so much control that the victim is no longer a free agent.
I’m paraphrasing a relevant quote here, but there’s also the fact that it’s difficult to change the mind/opinion/beliefs of someone whose financial, social or personal security depends on their mind not being changed.
This applies to a wide gamut of situations: from financial to politics, health to theism.
For some, it can be too hard — even dangerous — to listen to experts and potentially have their beliefs challenged or altered.
In these cases, it takes a brave person to face reality, ask questions, and accept answers based on demonstrable, repeatable evidence or the weight of credible consensus.
In my work, I am introducing new technology for academic use.
The change management of scientists is particularly challenging. They are reluctant to look at evidence obtained through research about the status quo vs potential change. They have adopted hypotheses (in the absence of evidence) that do not fit the evidence. Most are reluctant to give up these hypotheses.
Doesn’t this show that this issue arises from human nature and instinctive behaviours, rather than that scientists (always) think differently to other people?
You work in science;
Yet you think that your unsupported, uncontrolled anecdote ‘shows’ something? O_o
I disbelieve.
Who are the ‘real’ experts in science? Given that in most scientific fields there are different and often opposing theories about a given subject. Each scientific camp has its proponents and detractors, all of whom will cite various studies and research to support their arguments.
This confirms my view that in many areas the answer is not absolute – there is no 100% right or 100% wrong answer, there are degrees of truth instead. If even one variable is missed out, or given the wrong consideration, the results can – and often are, skewed. We see this time and time again in areas like health where often there are so many exceptions to the ‘rule’ that the rule is no longer considered valid – and so the prevailing beliefs, based on supposedly solid scientific research, are overturned.
Then there is the highly contentious issue of independence of research. More and more research these days is funded by organisations with vested interests, and the funding is understood to be conditional on the results pointing a certain way, even if not explicitly stated. This means a lot of research cannot be trusted, which further undermines the validity of the so-called expert opinion. We see large corporations actively pushing either outdated or disproven science in the interests of profit. We see these same organisations preventing people from discovering the truth about their products. And yet, they use so-called experts to argue their version of the science.
Why should I listen to a scientist who is financially dependent on a commercial organisation for his livelihood or his professional opportunities, who claims to be independent and unbiased?
1: There are NOT degrees of truth. Reality defines truth, and is singular.
2: Science improved an earlier model model, and all you saw was an opportunity to criticize the scientific method? Your perception is broken, look again; This is science at its best, self-correcting in its ongoing search for accurate models of reality.
3: ‘Why should I listen’ to someone biased? Because there’s supposed to be some mental processing happening between hearing something, and believing it. If you don’t even look at the research outcomes your assessment will (by definition) be incompetent.
