"Blue Planet Blues"

Written by Paul Sutter on Friday, 20 April 2018. Posted in From The Desk of...The Chief Scientist

What makes it so hard to talk about climate science? Of course the short answer is "politics", but why is it political, and why does that prevent us from speaking clearly about the subject? It's a perfectly respectable field of science, on par with physics, biology, chemistry, and all the rest (and it strongly overlaps with those fields anyway). And yet the subject is, for the most part, only hinted at or spoken about in the most oblique ways.

And I'm not just talking about COSI - science communication efforts across the world seems hamstrung by this topic. Are we afraid of upsetting audiences? Or donors? Or sponsors? Are we worried we might say something so offensive that we won't be allowed to continue our mission?

Probably yes, and probably for a good reason.

Astronomers can debate the nature of, say, dark energy for decades with basically nobody caring or even noticing, because the results of that discussion don't have immediate real-world consequences. It's of only literally academic interest. But our increasing understanding of the nature of the Earth's climate and humanity's impact on it drives major policy decisions, with ramifications totaling billions (trillions?) of dollars and affecting real human lives.

So yeah, it gets messy, real quick.

I think the breakdown in climate discussions occurs because sometimes we go too far. It's one thing to talk about the science: how we know that the Earth is getting warmer due to human activities. And it's totally cool to use scientific reasoning to forecast impacts on climate from decisions that face us now. But is it our place to advocate for certain policy decisions? I honestly don't know - it's an open question.

I do know that when we push a certain choice of what to do about climate change, we enter into the complex, emotional, highly charged world of politics. And when people's politics are threatened, they get defensive - if they don't like the policy, they're going to fight against it. And the first place to strike is at the base: questioning the basic science that led to that policy.

It might be that the climate well is so poisoned by now that honest discussions of the raw science are nearly impossible, and it's best to just stay out altogether. But maybe not. Maybe there's an opportunity to engage audiences with the fascinating, wonderful world of our study of the Earth's climate, and let them come to their own conclusions.

If we want to be known as respected, impartial facilitators of all science, perhaps we could start by being respected, impartial facilitators of all science.

"Fighting Bias"

When it comes to science, perhaps the most dangerous form of bias is simple wishful thinking. Oftentimes the data are extremely hard to come by in the first place, requiring huge investments of time, money, and hardware. After all that effort you probably really, really hope that your hypothesis works out. If it does, you get to publish, speak at conferences, and have a shot of getting your grant renewed. If it doesn't, well, maybe you can come up with a new idea?

So I'm sympathetic to scientists who unconsciously try to make their results look as good as possible. They're working in a broken system, with the number of their papers and the size of their grants determining their fate. But that subtle incentive introduces an ugly bias into the body of scientific research: apparent results that simply aren't there.

It's the job of the rest of the scientific community to a) be aware of that bias, and b) fight against it. You may have heard that some fields of science are facing a "replication crisis", where the majority of results are not holding up to further scrutiny. This is good! It's a sign that the field is self-policing and actively working against the implicit biases that lead to junk research. Imagine a world where we didn't even know these fields were facing a crisis, and the results were simply taken at face value. Is that world better or worse than our current situation?

For example, the CalTech astronomer Mike Brown and his colleagues argue that there is evidence for an additional massive planet in the outermost solar system, but many other astronomers argue against that hypothesis and present their own lines of evidence to counter. And he doesn't blame them - he even admitted during a recent talk that had he seen a competitor publish those same results, he would've scoffed and worked to disprove them.

Fighting bias in science isn't some lofty high-minded virtue. It's a result of natural human grubbiness and our desire to prove our opponents wrong and to demonstrate our own correctness. Progress in science relies on a community of healthy skepticism and open debate - those are the core principles that drive advances in understanding.

"The Dangers of Scientism"

Written by Paul Sutter on Sunday, 08 April 2018. Posted in From The Desk of...The Chief Scientist

It's our mission as science communicators to, well, communicate science. And not just its processes and methods, but also the value and importance of science in modern society. But there's a dangerous line that's very easy to cross when promoting all things science: that science is all the things.

Let's look first at the difference between patriotism and jingoism. It's perfectly fine and acceptable to be patriotic: to love one's nation, its people, its ideals, and to strive to make it better. It's another to turn that love for one's own country into a hatred for others, to believe in its superiority over all the other nations of the Earth, and to use that belief to back aggressive aims.

Scientism is the position that science isn't just a cool way to learn things about the universe, but The One True Way, superior to all other paths of knowledge and understanding. Something along the lines of "If it ain't science, it ain't nothing." That science is capable of answering any possible question (or at the very least, arguing that the only questions worth considering are those that are amenable to the scientific method), and that humanity can safely discard religion, philosophy, and even the arts as relics of the past.

I'm not saying that it's our job to promote anything but science - we are to be clear, strong-voiced advocates for its value. But the people we are speaking to are real humans with real lives with real beliefs. The moment we switch from promoting to attacking, we stop communicating, and we've failed our mission.
