As a break from everything else that's been going on lately, I've been reading/watching a variety of what could be largely lumped as "science communication" blogs/videos. While I've been doing so, I of course have run across the odd "why do science communication?" post. The answers usually boil down to geekery ("because science is so cool and people should know it"), political ("If everyone were more science literate, they would vote X"), or humanitarian ("if people understood [this], they wouldn't be hurt by [that] or taken in by charlatans"). These are by no means bad motives for doing these things. And I utterly agree that science communication is a critical activity in our day and age.
But, why? Why is science so hard to communicate that we need not only institutionalized communication (e.g. science class), but grassroots efforts, from blogs to podcasts to videos to local science festivals? Humans have been communicating stuff to each other for centuries. We have developed a wide variety of methods and tools for convincing people of things. Heck, we have a whole industry dedicated to it (advertising). Why does science communication seem so hard to do sometimes?
First, there is the sheer logistical reality of it. The better you understand a topic, let's say optics since I know that one, the deeper you've gone into it and the more that subject and it's prerequisites have become second nature to you. You now now Maxwell's equations almost instinctually. You have a gut reaction when you see velocities faster than \( 3*10^8 \ . You either stopped asking what was waving or have dug really deep into it, but either way you probably can't explain it in 100 words or less to the average person on the street. On the other hand, the less you know the topic, the easier it is to explain at your level of understanding to someone who doesn't know much or anything, because you remember being in that state.
I have slowly started to realize this as I've been teaching problem solving sessions for the past five semesters. When I started out, I was not remotely confident in the topic. I had taken a few courses beyond the level I was teaching, but I knew I didn't really *know*, in the sense of understanding and internalizing, even basic electromagnetism. My algebra/calculus was shaky because I didn't do it all day, everyday, and hadn't really touched it in 8 months (I took some time off between undergrad and grad school).
So everytime I taught, I had very very detailed notes explaining the calculation to myself, because I knew I couldn't do it unprepared. My students were able to follow my solutions (handwriting permitting) because I wrote everything out, every single step, no "and it can easily be shown that", no "clearly, this equals". It was there. But my analogies to explain the weirdness of electromagnetism were terrible. I mean, really really terrible. Confused, convoluted, mixed. And I didn't have a sense of the background of my students, what they would or would not be familiar with.
Now, I do algebra and calculus for my PhD research. My dining room table, my chalkboard, my whiteboard, my desk, random napkins are full of equations. I sit and do page after page (and redo page after page) of math. I've gotten better at recognizing common algebraic patterns. I no longer have to FOIL simpler multiplications. I do not question the utility of sines and cosines. It's obvious! So my worked out solutions in class have started to skips steps. Bit by bit, I assume a higher level of math literacy from my students. My analogies and metaphors have, generally, become better. I no longer mix metaphors, I stick with one main metaphor throughout a topic, and I don't use analogies to things that my students have no idea what that is. So while my students feel less baffled by my words, I get a dozen of them before and after class asking how we got from point A to point B in an equation.
And this is I think a hurdle science communicators have to face. The best ones are good in their field. They breathe physics, chemistry, biology, what have you. It's a core component of their being and they are excited to share it with you. But it also means that they are far away from the confusion and doubts of their audience. They need to practice that skill of empathy which, at least in pop culture, we famously lack. It's not an easy skill, to put yourself back at that point of confusion and try to talk to that person. It's like trying to teach a small child something that is to you so easy you don't think about it, like tying your shoes. The best thing is to have a non-STEM friend to test out your explanations on, but even they can be a biased sample depending on how frequently you try to explain your work to them.
The second problem, as the many youtube comment sections to these videos attest, is that science bumps up uncomfortably against areas of worldview and identity for people. The world is a big, nasty, confusing place and people build their worldviews and identities in a way that, fundamentally, tries to make them feel safe, even if it is a very weird and convoluted safety. For example, conspiracy theorists, whatever their theory of choice, want to believe that someone is in control. The idea that violence or disease or natural disaster just happen, is intolerable. Far preferable that a malevolent and powerful group somewhere is in charge than we being hostages to fortune.
And this is even harder than empathy for confusion, because it does not require a shoveling on of better explained facts, or more facts. It requires the mindset of a missionary instead of a teacher and it is a very different mindset. Its also a mindset that makes many scientists uncomfortable. Science isn't a religion, it isn't faith, it's fact. Facts exist whether you want them to exist or not. But science is increasingly touching areas of our lives that are not experienced as fully rational, where strong beliefs are preexistent and the science communicators job is no longer to make clear something that was not thought of or not understood, but to modify or replace beliefs. And it is a much longer process.
I feel it is important to note here that science communicators should also be aware of where to stop. There is a fine line between teaching scientific truth and teaching your world view. Most of the time I have seen science communication blow up is where that line is crossed. For example, please, by all means explain the correct mechanisms for evolution and the strength of evidence we have for it. The minute you say "See? You don't need a god to make this work after all" you have lost any ground or good will you may have gained.
I think we could borrow a bit from missionaries, modified to our needs. One of the classic techniques for missionaries is to talk to people, and begin from their starting point. The missionary can then more easily lead in small steps to the point where the next step is faith or not faith. I don't see why would couldn't develop a similar method for science communication where the problem is not information but belief. Again, using evolution as an example. Starting with something close to home (antibiotic resistant infections), moving further afield to elephants losing their tusks as a defense against ivory poaching, to dogs from wolves, making the gradual transition from 'microevolution' to 'macroevolution' to a final understanding that it is all just 'evolution'. But again, changing beliefs is not fast. It requires investment.
So, what is it that I am trying to say? Are we doing science communication badly? Should we stop doing it unless we can be just great? NO. By no means. What I am saying is that we already have a community of science communicators who are really good at what they do. Dr Skyskull has a great blog for weird physics, occasionally cats and horror. Myles Power has a bunch of great videos largely debunking bad science/logic in a fairly respectful manner even if his language is a little coarse to american ears. JimTheEvo has a really cool series on infection, evolution and human history*. My point is that we can be even better. Maybe by focusing our audience, maybe just by being more thoughtful. I think it might be time to move to the next level.
*I know they are all males. The women scientist blogs I read are less explaining and more linking to it things people would know. Powered by Osteons does a great job pointing out where bioanthropology intersects popular culture, for example.
