Again, I didn't say that it was necessarily the responsibility of scientists and it definitely shouldn't be their responsibility alone. Science communication should definitely be many people's full time job. But also, yes, I do think scientists should evangelize for themselves too. Do interviews, spread the word. It isn't an either-or situation. Subject matter experts often talk to the media about the work they do. Why shouldn't they? And first person knowledge and expertise is always a better source than some journalistic summary.
Even now, neither of us have run a Google or DuckDuckGo search to try to find it - it's more fun to talk than to listen 🤪. As monkeys, we run on hormones rather than logic, and it's easier to feel superior to everyone else than to actually put in effort to better ourselves.
We HAVE heard about it. The point is that the general public, your friends and family, your neighbors, your working class community, has not. It's not even a little bit about feeling superior. It's that this could 100% be common knowledge.
Just because someone said it and it's on the internet for you to find if you go searching hard enough and dig past the bullshit propaganda like this post, that doesn't mean that the communication is done. If my mom hasn't heard about it, you didn't get the message out wide enough. It is not common enough knowledge until the average person is not susceptible to bullshit posts like Matt Walsh's because they aren't void of any knowledge on the subject.
Putting the onus on individuals in the public to seek out and find the answers is exactly how you get where we are now. Where a small subset of people know the answers and frustratingly have to fight back against incredibly effective misinformation campaigns like this. If we can put the problem in everyone's face making the "Ozone Layer" and "Climate Change" common layman's terms, then we can do the same with the wins against those problems.
