What is a scientist to do when they discover a vaccine or cure for something; say fuck it who cares if we change behavior? Are you saying a good vaccine advocate is someone who ignores the underlying science and acts dogmatically?
It just feels like you want to demonize this action of activism for… why? Just because there are lots of bad activists? There are a lot of bad scientists as well, to be honest the view of “good scientist” and “bad activist” feels dogmatic.
To answer your second point, science has a process for disseminating new findings. It's not perfect, but it works. Organizations that scientists work for do pay attention to those sources, discoveries do get patented and productionized. I encourage you to conduct some research: See how many people were talking about mRNA vaccines and gain-of-function research on social media before COVID vs after. The lack of social media coverage didn't affect the science or the scientists, who had spent the past decade conducting research on the subject.
I will maintain that Twitter/X/Bluesky are not part of the scientific process, nor should they be. These platforms do not encourage objective thought or reasoned arguments.
And then that’s just to get money in your specific direction, getting money in your general direction requires more broad activism.
It would be a sampling bias fallacy to draw conclusions based on your lack of observations.
Eg: "mountains, never seen them, they don't exist."
It is funny then for a geologist to be considered an activist when they say the mountains most certainly do exist.
Your first paragraph is unfounded. (Fwiw, The other two I found interesting. )
