I think the issue has more to do with the Cassandra effect and the tendencies of some to not consider or want to act on potentially catastrophic situations if they believe it imperils their own more immediate well-being or status.
And, well, sometimes the people making those choices are wrong. Or shortsighted. Or egotistical. Or afraid for their own comfort, power, and privilege.
At the same time, I still don't take the warnings of the flat-earthers particularly seriously, so perhaps not all warnings of potentially catastrophic situations are equally credible. As opposed to how seriously I take the warnings of climate scientists.
I read How To Make Friends And Influence People. Then I threw out all the fluff about genuine connection, and realized that people only actually care that you make them feel like they've been understood. This is the implicit thesis of the book, once you realize that a decades-dead author cannot possibly have a genuine two-way emotional connection with you.
In practice, this tends to mean telling people they're right a lot. Then you imply they have the wonderful, glorious opportunity to become more right. Then you remind them of how right they are. If this sounds exhausting, well, it is. But it also matches the structure of my previous comment.
