> Not to mention, with respect to Scientific American in particular, a betrayal of many decades of higher standards, work and reputation.

It's hard to deny science itself is under attack by the same people who try to establish alternative facts and truths based on what's politically convenient to them, even if nothing of that is backed by objective reality. Science will always be a force pushing against such agendas.

How is the best way to serve the higher standards of SciAm? Would it be ignoring the elephant in the room, this new shiny fake reality where vaccines cause autism, the Earth is flat, that scientists have been hiding perpetual motion machines from the public? Or would it be to risk being labeled "biased" or "political" and actively label and fight against these anti-science movements?

Science is politics. It is the strong belief that there is one single objective reality, that anyone with the proper tools can observe and verify, and that going against these cornerstones for political expediency is wrong and, ultimately, against the interests of our species.

Science can touch on politics, but that doesn’t mean science is coextensive with politics. You selected examples where science bears on politics, but Helmuth’s fixation wasn’t on how many people believe vaccines cause autism. As demonstrated by her closing screed, it was about non-falsifiable moral assertions (“sexism,” “racism,” and the “moral arc of the universe”).

Indeed, the point of the Reason article is that if scientists want to have credibility on questions where their expertise applies, they should avoid opining in their official capacity on political questions where their expertise doesn’t apply.

Science has much to say about politically important issues like climate change and vaccines! But people will blow off those assertions if scientists lend the imprimatur of their authority to advance social causes, for example by opining that it’s “racist” to vote to deport illegal immigrants.
