It shouldn't be shocking that the same political journalists who feel that they shouldn't face consequences for massive ethical and professional lapses find it quaint that anyone wants politicians to face consequences for ethical and professional lapses.

There's a classic joke list of how different programming language handle shooting yourself in the foot.
In the spirit of that, I'm going to make a collection of how the current media landscape would handle Trump shooting himself in the foot.

Having looked through the Genesis Mission launch materials (a US gov program to apply AI in the sciences), this has the feel of Google adding AI to the search. It's being done without understanding whether the people who would purportedly be its users want or would benefit from it.

Journalism is not simply regurgitating facts. It is *certainly* not simply repeating what someone else said -- even if that person is famous. Rather, journalism should offer the reader a service. It should not only share information, but place that information in context.

Regardless of how you feel about the politicization of scientific issues, the environment we're in makes it hard to escape. Scientists certainly didn't choose this fight, but it's happening and they should be prepared to act accordingly.

We had a whole bunch of politicians in advance of the No Kings rally claiming they were going to be "hate America" and "pro-Hamas". Obviously didn't happen. Maybe I missed it, but were any of them asked on camera how they got things so badly wrong?

I'd just like to point out that, when it's suggested that groups like coal miners move to areas with more/better job opportunities, the MAGA crowd has a conniption.

One interesting thing to me about this Politico piece is that there's two phrasings. Most are "Person X declined to comment for this piece." But on occasion, you get "Person X declined to comment on their role in event Y". I can't tell whether that difference is...

Very much this. Science advocates need to recognize that it has become politically advantageous for one party to undercut trust in science, to the extent that they're willing to put their own voters' lives at risk to do so.
You're not rebuilding trust; you're overcoming propaganda.

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

as a reporter, the part of this that i’ve simply never understood is how the next person to ask a question when he does something like this doesn’t simply repeat the question that set him off. it’s not just solidarity with your colleague, it’s an important question that remains worth asking
I’m not going to pretend it’s easy to say something in the moment when you witness the president do this and you’re aboard Air Force One with all the uniformed officers and secret service and fancy wood accents, but this is really an instance where you should. people.com/donald-trump...

The thing that strikes me as odd about Tom Nichols policing the use of the F word is that, as far as I can tell, fascist governance wasn't his area of expertise, and he wrote an entire book about how it's a problem we don't defer to experts anymore.
