Ever wonder "how can someone believe THAT?"

My book "FALSE: How Mistrust, Disinformation, and Motivated Reasoning Make Us Believe Things That Aren't True" (Oxford University Press, 2025) explains why.

Please give it a read, spread the word, and write a review! 🙏

@gregsargent.bsky.social: "From the tariffs, to the government shutdown, to the ACA subsidies expiring—in every conceivable way, [MAGA is] screwing the shit out of their people.

But they're selling [them on] the notion that they’re making Democratic areas suffer."

House Speaker Mike Johnson is afraid of #NOKINGS:

“This Hate America rally [is] coming up October 18. The antifa crowd and the pro-Hamas crowd and the Marxists, they’re all gonna gather on the mall... It's an outrageous gathering for outrageous purposes.”

This is about risk:benefit and it's pretty simple.

Generally speaking, antidepressants are safe in pregnancy.

Untreated major depression often is not, both for mom and baby.

As always, individual results may vary.

Finally, a democratic leader spelling it out and telling it like it is.

We need more of this.

Chris Murphy @chrismurphyct.bsky.social · 6d

We aren't on the verge of an authoritarian takeover. We are in the middle of it.

But I worry people don't see the whole scheme. They just pay attention to each new daily outrage. So I went to the Senate floor to explain Trump's plan.

Here's a 🧵of the speech. It's important.

I think you might appreciate my book then, in which I emphasize mistrust, misinformation, and motivated reasoning as lying at the core of false beliefs, including those related to politics.

Is it not yet another example of hypocrisy in the extreme that Pete Hegseth lectured the military this morning about “fat generals” and returning to the “highest male standard“ while the Commander in Chief’s corpulent physique loomed in the background?

First they came for the immigrants
And I did not speak out
Because I was not an immigrant
Then they came for the transgendered
And I did not speak out
Because I was not transgendered...
...And then they came for me
And there was no one left
To speak out for me

Precisely. In another version, I included the word "murder" in place of "prosecute."

Joe Pierre, MD @psychunseen.bsky.social · 27d

Since Antifa doesn't exist in any structural or organizational way, it seems obvious that designating "it" as a terrorist organization is merely a way to claim that anyone opposing the Trump administration is affiliated and therefore fair game to prosecute under the Patriot Act.

People who claim to stand for "free speech" are often perfectly content when voices they don't like are silenced.
