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! 🙏

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.

By casting doubt on antidepressants and other well-studied drugs, our government health agencies are choosing minimal risk to a fetus over the major risk to the person carrying it

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

We need more of this.

Chris Murphy @chrismurphyct.bsky.social · 2d

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.

We found a troubling emergent behavior in LLM.

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?

"This is based on what I feel" may as well be America's epitaph.

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

Just now at The Atlantic Festival in New York, David Letterman to @jeffreygoldberg.bsky.social: “You can’t go around firing somebody because you’re fearful or trying to suck up to an authoritarian—a criminal—administration in the Oval Office. That’s just not how this works.”

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

Joe Pierre, MD @psychunseen.bsky.social · 23d

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.

A lot of that discussion was about a polarized America butting heads, as if it was an equal fight between two sides. Or musings about the right using violence to overthrow the Biden left.

Now the authoritarian right is in power and I'm not hearing much about anyone putting up an actual fight.

There's been a lot of talk about Civil War in recent years, but there weren't many who had unilateral violent oppression of liberals by a right-wing authoritarian regime on their bingo card.

And yet, that's where we're headed now.

And in retrospect, it's exactly why Trump was elected.

Alan Elrod @aselrod.bsky.social · 25d

“When certain far-right voices vow retribution in response to Kirk’s murder, they’re seizing on it as a bad-faith pretext to wage open warfare on liberals and leftists who are not guilty of any political violence at all.” @gregsargent.bsky.social absolutely nails it

Trump Just Went on Fox and Issued an Unnerving Threat Against Liberals

At a time when right-wing extremists are calling for open season on liberals and the left, the president of the United States just told them: Hey, go for it.

Lara Loomer's tweet clearly illustrates what I explain here about why people support dictators and authoritarianism—they see it as a way to quash their cultural and ideological opposites, whether real, imagined, or contrived.

FALSE is now available at Amazon for the insanely low price of $5.

That's cheaper than it would cost me to mail you a free copy.

No better time than now to pick one up and write a review!
