Donald Trump is known for his hasty (and frequent) posts on social media.

He regularly has midnight meltdowns on Truth Social, has shared back-to-back posts of AI nonsense on the platform, and threatened people he’s unhappy with in long-winded messages, too.

But in recent months, select posts have concluded with an oddly formal phrase: “Thank you for your attention to this matter.”

“It’s really different than how he typically posts,” said Claire Robertson, an assistant professor of psychology who focuses on political polarization and extremism at Colby College in Maine.

Robertson added that Trump usually uses morally and emotionally loaded words in his posts (such as “hoax” and “corrupt”), which capture attention quickly. “He’s still using a lot of the kind of moral-emotional language that we know attracts attention,” Robertson said of Trump’s social posts as a whole.
