Combating Misinformation Runs Deeper Than Swatting Away ‘Fake News’
Americans are increasingly concerned about online misinformation, especially in light of recent news that the Justice Department seized 32 domains linked to a Russian influence operation interfering in U.S. politics, including the 2024 presidential election. Policy makers, pundits and the public widely accept that social media users are awash in “fake news,” and that these false claims shape everything from voting to vaccinations.

Memory Loss Isn’t the Only Sign of Dementia
... In a study published last year, researchers found that people with dementia experienced slight drops in extroversion, agreeableness and conscientiousness before they showed any signs of cognitive impairment. Those personality changes accelerated as more dementia symptoms emerged, said Angelina Sutin, a professor of behavioral sciences and social medicine at Florida State University, who led the study. While the research was conducted using a standardized personality test, there are a few changes in everyday behavior that you can watch out for. A decrease in extroversion, for example, may look like a person becoming more withdrawn, or a narrowing of their social circle.

Human Reviewers Can’t Keep Up With Police Bodycam Videos. AI Now Gets the Job
"Who will watch the watchmen?" In the age of police body cameras, the answer may be "artificial intelligence." ... "For us, it's a game changer," says Jennifer Eberhardt, a psychology professor at Stanford whose work on race and crime won her a MacArthur "genius grant." She leads a team of researchers who used AI to help review and analyze videos of nearly 600 traffic stops by Oakland police. "We could look at the first 27 seconds of the stop, the first roughly 45 words that the officer spoke, and we could use this model to predict whether that driver was going to be handcuffed, searched or arrested by the end of the stop," she says.

Instagram to Automatically Put Teens Into Private Accounts With Increased Restrictions and Parental Controls
Teenagers on Instagram will soon be automatically placed in a new type of account with built-in privacy restrictions that give parents more control. ... Social psychologist Jonathan Haidt, author of the “The Anxious Generation,” wrote in a post on X that he's "cautiously optimistic about Meta’s new teen accounts." "It is the biggest and best step forward I have seen from them," he wrote, later adding that "this is just a first step in reforming an ecosystem that badly needs a simpler, more robust way to identify minors and install real age gating, especially for those under 13."
