🔥 Featured story

This week marks the 25th anniversary of the terrorist attacks on Sept. 11, 2001.

Even a quarter century later, the vast majority of Americans who were age 10 or older at the time (93%) say they remember exactly where they were or what they were doing the moment they heard the news about the attacks, according to a recent Pew Research Center survey.

In 2016, about three-quarters of U.S. adults (76%) named 9/11 as one of the top 10 historic events that occurred in their lifetime that had the greatest impact on the country – a far higher share than named any other event.

📅 Looking ahead

An emerging tool known as Arbiter seeks to use artificial intelligence to analyze social media trends and help journalists identify false or misleading narratives. The nonprofit behind the tool is independent from social media companies and has begun to partner with news organizations around the world.

Although trust in information from news organizations has declined in recent years, Americans have consistently expressed even lower levels of trust in information from social media sites. In 2025, 37% of U.S. adults said they had at least some trust in the information they get from social media.

In a 2024 Center survey, we found that most people who get news on X (formerly Twitter), Facebook, Instagram and TikTok said they at least sometimes see news on these sites that seems inaccurate. Another 2024 survey asked people who get news from social media what they dislike the most about it. A lack of accuracy was the most common answer by far.

📊 Chart of the week

Americans overwhelmingly say it’s crucial for people to stay informed on various topics, according to a March survey. But far fewer say they’re highly informed about these topics themselves.

For example, large majorities of U.S. adults say it is extremely or very important for individual Americans to stay informed about the healthcare system (82%), immigration and citizenship policies (76%), and economic and tax policies (75%). But well below half say they are extremely or very informed about these topics.
