Digital tools like virtual therapy and meditation apps have made mental health care more accessible. But they’ve made data about the people using them more accessible too. That’s what Joanne Kim found while conducting research as an undergraduate student at Duke University. Kim identified 11 data broker firms willing and able to sell highly sensitive mental health data to her. Marketplace’s Meghan McCarty Carino spoke with Justin Sherman, a senior fellow at Duke’s Sanford School of Public Policy who helped oversee the study, about how this data ends up on the market.

The artificial intelligence wars are in full swing, with companies like Microsoft and Google battling it out. Now Mozilla, the developer of the Firefox browser, is entering the fray. Last week, the company announced a new startup focused on developing what it calls “trustworthy” and independent AI, built on open-source software that’s free to the public. As with its other products, which are more focused on transparency and privacy, Mozilla aims to distinguish itself in a crowded AI field as a brand committed to the public interest. Marketplace’s Meghan McCarty Carino spoke to Imo Udom, senior vice president of innovation ecosystems at Mozilla, to learn more.

The Federal Trade Commission is tasked with protecting U.S. consumers from unfair business practices, and in recent years it has set its sights on regulating Big Tech. The new Office of Technology will be at the forefront of such efforts. Marketplace’s Meghan McCarty Carino spoke with Stephanie Nguyen, the FTC’s chief technology officer, who will also be leading the new office. She says the office’s work will be critical when you consider how tech has seeped into every corner of the economy.

The COVID-19 pandemic forced a lot of us to stay at home without the chance to socialize in person. But technology allowed us to stay in touch. Social media platforms helped connect us with the outside world — there was Zoom and Houseparty, and remember Clubhouse? But many Americans still struggle with loneliness, even now as life has somewhat returned to normal. Younger Americans are twice as likely to feel lonely than seniors, according to research from Cigna. Marketplace’s Lily Jamali spoke with Kimberly Adams, senior correspondent at Marketplace and host of American Public Media’s series “Call to Mind.” In a recent episode of that show, she explored what role technology plays in people’s lives when they’re struggling with loneliness. And Adams says loneliness is something researchers have been looking into for decades, way before the pandemic.

TikTok’s CEO heads to Congress Thursday to defend the app against concerns it poses a national security threat. Pressure has been building from both the White House and Congress to force the Chinese-owned company to sell TikTok to an American company or face a nationwide ban. And while TikTok has never been in more political hot water, over on the app it’s still all viral pasta recipes, dogs demanding a “cheese tax” and not a whole lot of paranoia about data privacy. Researchers and TikTok creators alike are taking note of the disconnect.
