Why cybersecurity training isn’t enough to stop phishing hacks Oct 09, 2025

A recent study of nearly 20,000 University of California, San Diego Health workers found cybersecurity training reduced the likelihood of successful phising attacks by just 2%.

AI "workslop" is hurting coworker dynamics Oct 08, 2025

Show notes

AI slop is pointless content shared online like fake images and videos. A new study in the Harvard Business Review wants us to consider a variant: “workslop,” or AI-generated reports, emails and more that are sloppily crafted.

The authors of the study say 40% of workers they surveyed have encountered workslop. And that's costing time and money.

Marketplace’s Nova Safo spoke with social psychologist and vice president of BetterUp Labs Kate Niederhoffer, who co-authored the study. She said workslop harms interpersonal work relationships, such as when one employee receives an AI written report from another.

Show notes

The number of scams involving job postings and offers nearly tripled between 2020 and 2024, according to the Federal Trade Commission. The change translates to more than $500 million in reported losses.

Marketplace’s Nova Safo spoke with Mark Anthony Dyson, author of the Job Scam Report newsletter, about how to spot scams.

Marketplace’s Nova Safo spoke with Natasha Mascarenhas, reporter at The Information, to learn more about all these stories on this week’s Marketplace Tech Bytes: Week in Review.

Could AI ever be used safely for mental health support? Oct 01, 2025

Show notes

The role of artificial intelligence in mental health care is an unsettled issue. States including Illinois, Utah, and Nevada limit or ban the use of AI for therapy. And researchers say such conversations can sometimes veer off course and even be dangerous.

Colleges turn to video essays to counter AI-written submissions Sep 30, 2025

Colleges and universities are dealing with a growing problem of college admission essays being written by artificial intelligence. Rather than try to figure out which essays are AI-generated, some schools are turning to an alternative approach: Have students submit a video instead.

Can an AI chatbot change your political beliefs? Sep 29, 2025

Show notes

Researchers at several universities tested how successful artificial intelligence can be at political persuasion, and found some AI chatbots were 40-50% more successful than a static message at getting people to change their views. And those views often stayed changed weeks later.

Marketplace’s Nova Safo spoke with David Rand, one of the researchers involved in the study who’s also a professor of information science and marketing management at Cornell University.
