You could be visiting a poor doctor because AI is filling the web with fake online reviews

Real patients rarely share detailed medical stories publicly, and fake reviews are exploiting exactly that silence.

If you’ve ever picked a doctor based on online reviews, a new study from Simon Fraser University has some bad news for you.

Apparently, fake clinician reviews generated without using AI read more believable than genuine ones.

So what exactly did this study find?

Researchers reviewed 35,000 physician and dentist reviews collected in India (between 2015 and 2017), including doctors with specialties ranging from family medicine to dermatology. Within that sample, as many as 8,313 reviews were fake. In other words, nearly one in every four reviews wasn’t drafted by an actual patient.

It was either the healthcare providers or the clinic staff curating them. A closer look at a smaller sample of 5,000 reviews revealed the real problem. The fake reviews ran longer than the genuine ones, as they included far more details about symptoms, diagnoses, medications, and treatment.

They also scored higher on trustworthiness and got more upvotes than the real ones. Lead author Aishwarya Deep Shukla explains that real patients rarely want to narrate their own medical history or diagnosis details on a public platform. Fake reviews, by contrast, lack this hesitation.

What can you actually do about it?

While the bad practice didn’t involve generative AI when the data was collected, easy access to chatbots in 2026 is making the situation worse. The same tools that help genuine patients write authentic reviews are also helping bad actors generate them at scale.

The fixes devised by Shukla are simple. Tying reviews to confirmed appointments, offering authenticated-but-anonymous review options, and pushing platforms toward stronger moderation could help curb the spread of fake or AI-generated reviews.

For anyone searching for a new provider right now, here are a few habits that could help. First, try to read as many reviews as possible without focusing on one story. If most of them are of the exact same length and contain the same phrasing or structure, they’re probably not genuine, unless the provider asks their patients to share reviews in a specific format.

Shukla also recommends staying skeptical of reviews that automatically share unusually personal medical details, and not writing off a provider with few or no reviews, since most satisfied patients never bother leaving one. Finally, you should weigh reviews alongside credentials, referrals, and your own direct impressions. Talking to someone who has already been to the facility could also help.

This touchscreen is made from thread, and scientists want to put it in your clothes

The washable, breathable textile display can run simple apps, play videos, and even measure body temperature.

Forget smartwatches. Scientists have developed a touchscreen that can be woven directly into clothing, letting users interact with digital content without carrying a rigid display. Researchers at the National University of Singapore (NUS) have integrated 54 specialised fibres into a sleeve to create what they describe as the world's first touchscreen built into a garment. Published in Nature, the research could open the door to clothing that does more than just look good. Your next smart outfit might actually be smart enough to show what's happening on your phone.

Scientists have figured out how to send smells over the internet, and coffee is just the beginning

The AI-powered Scentronic system can detect, transmit, and recreate five familiar aromas, bringing digital smell a step closer to reality.

Imagine smelling freshly brewed coffee through a video call or getting a whiff of perfume before buying it online. Scientists are bringing that idea closer to reality with Scentronic, an AI-powered system that can detect smells, transmit scent data over the internet, and recreate aromas remotely. Developed by researchers from Ohio State University and Zhejiang Laboratory in China, the research, published in Science Advances, explores how digital scent transmission could add an entirely new dimension to online communication. Your next shopping session might literally come with a sniff test.

Mori might be the cutest AI companion robot yet, and it reacts to you like a pet

The Pokémon-like companion can blink, dance, act shy, and respond to what is happening around it.

OKA Mori The Nature Companion AI Home Robot

With AI progressing so fast, it's only a matter of time before we start getting AI companions like the ones we used to see in movies like R2-D2, Wall-E, or Baymax. Now, Singapore-based OKA Technology has unveiled Mori, a cute little AI companion that looks less like a conventional home robot and more like someone turned the Pokémon Foongus into a table lamp.

Mori isn't meant to clean your house or control your smart home, but to serve as what OKA calls a "Nature Companion." It uses subtle movements, warm lighting, nature-inspired sounds, and small reactions to make its presence around the house feel calming rather than distracting. Mori can sit quietly while you read, sway along to music, welcome you when you enter a room, or encourage you to slow down for a moment without requiring a screen or a conversation.
