You have zero privacy … Get over it,” Scott McNealy, then CEO of Sun Microsystems, declared in 1999.

What might have sounded like a bold claim at the turn of the millennium has turned into a self-fulfilling prophecy in today’s era of big data and artificial intelligence.

Computer algorithms – step-by-step instructions – can connect the digital breadcrumbs of your existence, including Google searches, browsing histories, social media posts, credit card records and GPS locations to paint an astonishingly accurate picture of your preferences, routines and inner mental life.

These profiles often describe people better than their closest friends and family might. Yours may even tell you something you don’t know about yourself.

And as McNealy said nearly three decades ago, many people seem to have given up on the idea of ever reclaiming their privacy. When was the last time you carefully read the terms and conditions of the products you’re using?

Why do so many people do so little to protect their privacy online? I’m a computational social scientist with a background in psychology and computer science and author of “Mindmasters: The Data-Driven Science of Predicting and Changing Human Behavior.”

In talking to my students as a business professor at Columbia University and giving public talks around the world over the past decade, I have come to realize that people often substitute the question of whether they care about their privacy with two simpler and misleading ones: Is sharing my data worth it? And am I worried about my data being out there?

These questions act as mental shortcuts. They seem reasonable, but can mask your true feelings and lead you to decisions that don’t serve your long-term interests.

The ‘it’s worth it’ fallacy

When I ask people whether they care about their online privacy, they often respond by listing the benefits they get from sharing their personal data: Google Maps navigation, Netflix recommendations, Uber rides.

These are fantastic perks, no doubt. But that’s answering a different question: Is sharing my personal data worth it?

Swapping these questions seems like a reasonable approach on the surface. People often assess value by how much it would hurt to give something up. For instance, I know that drinking five cups of coffee a day might not be great for my health, but I enjoy it too much to stop. Similarly, sharing personal data brings benefits you may be unwilling to give up.

But this substitution is problematic.

First, the upside of sharing data is typically obvious and immediate: If I share my GPS location, Google maps can tell me how to get from A to B. But the downside of sharing data is often far more nebulous and abstract. My GPS location, for example, can also reveal to anyone who collects or buys the data whether I might be at risk of depression. With the carrot in plain sight, and the stick hidden away, that’s hardly a fair battle.

Second, people’s attention naturally gravitates toward the few instances where data sharing benefits them. But those instances are the exception, not the rule. Much of your data is collected and used without any direct benefit to you at all.

Finally, even if the benefits were to outweigh the risks in a particular instance, that doesn’t mean you don’t care about privacy. Ideally, wouldn’t you prefer to enjoy these services while also maintaining a high level of privacy?

The ‘I have nothing to hide’ fallacy

A second common response is I don’t care because I have nothing to hide. This idea has been carefully nurtured by Big Tech: If you’re uncomfortable sharing your data, something must be wrong with you.

But that’s not true. Privacy isn’t about covering wrongdoing. It’s about maintaining control over your personal information and deciding how it is used.

You might not be worried about your data today, but that sense of safety can be fragile. Take history: In 1933, Germany was a democracy. In 1934, it wasn’t. Personal data, such as religious affiliation, included in the census, played a major role in enabling persecution during the Holocaust. Now imagine such regimes having access to today’s digital footprints.

That scenario may feel distant, but the principle is not. The 2022 overturning of Roe v. Wade – which had guaranteed a constitutional right to abortion for five decades – made privacy suddenly relevant for millions of American women, whose search histories, app usage and location data could suddenly be used against them.

No matter how safe you feel today, you cannot predict how your data will be used tomorrow.

Asking the right questions isn’t enough

Understanding the true value of privacy, and realizing that you care about protecting it more than you might have thought, is a necessary precursor to action. But personal motivation isn’t enough.

Managing your personal data in today’s world is time-consuming. It’s too much for even a very efficient and diligent person to read and decipher the legalese of all the terms and conditions they sign off on.

For the intention-action gap to close, the burden to protect privacy needs to shift away from individuals and toward systemic solutions. That means designing policies and technologies where the safe choice is the easy one, and where maintaining privacy doesn’t automatically mean giving up on convenience and better service. Privacy-by-design standards could include more restrictive default settings. Connected computers could process information without exchanging raw data by using decentralized networks such as federated learning. New forms of collective data governance such as data trusts could also help serve that function.

Because data is permanent but leadership is not, I believe that the real solution isn’t to expect people to outmaneuver the system that exploits them but to build one that is worthy of their trust.

  • A bonobo’s make-believe tea party has scientists rethinking whether imagination belongs only to humans

    Childhood activities like playing house, superheroes and villains, the floor is lava, and the classic tea party all involve imagination. We create stories and worlds with rules and roles to play.

    Humans want to believe that our creativity and art make us unique. But a bonobo named Kanzi was part of research that has scientists wondering how different we really are. In three evolving experiments, Kanzi correctly identified pretend objects, demonstrating that he could understand and engage in make-believe situations.

    Kanzi has a make-believe tea party

    Researchers developed a simple setup using cups, a pitcher, and actions that began as real pouring and gradually shifted into pretend play. The first experiment used real liquids. The second had a combination of real and pretend liquids. The final scenario had no real liquids and relied entirely on imagination.

    The scientists used gestures and make-believe to see if Kanzi would react differently depending on what he was being shown. He didn’t react the same way in each setup. His responses showed he was paying attention to more than just the objects, but also to the way the situation was presented.

    Animals engaging in fantasy

    The experiment revealed that non-human animals can understand and follow along with imaginary situations.

    “[It] shows that animals are capable of understanding pretence in a controlled experimental setting, which hadn’t been done before,” Dr. Amalia Bastos, first author of the research from the University of St Andrews, told The Guardian.

    Scientists involved in the research are careful about how they describe it. They don’t treat it as proof that bonobos imagine things the same way humans do. Instead, they suggest that animals are capable of responding to situations where meaning is implied rather than directly shown.

    Why scientists care about pretend play

    Albert Einstein, one of the greatest scientific minds in history, is often credited with the idea that logic gets you from A to B, but imagination can take you everywhere. This study suggests that the more we learn about animals, the more it seems the difference between us may not be as great as we once thought.

    Developmental research credits early social and cognitive growth in human children to imagining situations that aren’t physically present. A 2024 meta-analysis found that make-believe is not just entertainment but also directly linked to social understanding and real-world interpretation.

    Researchers now describe animal play as more flexible than once believed. A 2025 study of ravens revealed that play included the manipulation of sticks, stones, and other items, suggesting social awareness and responsiveness to context rather than simple instinctive behavior.

    Play and imagination may be versatile behaviors no longer seen as uniquely human traits. A broader cognitive toolkit shared across multiple species suggests the gap between humans and animals may be smaller than it once seemed. Things we’ve long believed to be uniquely human may instead exist along a spectrum of abilities expressed in different ways.

  • As climate change causes flooding in London, experts found an effective, low-cost solution: beavers
    Photo credit: CanvaBeavers are solving several climate issues.

    West London’s Greenford Tube station had an ongoing problem. Due to climate change, the station would often flood during heavy rains. The rain would cause a nearby creek to overflow, flooding the ticket office and beyond. But in 2023, officials tried a natural method to help offset the flooding. All they had to do was bring back a vanished species to the area: beavers.

    A family of five beavers was released through the Ealing Beaver Project to act as “nature’s engineers” and help solve London’s flooding problem. Within weeks, the beavers built a dam in the creek, causing it to pool into a pond. Along with that, the beavers created new pathways and tributaries that further diverted water from the main creek. The small group of beavers not only built seven dams in their first year but also expanded biodiversity near populated areas.

    The combination of rerouting water and felling trees has brought new animals and species into the area. Some of the new additions inhabiting the creek are freshwater shrimp, two types of bats, a rare brownstreak butterfly species, and eight new species of birds. A whole new nature preserve is forming remarkably close to urban areas. In fact, the beavers are working just 100 meters behind a McDonald’s.

    What happened to the original beavers?

    The whole project is addressing the changing climate, but also undoing another man-made issue. The Eurasian beaver had been hunted to extinction in England and Wales more than 400 years ago. At the time, beavers were a valuable source of meat, fur for coats, and castoreum. Castoreum is a secretion from beavers that was used to enhance perfumes and flavor food. Had beavers still thrived, one could argue that the climate change-related flooding might not have occurred in the first place.

    The Ealing Beaver Project is one of several efforts to bring beavers back to the United Kingdom. One of the first attempts to repopulate beavers occurred in Scotland, where Norwegian beavers were introduced to Inverness-shire. Norwegian beavers were chosen because scientists determined they were the most genetically similar to the extinct U.K. beaver population.

    This beaver introduction hasn’t just solved a climate-related flooding problem, but it has also brought other benefits. Visitors and residents enjoy the newly biodiverse nature reserves by going on “beaver safaris” to see the creatures at work in person. Then there is the obvious benefit of the beavers solving these flooding problems effectively free of charge.

    Beavers are an international solution

    The U.K. isn’t the only place using beavers to address climate issues. Beavers were brought in to create dams and conserve river water during droughts in Utah. Similarly, beaver reintroduction into California’s streams and rivers was so beneficial that it was codified into state law.

    This shows that something as funny-looking as a swimming rodent with buck teeth and a paddle tail can make a huge difference in whether a place has enough natural water or too much. Humans just have to give a dam about them.

  • Wildlife reserves and gardens alike can be regrown thanks to dogs wearing backpacks with seeds

    Whether it’s a forest recovering from a wildfire or our own backyards, nature can use some help. Spreading seeds to ensure grass or wildflower growth can be a time-intensive process. However, there is one way that can be fun, quick, and help your dog get some exercise: strapping a backpack full of seeds onto them.

    The practice has been popularized internationally by sisters Francisca and Constanza Torres with their three dogs. Many forested areas of their native Chile were devastated by wildfires. The sisters came up with a plan to help reseed and regrow what had been burned down. The two would strap backpacks filled with grass and wildflowers seeds onto their border collies. The backpack had a small opening that would allow the seeds to fall out and spread as their dogs ran, jumped, and played throughout the area. 

    This helped the forests regrow while also providing the dogs exercise. The dogs were also able to walk into nooks and crannies human planters normally can’t access.

    An idea goes international

    The idea spread past countries and coastlines as a nature reserve in Lewes, East Sussex, England offered dog walkers backpacks with seeds. The walkers would strap the packs onto their furry friends as they went on nature walks to help rewild the area.

    “We’re really interested in rewilding processes, but they often involve reintroducing big herbivores like bison or wild horses,” said the project’s manager Dylan Walker to The Guardian in 2024. “In a smaller urban nature reserve it’s really hard to do those things. So, to replicate the effect that those animals have on the ecosystem we aimed to utilize the vast number of dog walkers that are visiting the nature reserve daily.”

    The concept itself was taken from nature. For centuries, wolves would have seeds caught in their fur. Over time, movement, and grooming, the seeds would be spread throughout other areas of the forest. The wolves acted as natural carriers for seeds much like bees are for pollen.

    Reseed your garden with Rover

    This technique doesn’t have to be reserved for wildfire recovery or regrowing public gardens. Your yard could benefit from it, too. While you could find a pack for your pup and fill it with seeds, there’s another way. Gardener Patrick Vernuccio suggests just filling a tea strainer with seeds and clipping it onto your dog’s collar. It should perform the same effect.

    If you have your dog help seed your yard, be sure that the plants you hope to grow are dog-friendly. Use non-toxic seeds for dogs such as roses, marigolds, and pansies among others. The ASPCA has a full list of plants that are unsafe for dogs to refer to when you’re unsure.

    Man’s best friend can also be man’s best gardening buddy.
