How Mabel the Pig Broke the Touchscreen Intelligence Test

The first time the pig completed the puzzle, the laboratory fell silent. There was no hum from equipment or flicking of notebook pages, only researchers watching a pink snout steadily press a touchscreen. The display showed a group of shapes that continually switched places: an animal IQ test intended to catch out even intelligent dogs. Below it stood Mabel, a pig with her head slightly cocked and eyes narrowed as though she were deciphering a line of code.

One press, followed by another more quickly.

The display lit up green. Mabel had finished before the timer ran out.

A scientist muttered an expletive. Another person gave a nervous laugh. Entirely unconcerned, the pig snorted and waited for her reward.

She completed it even more quickly on her second attempt.

At that point, the story ceased to seem merely charming and began to feel faintly disconcerting.

What did this pig know that we did not?

The day a farm pig broke the test

The intelligence test was never intended to make headlines. It had been planned as a modest side experiment in a busy animal-cognition laboratory investigating touchscreen tasks. The arrangement was almost absurdly funny: a tough tablet mounted at pig height, a straightforward game involving moving symbols, and a large, inquisitive sow whose world had until recently consisted of mud and feed troughs.

The researchers assumed she would prod at it awkwardly, become bored or simply hold out for an effortless reward. Instead, Mabel started following the patterns. Her gaze tracked the moving icons. She selected the correct shape repeatedly, reducing her reaction time by seconds as though she had spent years playing games.

The test had not failed. The researchers’ expectations had.

The origins of the surprise matter. Mabel came from a small family farm and had largely been chosen because she was placid and straightforward to manage. The team had given comparable tasks to dogs: follow an image, touch the appropriate symbol and recall what had just appeared on the display. Many dogs took days to understand the game, while some never fully grasped it.

Mabel required two brief sessions. By the third day, she had moved to the advanced stage, in which the right symbol appears for only a fraction of a second before disappearing. She began to predict what was coming. When the researchers introduced a complication - a false symbol intended to mislead her - she paused once before learning to disregard the decoy. A farm pig raised around hay bales and metal gates was now matching an above-average border collie in a digital memory test.

The figures changed the atmosphere in the room. Across several tasks, Mabel’s success rate was around 80%, and, in one memory challenge involving four shifting positions, she finished nearly twice as quickly as the average dog previously tested in identical conditions. Pigs had long been broadly described as “intelligent”, but seldom with measurable, repeatable results that seemed so unnervingly… human.

One researcher called it “watching someone you underestimated solve your own password.” Another discreetly adjusted future experiments after recognising that the standard had been set too low. Once you’ve seen a pig treat your touchscreen like a toy, it’s hard to go back to calling them livestock without thinking twice.

What a pig’s puzzle skills really say about us

On paper, the touchscreen task that startled the team was uncomplicated: the animal has to learn that selecting a particular symbol earns a reward, then follow that symbol as it moves about the screen. As the exercise continues, the delays become briefer, distractions become louder and patterns grow less orderly. For people, it resembles the sort of training app you would abandon after three attempts. For Mabel, it became familiar routine.

The team then introduced small additional tests: a short sound before the symbol appeared, a delayed reward and occasional random “empty” trials with no treat at all. They anticipated frustration. Mabel continued regardless. She adjusted to the unfulfilled promise of food and still selected the right symbol, as if the cognitive challenge had become rewarding in itself.

Many people who work with pigs were unsurprised. Farmers describe pigs unfastening latches, recalling feeding times and even learning which person in the yard hands out extra scraps. After hearing about the experiment, one farmer simply said, “She probably thinks you’re the slow ones.”

In another recorded example, a pig on a separate farm learned to raise a gate bolt with her snout. Whenever the farmer altered the mechanism, the pig observed it, waited and worked out the new arrangement within a few days. That is more than instinct; it is persistence combined with memory. Add this sort of problem-solving to a touchscreen challenge and the same essential ingredients emerge: curiosity, reward and a mind that persists when a problem becomes strange.

For years, scientists have compared animal intelligence with mazes, levers and pattern-recognition exercises. Dogs excel at social signals, horses at spatial awareness and crows at using tools. Pigs were generally placed in the category of “quite smart, especially with food”, and rarely considered further. Touchscreen tests are beginning to reorganise that mental classification.

When a pig not only completes a puzzle but gets better at it, predicts changes and carries on even without a sweet dropping out, researchers are measuring more than hunger. They are approaching something more like adaptable thought. And, honestly, few people spend every day calmly reassessing their assumptions about what animals can and cannot comprehend. Yet that is the understated question now confronting everyone around Mabel as she taps at the screen.

How this pig’s story may reshape our behaviour

What should people do with the knowledge that a farm pig can excel at a digital memory test? One practical response already being adopted by some researchers is to rethink enrichment for pigs in laboratories and on farms. Rather than dropping random toys into a pen, they are testing interactive objects that vary over time, including puzzle feeders, sound panels and even basic button games that give different responses each day.

The principle is straightforward: offer the pig something that responds to her decisions, rather than merely something to chew. Provide patterns, not only pellets. Such an environment does more than occupy her; it acknowledges the mental machinery working behind the snout.

For those who keep or work with pigs, the larger change happens internally. Seeing a pig resolve a problem as it happens makes it more difficult to regard pigs as interchangeable units. Some farmers quietly acknowledge that they speak to their pigs, tell them what is happening when they are moved and even apologise when circumstances become stressful.

A frequent misunderstanding is that “more stimulation” simply means additional noise or more gadgets. Pigs do not require a farm-scale theme park. They need challenges suited to their minds: something to solve instead of merely something to tolerate. If that thought feels weighty or uneasy, that is understandable. We have all experienced the moment when fresh information tugs at an old habit that had seemed secure.

Researchers studying Mabel and pigs like her often refer to an unusual emotional delay: their data changes more rapidly than their feelings. The mind needs time to catch up with the spreadsheet.

“Once you measure their learning curve with the same tools you’d use for a dog or a toddler app,” one scientist told me, “you can’t unsee it. You start wondering what they’re thinking while they wait for you to catch up.”

• Give them real puzzles – Even straightforward tasks with changing rules make use of their problem-solving skills.
• Watch for boredom – Repetitive actions, chewing the same area and restless pacing may all indicate that the brain is underused.
• Respect the learning speed – Pigs that quickly master one task may need a faster progression to remain interested.
• Notice individuality – Not every pig will be a “Mabel”, and that variation is itself part of their cognitive richness.
• Let the evidence sink in slowly – It is fine if your feelings about pigs change over weeks rather than immediately.

When the animal looking back at you won’t fit in the old box

Accounts such as Mabel’s do not settle a debate; they open one up. Once the figures are available - reaction times, success rates and error patterns that closely resemble human learning curves - the question shifts from “are pigs smart?” to “what does their intelligence ask of us?” That is a different sort of test, and this time humans are the ones struggling with the screen.

You may never enter a laboratory or hold a touchscreen up to a pig, but these findings quietly reach into everyday life. They appear on your plate, in your children’s questions and in your response when you next pass a lorry carrying animals on the motorway. They challenge the stories we tell about the divide between humans and every other animal.

Perhaps the most troubling element is not that a pig completed complex puzzles faster than anticipated. Perhaps it is that she showed no surprise whatsoever. She did the task, accepted the treat and patiently waited for people to catch up with what her brain was already demonstrating on the glowing glass before her.

FAQ:

• Question 1 Are pigs really as smart as dogs?

Answer 1

Pigs do not think in the same way as dogs, but in particular tests - involving memory, pattern learning and problem-solving - they can often perform at a comparable or higher level. They may be less able to interpret human gestures than dogs, yet they can learn complicated tasks requiring concentration and adaptability.

• Question 2 What kind of puzzles did the pig solve?

Answer 2

The pig used a touchscreen displaying moving symbols. She had to remember which symbol was “correct”, follow it as it moved position, disregard distracting decoys and respond fast enough to beat a timer, much like simplified human cognitive games.

• Question 3 Was this just about food rewards?

Answer 3

Food provided part of the motivation, but the pig continued to perform when rewards were delayed or sometimes absent. That persistence, together with her ability to adjust as the rules changed, points to a kind of engagement beyond a simple reflex.

• Question 4 Does this change anything about how pigs should be treated?

Answer 4

The data does not issue moral instructions, but it leaves fewer grounds for dismissing pigs as unthinking. Many scientists and some farmers already use these findings to advocate richer environments and more considered handling methods.

• Question 5 Could other farm animals do the same tests?

Answer 5

Yes, and some have already done so. Cows, sheep and chickens are being assessed with comparable tools, although screen-based tasks are not equally suitable for every species. Early findings indicate that farm animals’ mental lives are considerably more complex than old stereotypes ever suggested.
