IQ of a Rat Compared to a Human: How Smart Are Rats?
There's no real IQ of a rat compared to a human, because IQ is a human-only scale with 100 as the average person. But rats are one of the smartest small animals scientists study: they build mental maps of mazes, learn complex routines, help trapped cagemates, and in one study learned to drive tiny cars. Their brains are close enough to ours in some ways that a lot of memory and learning research starts with rats.
If you've ever gotten lost in a problem the way a rat gets lost in a maze, IQ Tester shows which type of reasoning keeps tripping you up: Find my weak spots.
What is the IQ of a rat?
Straight answer: undefined. The average iq of a rat isn't a thing, because:
- IQ tests use human formats (words, numbers, drawn patterns).
- Your IQ is calculated by comparing you to other humans.
- Rats can't take human tests, and no one has built a rat-scale "IQ."
What scientists measure instead is specific abilities: how fast a rat learns a maze, how well it remembers, how flexibly it adapts when the rules change. That gives a much richer picture of rat intelligence level than any single number.
How smart are rats compared to humans
Obviously, adult humans win overall. But rats are surprisingly good at things we think of as "thinking":
- Spatial memory – rats remember routes and landmarks really well.
- Learning rules – press the lever when the light is on, not off.
- Flexibility – when the maze changes, they find new paths.
- Social behavior – they seem to care about other rats (more on that below).
One fun one: researchers at the University of Richmond trained rats to drive small "rat cars" toward a food reward (2019). The rats learned to steer. That's more than some people manage in a Walmart parking lot.
Rat intelligence compared to human: the brain angle
Rat and human brains share structures, like the hippocampus, which is key for memory and navigation in both species. That's why rats are used so much in memory research. Shared parts don't mean shared smarts, but they mean rat studies can teach us things about how memory works.
What maze studies show
Mazes are the classic rat maze test, and they're basically the rat version of a logic puzzle.
Tolman's cognitive maps
In the 1940s, psychologist Edward Tolman showed rats that explored a maze without a reward could later find the food fast once a reward appeared. His idea: rats build a "cognitive map" in their heads, not just a list of turns. That was a big deal in psychology.
The Morris water maze
Rats swim in a pool of cloudy water to find a hidden platform. Over trials, they learn where it is using cues around the room. If the platform moves, they adjust. Scientists use this to study learning and memory.
What mazes test
| Maze skill | Human version |
|---|---|
| Remembering where things are | Knowing where you parked |
| Using landmarks | Finding a classroom by the vending machine |
| Updating when rules change | Your bus route changes and you adapt |
| Avoiding repeat dead ends | Not making the same mistake on a test twice |
Rats vs mice
"Are rats smarter than mice?" Generally, rats are seen as faster learners on many tasks and are more often trained on complex ones, while mice are used a lot for genetics research. Both are smart for their size. Rats also tend to be calmer with handling, which is why they're popular as smart pets.
How smart are rats compared to dogs?
Rat intelligence vs dog is a weird matchup. Dogs read human gestures far better because of domestication. Rats beat a lot of animals on maze-style spatial memory. For more farm and pet comparisons, see our posts on the IQ of a pig and the IQ of a squirrel, which compares squirrels directly with rats.
Rat empathy and problem-solving
This is the part that makes people rethink rats.
- Freeing a trapped friend: a 2011 study in Science (Bartal, Decety and Mason) found that rats learned to open a small restrainer to free a trapped cagemate, and often did it even when chocolate was also on offer, sometimes sharing the chocolate afterward.
- Laughing when tickled: neuroscientist Jaak Panksepp's research found rats make high-pitched ultrasonic calls when tickled, which he linked to play and positive emotion.
- Problem solving: rats figure out puzzle boxes, levers and sequences in labs.
So "do rats have empathy?" Researchers debate the exact word, but they do show behavior that looks a lot like helping.
Here's the thing about mazes: from the inside, you can't see the whole map. Same with your own thinking; you can't easily tell which "turn" you keep getting wrong. IQ Tester does the mapping: 20 untimed questions across number series, verbal analogy, logic and pattern, and a breakdown that shows which category is your dead end. Find my weak spots
What mazes have in common with IQ puzzles
A maze and an IQ puzzle ask the same thing: can you find the rule and use it?
- Spot the structure. In a maze, it's the layout; in a number series, it's the pattern (+2, +4, +8...).
- Hold it in your head. Rats track turns; you track steps of logic.
- Update when wrong. A dead end tells a rat something. A wrong answer should tell you something too.
- Practice changes speed. Rats get faster with trials. So do people with short daily practice.
Real talk: if a rat can learn a maze through repetition, you can learn number series questions the same way. That's the whole idea behind short daily drills.
Map your own maze in a minute
Your score can actually be measured, unlike the iq of a rat compared to a human. Sign in to IQ Tester with Google or Apple and start 20 untimed questions, easiest first. You'll see your band and three of your four category strengths free, then the guides give you one short drill a day on your weak spot. It's for entertainment, not a clinical assessment.
FAQ
What is the average IQ of a rat?
There isn't one. IQ is a human scale, so rats can't have a real score. Scientists measure specific skills like maze learning and memory instead.
How smart are rats compared to humans?
Far below adult humans overall, but strong at spatial memory, learning rules and social behavior. Rats and humans share brain areas like the hippocampus, which is why rats are used in memory research.
Are rats smarter than mice?
Rats are generally considered faster learners on many complex tasks, while mice are often used for genetic research. Both are clever for their size.
How smart are rats compared to dogs?
Dogs are much better at reading humans. Rats are excellent at spatial and maze-style tasks. It depends which skill you compare.
Do rats really have empathy?
A 2011 study found rats learned to free trapped cagemates, even when chocolate was available. Scientists debate whether to call it empathy, but it looks a lot like helping behavior.
