A variety of cognitive research on chimpanzees places their estimated IQ between 20 and 25, around the average for a human toddler whose brain is still developing the ability to use various cognitive abilities.
Dolphin Brain vs Human Brain: Encephalization Quotient
The encephalization quotient is the ratio between the real and predicted brain mass of an animal-based on its body size. For human beings, the encephalization quotient is higher than any other animal at 6.56. Dolphins are not too far behind at 4.0 EQ.
The average dog's IQ is about 100. Based on the results done to test a dog's IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
The encephalization quotient (EQ) (the size of the brain relative to body size) of elephants ranges from 1.13 to 2.36. The average EQ is 2.14 for Asian elephants, and 1.67 for African, with the overall average being 1.88.
In general, an IQ score is defined with a median and mean of 100. Scores above 130 are labeled as above average or “very superior,” while scores under 70 would be considered below average or labeled as “borderline impaired.” Most people have an average IQ between 85 and 115.
85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted.
There is no zero point for IQ. We do not think of a person as having no intelligence (although we may be tempted to make that evaluation upon occasion).
Pigs have the intelligence of a human toddler and are ranked as the fifth most intelligent animal in the world! In fact, pigs are more intelligent and trainable than any breed of dog. They learn their names in just two weeks and come when they're called.
1: Chimpanzee
Chimpanzees can learn sign language to communicate with humans. Topping our list of smartest animals is another great ape, the chimpanzee. The impressive intellectual abilities of this animal have long fascinated humans.
Within the encephalization quotient proposed by Jerison in 1973, values above one are classified big-brained, while values lower than one are small-brained. The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8.
William James Sidis has the World's Highest IQ. Anywhere from 250 to 300 is his IQ score, almost twice the score of Albert Einstein. At the age of eleven, William famously entered Harvard University, becoming the youngest person to enter.
The average IQ varies from country to country, with the US standing at 98. Anything above 130 is high. Here are some of the glimpses of genius that attest to Bill Gates' high IQ, even to the point of being a 160 score.
Octopuses have demonstrated intelligence in a number of ways, says Jon. 'In experiments they've solved mazes and completed tricky tasks to get food rewards. They're also adept at getting themselves in and out of containers.
Scientists compare the intelligence of crows to that of a seven-year-old human child. Crows, ravens, and other corvids are the only non-primates that make tools. Crows are capable of abstract reasoning, complex problem-solving, and group decision-making.
If we could turn all the animals into humans to take the IQ test, octopuses would outscore most humans on the math portion at a genuis level of above 140. They would also do very very well at spatial visual.
Chimpanzees
We share 99 percent of our DNA with chimpanzees, so it comes as no surprise that countless hours of research have been dedicated to understanding the intelligence and behavior of our sister species. This research has firmly established that chimps are one of the most intelligent species on earth.
According to research, cows are generally quite intelligent animals who can remember things for a long time. Animal behaviorists have found that they interact in socially complex ways, developing friendships over time and sometimes holding grudges against other cows who treat them badly.
Horses are considered to be one of the most intelligent animals on Earth, due to their ability to learn quickly and remember things. They can also solve problems, figure out how to get something, and even understand human language.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
Like other variable human traits (height, for example), the range of IQ is on a standard curve bell curve. Most people you meet are probably average, and a few are extraordinarily smart. Just 2.2 percent have an IQ of 130 or greater.
There's no record of the lowest IQ ever. However, the lowest IQ score possible is zero.
One of the most well-known online exams available to you is Free-IQTest.net. It has 20 questions that will measure your IQ score accurately. After this test, you have to give your birth date since the test calculates your IQ score based on your age. This way, you may compare yourself to your peers.
