Japan, Taiwan, and Singapore consistently rank at the top for highest average IQ scores, with Japan often cited as number one (around 106-107), followed closely by Taiwan and Singapore, according to various 2025/2026 reports, though specific rankings can vary slightly depending on the data source, with some sources also highlighting China and South Korea high on the list.
Key Points. Japan ranks first with an average IQ of 112.30. Hungary and Taiwan follow closely with average IQs above 111. The list is based on data from Wiqtcom's 2024 worldwide IQ test.
If you're asking “what is the average IQ in Australia”, data from IQTests.com reports that Australia's average IQ is exactly 100. This aligns with global norms and reinforces that an IQ score of 100 represents the standard benchmark for cognitive ability in both children and adults.
Today, the scientific consensus is that genetics does not explain differences in IQ test performance between groups, and that observed differences are environmental in origin. Pseudoscientific claims of inherent differences in intelligence between races have played a central role in the history of scientific racism.
Lady Gaga's IQ is widely rumored to be around 166, placing her in the "exceptionally gifted" or genius category, though this is an estimation often cited in celebrity lists, not a officially verified number from a public test. This high estimate is supported by her early academic achievements, like attending a summer program for the top 1% of students, and her demonstrated creative and musical genius as a composer and performer, notes Us Weekly and Brainmanager.io.
Studies have shown that intelligence has a genetic component, but they have not conclusively identified any single genes that have major roles in differences in intelligence. It is likely that intelligence involves many genes that each make only a small contribution to a person's intelligence.
The world's largest survey of brain sizes, conducted by American scientists three decades ago using more than 20,000 modern human skulls from around the globe, found that the average cranial volume among East Asians was 1,415 cubic centimetres, compared with 1,362 for Europeans and 1,268 for Africans.
Researchers Helmuth Nyborg and Richard Lynn compared belief in God and IQs. Using data from a U.S. study of 6,825 adolescents, the authors found that the average IQ of atheists was 6 points higher than the average IQ of non-atheists.
United States: In 2022, among people at all income levels, 61% of Asian American adults had BA degree or higher, the highest of all racial/ethnic groups identified by the census.
Terence Tao, an Australian math prodigy with a staggering IQ of 230, is widely regarded as the smartest person alive. Solving college-level problems by age 9 and earning a PhD at 20, he now teaches at UCLA and contributes to advanced fields like number theory and harmonic analysis.
Research shows IQ test scores peak at ages 25-29 and decline afterward, with a steeper drop after age 70.
According to data obtained from Mensa, Finland has the most geniuses per capita, followed by Sweden and the United Kingdom. Mensa was founded in 1946 to create a "society for bright people, the only qualification for membership of which was a high IQ," according to its website.
Careers in the medical field, computer programing, university research positions, and engineering are among the ones with the highest requirements to be smart and have a high IQ.
It is now recognized that there are no significant sex differences in average IQ, though performance in certain cognitive tasks varies somewhat between sexes. While some test batteries show slightly greater intelligence in males, others show slightly greater intelligence in females.
According to the study, Christians in North America, Europe, Middle East, North Africa and Asia-Pacific regions are highly educated since many of the world universities were built by the historic Christian churches, in addition to the historical evidence that "Christian monks built libraries and, in the days before ...
Religious beliefs. Einstein himself stated "I'm not an atheist, and I don't think I can call myself a pantheist ... I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with fates and actions of human beings".
Chimpanzees have been subjected to countless hours of research with the goal of better understanding their cognition. The result is that we can confidently say that chimps are one of the most intelligent species on earth. Humans share 99 percent of our DNA with chimps, so this should come as no surprise.
Brain Development, IX: Human Brain Growth
Although total brain volume is about 95% of its adult size by the age of 5 years, various subcomponents of the brain do undergo age-related changes. In general, white matter—an indication of myelination—increases with age, while gray matter decreases with age.
Leeches have 32 brains. Humans love to think we're the brainiest species around, but leeches have an impressive 32 brains (making them absolute shoo-ins if Mensa ever expands their ranks to include nonhuman animals).
A weighted average has been calculated at 0.75, with about an absolute average difference of 8.0 IQ points. In comparison, identical twins reared together typically differ by 6 IQ points, non-twin siblings differ by 12 points, and complete strangers differ by 16.9 points.
Snoop Dogg has publicly stated he has an IQ of 147, a score that falls into the "highly gifted" or "genius" category, much to his own surprise given his self-described average school performance (straight Cs). While this self-reported score suggests exceptional intellect, IQ tests measure specific cognitive abilities, and success in life and business (like Snoop Dogg's multifaceted career as a rapper, entrepreneur, and media personality) reflects a broader range of intelligence and skills.
Scientists say children inherit most of their intelligence from their mothers, thanks to genes on the X chromosome. Research continues to bolster a long-debated theory: children are more likely to inherit intelligence from their mothers than their fathers.
