Vietnamese took ninth place on a list of countries and territories with the highest average intelligence quotient (IQ), with its average score of 109.37, according to the 2022 Worldwide IQ test results released by Finnish enterprise Wiqtcom Inc. on May 16.

Among over 100 countries and territories whose residents participated in the IQ test, Taiwanese ranked first with an average IQ score of 116.07.

Japan was the second-most intelligent nation with an average IQ of 112.69.

Hungary came in third place with 111.42, followed by South Korea with 111.36, Iran with 111.33, Hong Kong with 111.01, Serbia with 110.09, Italy with 110.87, Vietnam with 109.37, and Finland with 109.02.

The World IQ Test website said IQ test takers in Taiwan scored an "astonishing" average IQ score of 116.07.

This was an enormous improvement on Taiwan's average score of 106.47 in 2019.

Back in 2019, the island ranked second among the most intelligent nations and territories in the world.

Its average IQ scoring was very close to Japan’s 106.49, with a mere 0.02 points separating the average IQ scores for the country and the territory.

Japan's ITMedia said that Taiwan was "one of the most highly educated societies in the world."

According to the Japanese media outlet, the university entrance rate in Taiwan in 2020 reached 84.2 percent and a large number of Taiwanese students continued to pursue their master’s degrees.

However, the Worldwide IQ Test website noted that the reliability of the score for Taiwan is weakened due to the lower number of tests taken in the territory.

The standard deviation for Taiwan was 14.26, which was higher than that of Japan at 12.16.

Wiqtcom Inc. has been testing intelligence on a global scale since 2019.

Its tests are designed to measure cognitive abilities of a person, such as their problem-solving skills, abstract thinking, and general knowledge.

As required by the IQ tests, a test taker needs to be able to speak a particular language, can understand complicated mathematical problems or certain meanings of an issue within the context of a culture.

The IQ tests are given to a number of residents in each country or region.

Wiqtcom’s Worldwide IQ Test website will work out the IQ average score of a nation based on the participants’ testing results.

Its tests currently have a global mean of 100.53 and a standard deviation of 15.14 among all the people who have taken them.
