A STUDY of people from the north-east of Scotland has shown that people are getting more intelligent with each generation, according to a new study.
Previous research conducted around the world has shown an IQ increase on a scale of three to four points per decade. The so-called Flynn Effect, named after the academic James Flynn, suggests better nutrition, health, higher living standards, and more socio-economic opportunities could contribute to better intelligence through the generations.
Now scientists at Aberdeen University and NHS Grampian have examined research into two groups of 751 people raised in the Granite City. One set was born in 1921 and the other in 1936.
These people are known as the Aberdeen Birth Cohort and were tested when they were aged 11 and when they were adults after the age of 62.
Researchers compared the two groups at age 11 and found an increase in IQ of 3.7 points, which was marginally below what was expected but within the range seen in other studies.
However, comparison in late life found an increase in IQ of 16.5 points, which is more than three times what was expected.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
