    Studies show average Finnish intelligence declining since 1997 (Yle Uutiset)
    Nuoria käyttämässä kännyköitä.

    There’s been a gradual decline in average human intelligence in many western countries – including Finland - following decades of steady gains.
    Human intelligence has increased to keep pace with improvements in areas such as nutrition, education and health care. However a 2013 study by scholars at the universities of Ulster, UK and Oulu in Finland found a decline in t...he average IQs of military conscripts on certain tests between 1997 and 2009. …

    “The decline in the average IQ has been detected in several Nordic countries, Australia, Britain, the United States and the Netherlands,” added Helsinki University assistant professor Markus Jokela.
    Jokela stressed that the fall in average intelligence was not dramatic, but was moderate at the level of the wider population.

    Researchers have so far not been able settle on a clear explanation for the fall off in intelligence gains. They have considered factors such as lifestyle, health status and culture. “If we look 30 years backwards at the development of young adults’ health, for at example metabolic risk factors, then there has been a negative development,” Jokela declared.

    He pointed out that the so-called Flynn effect - or the long-term increase of average intelligence in many parts of the world during the twentieth century - was due in part to advances in health care, education and nutrition. The negative Flynn effect could also be tied to health status, he noted.
    Asked whether or not the proliferation of fragmented information common in the age of the internet could account for the dimming of IQs, Jokela responded,“It’s a good question – and controversial. We have seen arguments for and against it,” he concluded.
