Did the human race reach its intellectual peak between 1930s and 1980s and is now in a downward spiral?

Technology may be getting smarter, but humans are getting dumber, scientists have warned.

Evidence suggests that the IQs of people in the UK, Denmark and Australia have declined in the last decade.

Opinion is divided as to whether the trend is long-term, but some researchers believe that humans have already reached intellectual peak.

Dumb and dumber? Evidence suggests that the IQs of people in the UK, Denmark and Australia have declined in the last decade. Opinion is divided as to whether human intelligence will decrease over time. A study by the University of Hartford claims that the larger the global population becomes, the less intelligent we will be, dropping by around eight IQ points by the year 2110 - and other estimates are even more pesimistic

An IQ test used to determine whether Danish men are fit to serve in the military has revealed scores have fallen by 1.5 points since 1998.

And standard tests issued in the UK and Australia echo the results, according to journalist Bob Holmes, writing in New Scientist.

The most pessimistic explanation as to why humans seem to be becoming less intelligent is that we have effectively reached our intellectual peak.

Between the 1930s and 1980s, the average IQ score in the US rose by three points and in post-war Japan and Denmark, test scores also increased significantly – a trend known as the ‘Flynn effect’.

This increase in intelligence was due to improved nutrition and living conditions – as well as better education – says James Flynn of the University of Otago, after whom the effect is named.

An image of the future? Some experts believe we are starting to see the end of the Flynn effect in developed countries ¿ and that IQ scores are leveling out and even declining. Pessimistic scientists think that our descendants may struggle to understand subjects we can grasp (illustrated with a stock image)
