KEY POINTS:
Teenagers in England are less intelligent than a generation ago, a study by a New Zealand researcher shows.
Professor James Flynn, of Otago University, found that IQ scores for the average 14-year-old had dropped by more than two points between 1980 and 2008. For those in the upper half of the intelligence scale, average IQ scores were six points down on 28 years ago.
Professor Flynn suggested that the falls could be down to lifestyle changes, including more time spent in front of the television or playing video games.
