According to studies, humans were getting smarter for thousands of years. Here’s the deal breaker: now they are getting dumber.
Norwegian researchers, Bernt Bratsberg and Ole Rogeberg, have recently published their studies in Proceedings of the National Academy of Sciences, elucidating that human IQs are dropping ever since the 1970s.
The previous trend – Flynn Effect – wherein human minds were found to be brightening at the start of the previous century, is no longer the case.

The conclusions were drawn from 730,000 test results from 1970 to 2009. The subjects used in the research study were the young men joining up compulsory Norwegian military service. The analysis of IQ scores showed a clear drop of seven points on average per generation, revealing a shocking reversal of the IQ results 70 years ago.
The Reasons for Decreasing IQ Scores
The study carried out by Brent and Ole also sheds some light on the possible factors leading to the declining IQs over the past few decades.
Some of the reasons outlined by the researchers include the environmental factors, constantly changing lifestyles with children more inclined towards playing video games instead of reading and changes in the educational system.

If you’re wondering if this is the only study showing such results, you are going to be disappointed.
Ever since the World War II, the IQ levels are dropping by 2.5-4.3 points every decade, as revealed by a team of British researchers.
Not just this, research has linked fish-eating and better sleeping to higher intelligence levels in adults. Kids eating a lot of fish were found to have higher IQs which explains why kids these days are scoring low on IQ scores.
