As research warns IQ is falling for first time EVER.... our map reveals average scores in every US state

Human intelligence scores are dropping crossed nan US for nan first time, investigation suggests, and experts pass exertion could beryllium to blame.

IQ exams were first introduced successful 1905, and passim nan century, location was a 30-point summation based connected scores successful logic, vocabulary, spatial reasoning and ocular and mathematical problem-solving skills. 

The mean IQ people successful nan US presently stands astatine 98 but varies by a spread of astir 8 points betwixt states, pinch New Hampshire ranking first pinch an mean IQ of 103.2.

More investigation needs to beryllium conducted to find why IQ scores are falling crossed nan country, but 1 master speculated that a driblet successful reference and an summation successful media entertainment, for illustration YouTube, is astatine fault. 

There are besides concerns that phones degrade our representation and callback because location is little request to shop accusation pinch Google astatine our digit tips.

Exactly half of US states person an mean IQ of 100 aliases above, pinch New Hampshire, Massachusetts, Minnesota, Vermont coming successful nan apical 4 while North Dakota and Wyoming tied for nan 5th spot.

Meanwhile, those classed successful nan bottommost 5 see New Mexico, Louisiana, Mississippi, Alabama and Nevada, according to World Population Review.

'I do fishy that accrued exertion usage could beryllium playing a domiciled successful impacting our nation's wide literacy levels,' Dr. Stefan Dombrowski, a psychology professor astatine Rider University who studies IQ told DailyMail.com.

'It is good known that group who publication and constitute more, mostly people higher connected IQ tests - of course, this is simply a chicken/egg scenario,' he continued.

'Do these individuals prosecute successful reference and penning activities much often because they are brighter, aliases do they go brighter... connected IQ tests because they publication more?'

Dombrowski said this 2nd mobility is known arsenic nan 'Matthew Effect' wherever a bully scholar will take to proceed to publication much and truthful go much well-read, while mediocre readers will autumn behind.

Researchers person besides suggested that US IQs started slipping astatine nan move of nan millennium arsenic group adopted much exertion into their mundane lives which has only accrued successful caller years.

'Folks are simply not engaging successful reference to nan grade that they erstwhile did,' Dombrowski said.

'They person YouTube and different media sources to entree information, and that aforesaid media is now a root of entertainment, whereas successful nan past, books and different acts of literacy, for illustration writing, played a larger intermezo role.'

Hetty Roessingh, a professor emerita of acquisition astatine nan University of Calgary, antecedently told DailyMail.com that children arsenic young arsenic 5 years aged aren't gathering world benchmarks because integer devices person go truthful accessible.

'There is simply a level of world underachievement, wherever students are under-prepared for college,' Roessingh said.

She added that integer devices are acting arsenic an 'academic displacement of time,' meaning nan clip children walk pinch exertion takes distant from nan clip that could beryllium amended spent doing activities that summation their level of intelligence. 

According to Dombrowski, nan jump successful IQ during nan 1900s could person developed because nan education, healthcare and nutrition successful nan US were improving during that clip and caused what's called nan 'Flynn Effect.'

The Flynn Effect intends that though IQ trial scores had accrued by astir 5 points per decade if nan aforesaid personification were to return an intelligence trial today, they would apt people astir 15 points lower.

Kids that had scored connected nan 'gifted' standard 30 years ago, wouldn't person that aforesaid classification by today's standards, while those who had scored successful nan little scope mightiness people successful nan intellectually abnormal scope successful 2024,' Dombrowski said.

The mean level of wherever a personification should beryllium intellectually is simply a people of 100, and successful comparison, a personification pinch an IQ betwixt 115 and 130 is considered 'gifted' while anyone pinch an IQ betwixt 130 and 145 is branded arsenic a genius. 

But Dombrowski said IQ tests aren't needfully suggestive of a person's existent level of intelligence because it only looks astatine vocational and world success.

Tests should besides attraction connected affectional IQ levels which 'could beryllium an moreover much important component, he said, adding that it 'often leads to occurrence successful life.'

Higher IQ levels are typically correlated pinch happiness and immoderate lit indicates that much intelligent group are besides happier, but Dombrowski pointed retired that isn't ever nan case. 

'There are exceptions,' he said. 'The eminently talented thin to person their intelligence wellness issues. Think of nan lead characteristic successful nan movie 'A Beautiful Mind' who was an eminent mathematician but struggled pinch schizophrenia.

'Think besides of nan precocious Robin Williams who was a comedic brilliant but who suffered from bipolar disorder.

'In effect,' he added, 'eminent giftedness seems to travel astatine a cost.'
