How High IQ Influences Your Mental Health

Along with fewer depression symptoms, it was also linked to better sleep.

Along with fewer depression symptoms, it was also linked to better sleep.

Higher intelligence reduces the risk of mental health problems, including depression, research finds.

A higher IQ is linked to less self-reported depression symptoms, fewer sleep problems and better overall mental health.

The conclusions come from a study of 5,793 people who were followed for decades.

The results showed that those with higher IQ scores in their youth had better overall mental health when they were 50-years-old, compared to those with lower IQs.

Along with fewer depression symptoms, those with higher IQs also slept better in middle age.

The authors conclude that IQ may have a protective effect against depression in middle age:

“Higher pre-morbid intelligence was significantly associated with less depression, less sleep difficulty, and a better overall mental health status at age 50.

These results were similar to those found at age 40 and they suggest that higher intelligence in youth, in both men and women, may have a protective effect on mental health into middle age.”

However, people with higher IQs were more likely to have received a depression diagnosis by age 50.

This seems to contradict the finding that they self-reported lower symptoms of depression.

The researchers think it may be because intelligent people are more likely to recognise depression and get help for it.

They write that one possible reason is that:

“…people with higher intelligence may also have higher mental health literacy.

Those with higher intelligence might be more able to identify their symptoms of depression, which could motivate them to consult a doctor for diagnosis and advice; they might also be likely to have accurate reporting of such diagnoses in the health module.”

The study was published in the journal Intelligence (Wraw et al., 2018).

The Patient Sign Of High Intelligence

Do you pass the financial test of intelligence?

Do you pass the financial test of intelligence?

People with high IQs are more patient in financial matters, research finds.

They are willing to wait longer to increase their money and to endure the risks involved.

The survey of 1,000 people in Germany tested how long people would wait for a series of rewards, analogous to putting it into a savings account.

For example, people were given $100 to have now, or they could choose to wait one year to get more.

Would you wait one year to get $110, $120 or $150?

Or would you rather just have the $100 right now?

Professor Armin Falk, study co-author, summarised the results:

“The more intelligent the test subjects were, the more patient and tolerant of risk they were.”

Impatient people generally wanted a higher reward for waiting one year to get their money.

Intelligent people did not demand so much reward for taking the risk.

It seems that intelligence, risk tolerance and patience are closely related.

It is important to see the connections between risk and reward.

Professor Falk said:

 “Anyone who does not have this ability may be better advised to follow the principle of ‘A bird in the hand is worth two in the bush.'”

The study was published in the American Economic Review (Dohmen et al., 2010).

This Will Lower A Person’s IQ By 30%

The statement that massively reduces a person’s IQ.

The statement that massively reduces a person’s IQ.

Being socially rejected massively reduces a person’s effective IQ, research finds.

People told, “you will end up alone in life” experienced drops in analytical reasoning skills of 30 percent.

Their IQs also dropped around 25 percent.

Not only does rejection lower IQ, it also makes people more aggressive, other studies have shown.

The results suggest that intelligence may have evolved primarily to facilitate social relations.

For the study, people took a personality test and some were then told (falsely) that it indicated they would end up alone in life.

Afterwards they were given an IQ test.

The study’s authors explain the results:

“In all three studies, people exhibited significant cognitive decrements after they were told that they were likely to end up alone in life.

Thus, the prospect of social exclusion reduced people’s capacity for intelligent thought.

Moreover, the decrements in intelligent performance qualified as large effects every time.”

The researchers think that people’s IQ drops because they are in distress:

“…we can best explain the pattern of cognitive decrements by proposing that social exclusion constitutes a threatening, aversive event but that people strive to suppress their emotional distress, and the resulting drain on their executive function impairs their controlled processes.”

In other words, being told they would end up alone made it harder for them to concentrate, because they were trying to suppress negative emotions.

There is an intimate link between intelligence and social relations, the authors write:

“Our results are more consistent with the view that
intelligence evolved as a means to support and facilitate social relations rather than to compensate for the absence of their advantages.

[…]

Our findings could even be taken to suggest that people responded as if being excluded from social groups removed the need for intelligent thought.”

The study was published in the Journal of Personality and Social Psychology (Baumeister et al., 2002).

The Common Drink Linked To A Lower IQ

The drink is consumed by 86% of Americans and is popular around the world.

The drink is consumed by 86% of Americans and is popular around the world.

Drinking higher levels of alcohol and binge drinking are both linked to a lower IQ, research finds.

People with higher IQs tend to avoid binge drinking.

The conclusions come from a study of 49,321 Swedish men conscripted for military service between 1969 and 1971.

They were given IQ tests and asked about their alcohol intake.

The lower their IQ was, the more they drank and the more likely they were to binge drink.

It is not clear from the study exactly how IQ is linked to alcohol intake.

However, it is likely that lower IQ is linked to lower social status and emotional problems, both of which may drive higher rates of alcohol consumption.

The study’s authors conclude:

“We found that lower results on IQ tests are associated with higher consumption of alcohol measured in terms of both total alcohol intake and binge drinking in Swedish adolescent men.”

People with higher IQs tend to be healthier, the authors explain:

“One suggested explanation for the association between intelligence and health is that cognitive skills enhance possibilities to make healthy lifestyle choices.

Cognitive ability has been found to be associated with several health-related behaviors, such as smoking, food intake, and physical activity.”

Previous studies have also linked binge drinking to lower IQ.

However, in that study, people with higher IQs had higher levels of average alcohol consumption.

The results fit with the fact that highly intelligent people are also more likely to use drugs.

It could be because the intelligent tend to be easily bored.

At the same time, though, they also led healthier lifestyles.

The divergence between the studies could be down to different populations.

The study was published in the Alcoholism: Clinical and Experimental Research Journal (Sjölund et al., 2015).

A Thoughtful Childhood Sign Of High IQ

One common sign of high IQ is obvious in childhood.

One common sign of high IQ is obvious in childhood.

Learning to read at an earlier stage is a sign of higher IQ, a study finds.

The better a person’s reading skills at age 7, the higher their intelligence in later life.

It may be that reading from an earlier age helps to improve IQ.

If this is true, then helping children to read sooner may boost their intelligence.

Dr Stuart J. Ritchie, the study’s first author, said:

“Since reading is an ability that can be improved, our findings have implications for reading instruction.

Early remediation of reading problems might aid not only the growth of literacy, but also more general cognitive abilities that are of critical importance across the lifespan.”

The conclusions come from a study of 1,890 twins whose IQ and reading levels were tested between the ages of 7 and 16.

Twins were included because the researchers wanted to rule out the effect of the environment and genes.

It emerged from the results that among each pair of twins, the one that began to read earlier had a higher IQ later on.

Dr Ritchie said:

“If, as our results imply, reading causally influences intelligence, the implications for educators are clear.

Children who don’t receive enough assistance in learning to read may also be missing out on the important, intelligence-boosting properties of literacy.”

Dyslexia

Dyslexia — a type of learning difficulty causing problems with reading and writing — is not a sign of low IQ.

Professor John D. E. Gabrieli, who has published research on dyslexia and IQ, said:

“We found that children who are poor readers have the same brain difficulty in processing the sounds of language whether they have a high or low IQ.

Reading difficulty is independent of other cognitive abilities.”

The study was published in the journal Child Development (Ritchie et al., 2015).

Why Rebellious Drug-Takers Have Higher IQs

Intelligent people often value novel things and also tend to be offbeat and rebellious.

Intelligent people often value novel things and also tend to be offbeat and rebellious.

People with high IQs are more likely to consume mind-altering substances, research finds.

Whether it is alcohol, tobacco or psychoactive drugs like LSD, intelligence and drug-taking are linked.

More intelligent people are also more likely to have sampled a variety of different recreational drugs in the past.

The explanation could be that intelligent people are attracted to novelty or that they do not fear becoming addicted due to higher self-control.

Offbeat and rebellious

On top of this people with higher intelligence are more likely to be original, offbeat and rebellious, research finds.

More intelligent people have a distinct, individual style and avoid following the crowd.

Non-conformists may be more intelligent because they are less afraid to break society’s conventions.

The conclusions come from a small study that asked 46 people about their ‘need for uniqueness’ and tested their intelligence.

They were asked whether they agreed with statements like:

  • “I do not always need to live by the rules and standards of society.”
  • “I tend to express my opinions publicly, regardless of what others say.”
  • “When a style of clothing I own becomes too commonplace, I usually quit wearing it.”

The results showed that people with higher IQs were more likely to endorse statements indicating a preference for uniqueness.

More intelligent people may be more resourceful, which explains their independence, the study’s authors write:

“…the more intelligent someone is, the less dependent this person is on the group to acquire resources.

This means that highly intelligent people can afford more non-conformist behavior because of their capacity to secure resources in isolation.

…as general intelligence increases the need to conform to group norms decreases.”

These findings fit with another study that has found that people with high IQs drink more alcohol, although they are unlikely to be heavy drinkers.

Another possibility is that more intelligent people are more likely to get bored.

The Mark Of A High IQ Brain

The findings for fluid intelligence — the brain’s raw speed — were different for men and women.

The findings for fluid intelligence — the brain’s raw speed — were different for men and women.

The brains of people with high IQ have very efficient wiring, research shows.

The brain’s ‘wiring’ or ‘white matter’ refers to the nerve fibres that transmit information between areas.

White matter is sometimes called the superhighway of the brain: it transmits signals and regulates communication.

People with more efficient white matter, the study found, had greater general knowledge.

General knowledge — or as psychologists call it, crystallised intelligence — is one of two broad aspects of intelligence.

Dr Erhan Genç, the study’s first author, said:

“Although we can precisely measure the general knowledge of people and this wealth of knowledge is very important for an individual’s journey through life, we currently know little about the links between general knowledge and the characteristics of the brain.”

For the study, 324 were given brain scans and asked to answer a series of general knowledge questions.

The results showed that people with more efficient structural networks in their brain got more general knowledge questions correct.

Dr Genç said:

“We assume that individual units of knowledge are dispersed throughout the entire brain in the form of pieces of information.

Efficient networking of the brain is essential in order to put together the information stored in various areas of the brain and successfully recall knowledge content.”

The findings for fluid intelligence — the brain’s raw speed — were different for men and women.

Men, it emerged, who had bigger brains tended to have higher fluid intelligence.

Women with better functional connectivity, though, had higher intelligence.

Efficient brain networking is vital for intelligence, said Dr Genç:

“We assume that more efficient networking of the brain contributes to better integration of pieces of information and thus leads to better results in a general knowledge test.”

The study was published in the European Journal of Personality (Genç et al., 2019).

The Social Situation That Causes Your IQ To Drop Dramatically

The drop comes about because of subtle social signals sent between people about their place in the hierarchy.

The drop comes about because of subtle social signals sent between people about their place in the hierarchy.

Being in a group can make some people lose around 15 percent of their IQ, research finds.

People who tried to solve problems in a group behaved as though they were significantly less smart than their IQ scores suggested.

The drop comes about because of subtle social signals sent between people about their place in the hierarchy.

In other words, some people start to feel inferior in a group and this affects their ability to think clearly.

Professor Read Montague, who led the research, explained how it worked:

“We started with individuals who were matched for their IQ.

Yet when we placed them in small groups, ranked their performance on cognitive tasks against their peers, and broadcast those rankings to them, we saw dramatic drops in the ability of some study subjects to solve problems.

The social feedback had a significant effect.”

In the real world, social signals can be sent in more subtle ways than announcing everyone’s performance.

It could be a social hierarchy known to everyone, how people speak or even their gender.

Women are particularly vulnerable to an IQ drop from being in a group, the researchers found.

Dr Kenneth Kishida, the study’s first author, said:

“Our study highlights the unexpected and dramatic consequences even subtle social signals in group settings may have on individual cognitive functioning.

And, through neuroimaging, we were able to document the very strong neural responses that those social cues can elicit.”

Professor Montague concluded:

“You may joke about how committee meetings make you feel brain dead, but our findings suggest that they may make you act brain dead as well.”

The study was published in the journal Philosophical Transactions of the Royal Society B (Kishida et al., 2012).

Why Smart People Are Prone To Mental Illness

The risk of mental illness is up to 4 times higher in those with a high IQ. Why?

The risk of mental illness is up to 4 times higher in those with a high IQ. Why?

Highly intelligent people are at increased risk of mental illness, according to research.

This is because the brains of intelligent people are hyperexcitable, the researchers think.

A higher IQ leads to a greater awareness of their surroundings and what is going on.

This causes the central nervous system to be more reactive, making intelligent people more ‘jumpy’.

Dr Nicole Tetreault, study co-author, said:

“A minor insult such as a clothing tag or an unnatural sound may trigger a low level, chronic stress response which then activates a hyper body response.

When the sympathetic nervous system becomes chronically activated, it finds itself in a continuous fight, flight, or freeze state that triggers a series of immune changes in both the body and the brain-altering behavior, mood, and functioning.”

The conclusions come from a survey of 3,715 members of MENSA, whose members all have high IQs (above 130).

They reported their own mood and anxiety disorders as well as other conditions such as ADHD, autism and any physiological problems.

This data was compared to the national averages for these conditions.

Ms Audrey Kinase Kolb, study’s co-author, said:

“If high intelligence was not a risk factor for these diseases and disorders, we would see a similar prevalence rate between the two groups.

However, in this study, the Mensa population had significantly higher rates across the board.

For example, just over 10% of the US has a diagnosed anxiety disorder, compared to 20% for Mensans.

For these conditions, having a high intelligence is related to having between 2 to 4 times the chance of having a diagnosis compared to the average American.”

Ms Ruth Karpinski, the study’s first author, said:

“While falling within the extreme right tail of the Bell Curve is generally touted as a ‘gift’ leading to exceptional outcomes, this is not always the case.

Those with high IQ possess unique intensities and overexcitabilities which can be at once both remarkable and disabling on many levels.”

The study was published in the journal Intelligence (Karpinski et al., 2017).
