This Charming Personality Trait Is A Sign Of High IQ

The trait is not normally associated with intelligent people.

The trait is not normally associated with intelligent people.

People who are generous by nature have a higher IQ, research finds.

Generous people are unselfish and sometimes deny themselves so that others can have more.

Although generosity is not something people usually associate with intelligence, psychological research clearly shows a link.

Intelligent people may be more generous partly because they can afford it.

People with higher IQs generally have greater resources, or can expect to recover what they have given away later on.

The conclusions come from a study in which 96 people played games that involved either donating to others or keeping things for themselves.

The results revealed that intelligent people were more generous to others.

In contrast, those who kept more for themselves tended to be less intelligent.

The study’s authors used the results of SAT tests, which can be converted into approximate IQ scores.

They write:

“We find that subjects who perform better on the Math portion of the SAT [Scholastic Aptitude Test] are more generous in both the dictator game and the SVO [Social Value Orientation] measure.

[…]

Our results involving SAT scores […] suggest that measures of cognitive ability, which are less sensitive to the intrinsic motivation of the subject, are positively related to generosity.”

The study was published in the Journal of Economic Behavior & Organization (Chen et al., 2013).

6 Intriguing Psychology Studies On Human Intelligence

Answers to: Is IQ dropping around the world? Where does human intelligence come from? What are the signs of a high IQ brain?

Answers to: Is IQ dropping around the world? Where does human intelligence come from? What are the signs of a high IQ brain?

While it is obvious to us that some people are smarter than others, scientists are definitely not agreed on the root of one of our most precious abilities: intelligence.

Certainly, many aspects of intelligence are mysterious, and these six recent studies published in the members-only section of PsyBlog have asked questions including:

  • Where does human intelligence come from?
  • What are the signs of a high IQ brain?
  • Is IQ dropping around the world?

Perhaps the last of these questions should concern us the most; after all, without our intelligence what a paltry being is left?

A Very Popular Drink Is Linked To Lower IQ

The ‘refreshment’ is linked to a slower brain and making more mistakes.

The ‘refreshment’ is linked to a slower brain and making more mistakes.

Drinking higher quantities of alcohol and smoking cigarettes are both linked to a lower IQ, research finds.

People who smoke and drink have a worse memory and poorer problem-solving skills.

Similarly, higher rates of binge drinking are also linked to a lower IQ, a previous study found.

Smoking may be even more damaging to thinking skills than drinking.

High levels of smoking and drinking both lead to a slower brain and making more mistakes.

The reason may be that smoking and drinking damage the blood vessels supplying the brain.

The conclusions come from a study of 172 men, some of whom were alcoholics.

All completed tests of IQ, memory and thinking skills and were followed up over nine years.

The results showed that the more they drank and smoked, the lower their IQ.

Drinkers and smokers also had worse memories and poorer thinking skills.

Dr Jennifer Glass, the study’s first author, said:

“We can’t say that we’ve found a cause-and-effect relationship between smoking and decreased thinking ability, or neurocognitive proficiency.

But we hope our findings of an association will lead to further examination of this important issue.

Perhaps it will help give smokers one more reason to quit, and encourage quitting smoking among those who are also trying to control their drinking.”

Professor Robert Zucker, study co-author, said:

“The exact mechanism for smoking’s impact on the brain’s higher functions is still unclear, but may involve both neurochemical effects and damage to the blood vessels that supply the brain.

This is consistent with other findings that people with cardiovascular disease and lung disease tend to have reduced neurocognitive function.”

The study was published in the journal Drug and Alcohol Dependence (Glass et al., 2006).

Why Being A Daydreamer Is A Sign Of High IQ And Creativity

People with efficient brains tend to have spare capacity.

People with efficient brains tend to have spare capacity.

Daydreaming is a sign of being more creative and having higher intelligence, research suggests.

Those who report more daydreaming have higher intellectual abilities and their brains work more efficiently.

People with efficient brains tend to have spare capacity, so it is natural for the mind to wander.

Wandering minds and intelligence

The conclusions come from a study in which over 100 people stared at a fixed point for five minutes while their brains were scanned.

The aim was to see how the areas of the brain worked together when they were given nothing in particular to do.

The results showed that those with more efficient brains were also smarter and more creative.

Dr Eric Schumacher, study co-author, said:

“People with efficient brains may have too much brain capacity to stop their minds from wandering.

People tend to think of mind wandering as something that is bad.

You try to pay attention and you can’t.

Our data are consistent with the idea that this isn’t always true.

Some people have more efficient brains.”

Brain efficiency insights

One sign of an efficient brain is being able to zone in and out of conversations without missing anything.

Dr Schumacher said:

“Our findings remind me of the absent-minded professor — someone who’s brilliant, but off in his or her own world, sometimes oblivious to their own surroundings.

Or school children who are too intellectually advanced for their classes.

While it may take five minutes for their friends to learn something new, they figure it out in a minute, then check out and start daydreaming.”

Ms Christine A. Godwin, the study’s first author, wants to examine exactly when mind wandering could be useful and when not:

“There are important individual differences to consider as well, such as a person’s motivation or intent to stay focused on a particular task.”

The study was published in the journal Neuropsychologia (Godwin et al., 2017).

This Personality Trait Is A Sign Of High Fluid Intelligence

Fluid intelligence refers to the raw speed at which the brain works.

Fluid intelligence refers to the raw speed at which the brain works.

A hunger for new, unconventional ideas is one of the strongest indicators of high IQ, research finds.

People with high IQs are intellectually curious and enjoy things like unusual activities, philosophical arguments and brain teasers.

This desire for new ideas is linked to an aspect of IQ called fluid intelligence.

Fluid intelligence refers to the speed at which the brain works.

It is like the raw power of an engine or the speed at which a computer can process information.

Fluid intelligence is contrasted with crystallised intelligence.

Crystallised intelligence is something like general knowledge: the information that people have learnt about the world over the years.

The conclusions come from a study of 2,658 employees working at 10 different companies in the UK.

They were all given tests of personality and intelligence.

The results showed that high fluid intelligence was linked to hunger for new ideas.

Like an interest in ideas, being willing to try new activities was also linked to intelligence, the authors write:

“Actions refers to willingness to try different activities, and to a preference for novelty and variety over familiarity and routine.

Fluid intelligence involves things like reaction times, quick thinking, reasoning, seeing relationships and approaching new problems.

This means that individuals high on [fluid intelligence] have an innate ability to cope more efficiently with novel experiences, and to deal with intellectually stimulating tasks such as brain teasers, which would thus make it rewarding for them to pursuit such activities.

Similarly, individuals low on [fluid intelligence] may in time grow to avoid such activities, due to their low ability to handle them, which would thus make them less rewarding.”

The study was published in the journal Learning and Individual Differences (Moutafi et al., 2006).

A Delightful Sign That You Have A High IQ

People with high IQs tend to share this quality.

People with high IQs tend to share this quality.

More intelligent people tend to follow rules and be less aggressive and better behaved, research finds.

People with higher IQs are also less likely to cheat and steal.

Young people with lower IQs, though, are more likely to take part in antisocial behaviour, such as harassing or alarming others.

Boys who are antisocial have an average IQ 10 points lower than their more social counterparts.

For antisocial girls, the IQ gap is 5 points lower than their more social peers.

The conclusions come from a study of more than 1,000 young people in the UK.

All were given tests of IQ and externalising behaviour.

For psychologists, externalising behaviour refers to physical aggression, flouting rules, stealing and cheating.

The results showed that fewer externalising behaviours were linked to higher IQ.

In contrast, those with lower IQs were at greater risk of antisocial behaviour.

The study’s authors write:

“Low IQ is a consistent risk factor for emergence and continuity of antisocial behavior across the life course in both prospective and cross-sectional studies, even when other relevant risk factors are statistically controlled.”

Genetic factors are likely important in the link, as well as situational factors, the authors write:

“…cognitive deficits might promote antisocial behavior if children with low IQs misunderstand rules, find it too difficult to negotiate conflict with words, find school frustrating, or become tracked with antisocial peers.”

The study was published in the Journal of Abnormal Psychology (Koenen et al., 2008).

The Bold And Confident Sign That You Have High IQ

The psychologists predicted that intellectual humility would be linked to better results on coursework — but this wasn’t the case.

The psychologists predicted that intellectual humility would be linked to better results on coursework — but this wasn’t the case.

People who are confident in their intellectual abilities tend to have a higher IQ, a study finds.

Those who have confidence bordering on arrogance do better in academic tests.

People with higher IQs tend to agree with statements like “I believe my own ideas are superior to others.”

The intellectually arrogant tend to be seen by others as dominating the group and being extraverted.

Intellectually arrogant people tend to be the centre of attention and also score higher marks in tests, the study found.

On the down side, the intellectually arrogant are not liked as well as their peers who are more humble.

Professor Wade C. Rowatt, study co-author, said:

“One possibility is that people who view themselves as intellectually arrogant know what they know and that translates to increases in academic performance.”

The conclusions come from a study of over 100 students.

The authors thought that intellectual humility would be linked to better results on coursework.

However, it was the intellectually arrogant who got the best scores.

Dr Benjamin R. Meagher, the study’s first author, still thinks humility is a vital trait:

“What I think is important about intellectual humility is its necessity for not only science, but for just learning generally — and that applies to the classroom, a work setting, wherever.

Learning something new requires first acknowledging your own ignorance and being willing to make your ignorance known to others.

People clearly differ in terms of their willingness to do something like that, but that willingness to learn, change one’s mind and value the opinion of others is really needed if people and groups are going to develop and grow.”

The study was published in the Journal of Research in Personality (Meagher et al., 2015).

An Inspirational Sign Of High IQ

This valuable and dynamic ability is linked to higher intelligence.

This valuable and dynamic ability is linked to higher intelligence.

People with above average intelligence are seen as better leaders by others, research finds.

The best IQ score for leading a group is 118.

That is 18 points higher than the average of 100 — making them smarter than around 80 percent of people.

Leaders who are around this much smarter than their followers are seen as the most effective.

However, being too intelligent is linked to worse leadership, the study also found.

It may be that highly intelligent leaders struggle to understand the challenges faced by less gifted workers.

They may also be worse at simplifying jobs and using straightforward language.

In other words, a leader who is too smart may be hard to understand.

The conclusions come from a study of 379 mid level managers working at seven multinationals.

They were rated by their peers, supervisors and subordinates, along with taking IQ and personality tests.

The results revealed that women were generally seen as better leaders, as were slightly older people.

However, the authors explain that these results hold only for mid-level managers:

“Our conclusions are limited too by the fact that the sample consisted of mid level leaders rather than company CEOs who might exhibit far more task-oriented than social-emotional leadership.

We would then expect CEOs to display much higher IQ peaks than those observed here, as well more Conscientiousness and less Agreeableness!

In partial support for this conjecture, recent research suggests that leaders in the top 1% of general intelligence are disproportionately represented among Fortune 500 CEOs.”

Another kink is that the effectiveness of a leader’s intelligence depends on the people they are leading.

More intelligent groups need even more intelligent leaders.

The authors write:

“…Sheldon Cooper, the genius physicist from “The Big Bang Theory” TV series is often portrayed as being detached and distant from normal folk, particularly because of his use of complex language and arguments.

[…] Sheldon could still be a leader—if he can find a group of followers smart enough to appreciate his prose!”

The study was published in the Journal of Applied Psychology (Antonakis et al., 2017).
