This bold and confident sign is linked to higher academic achievement.

People who are very sure of their intellectual abilities are, in fact, smarter than others, research finds.

Intellectual arrogance was linked to achieving higher grades in the study.

People who are intellectually arrogant tend to agree with statements like, “I believe my own ideas are superior to others.”

People are seen as intellectually arrogant by others when they are extraverted and dominate the group, wanting to be the centre of attention.

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.”

For the study, the work of 103 students was followed over a semester.

The results showed that those who felt they were superior to others performed better in their coursework.

However, people who were more humble about their abilities were liked better by their peers.

So, intellectual arrogance may come with a penalty to social relationships.

The study’s authors were surprised by the results: they had predicted that intellectual humility would be linked to better performance.

However, this was not the case.

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).

People with this personality type have higher crystallised intelligence.

Being open to experience is a sign of high intelligence, research reveals.

People who are open to experience are more interested in things that are complex, new and unconventional.

They are sensitive to their feelings, intellectually curious and seekers of variety.

Curiosity and an appreciation of beauty are particularly strong signs of crystallised intelligence, the study found.

Crystallised intelligence roughly equates to general knowledge: knowing many things about the world.

It is natural that people who are curious and interested in new things tend to pick up more general information.

The conclusions come from a study of around 500 people who were given tests of intelligence and personality.

Openness to experience is one of the five major aspects of personality.

Openness also has a number of facets of its own, the study authors explain:

“The Openness to Experience construct involves the tendency to fantasize (Fantasy), aesthetic sensitivity (Aesthetics), awareness of one’s emotions (Feelings), preference for novelty (Actions), intellectual curiosity (Ideas), and preference for non-traditional values (Values).”

The results revealed that more intelligent people were particularly appreciative of beauty: they had a strong aesthetic sense.

They were also likely to be intellectually curious and to have an interest in ideas for their own sake.

These two facets of openness were most strongly linked to higher crystallised intelligence.

The study was published in the Journal of Research in Personality (Ashton et al., 2000).

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?

To access these articles, you need to have a paid membership.

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).
