It is important for a modern person to accumulate a wealth of knowledge. One should also be able to use it in order to always be able to solve emerging problems.
Everyone learns, applies in practice what he has learned. An individual may think that he has surpassed many in development, which is not always the case.
One can speak of the presence of above average intelligence if certain signs are present.
Sarcasm is clear
To understand it, you need to use abstract and creative types of thinking. They are well developed in those with high intelligence.
Such a person can distinguish between the real and literal meaning of what is being said and understand the essence of a sarcastic phrase.
Knowledge of a foreign language
And even several. Learning languages develops the brain, their use allows to increase intelligence.

The eldest child in the family
There are observations and studies that show that the level of intelligence of several children in a family is higher in the eldest than in the others.
It is not genetics that influences this, but the fact that for some time the first child is the only one for the mother and father. They devote all their attention and time to his development.
Left hand dominant
Left-handers, of whom only 10% are in the world, have better developed cognitive functions than right-handers.
This can explain why their intelligence is higher. This is not observed in all cases, but there are many such examples.
Doubts about intelligence
An intelligent person has the idea that he still has a lot to learn.
He does not consider himself perfect, admits mistakes. This allows him to become even better, to raise his intellectual level.
