Intelligent people are often very unique. Their uniqueness stems likely from their principles and motives which in turn stem from their past experiences – whether pleasant or unpleasant. Moreover, they become unique because they can’t naturally exhibit or emulate the typical behavior of the average person.
Good at humor or interpreting humor:
I just read somewhere that humor is an elementary cognitive function. Developing and interpreting humor requires a good level of cognitive ability. Someone with a high level of cognition may even laugh at something which apparently wouldn’t be funny just because that individual is capable of relating what he’s perceiving with something he knows. This relationship the individual builds in the mind results in humor. You may relate to a bottle of wine with an incident of your friend throwing up drunk.
Anxiety or some mental disorder:
Anxiety is a good indicator of intelligence. Yep! Thank your anxiety because this ‘fear of the future’ comes off your ability to process current events and come up with a plausible extrapolation of what could happen next. This could also be a by-product of overthinking which again involves developing possible explanations (hypothesizing) based on known information or assumptions. People with a low level of anxiety when tasked with something new likely lack intelligence but hey – I’m not throwing off theories! This is my opinion of how anxiety may be correlated with intelligence. Mania can also be another mental disorder associated with intelligence. This ability of a person to rapidly process stimulus and thoughts may backfire when not desired leading to this condition.
I personally get very irritated by petty things when I’m already frustrated. The trend from there is exponential – much like a runaway! I get annoyed by the wind and also believe me – cursed the weather for being ‘drunk AF’. I personally believe that the tendency to become easily irritated by some external stimuli or thought indicates the extent to which a person expects structure or order. The reason why one expects structure in the world around them would come down to how a person’s brain is wired – such as a brain wired for performing the scientific method (a systematic approach of doing science). This brain would crave logic and consistency with it’s thoughts (assumptions) and any anomaly in it’s word may be deemed as annoying. A gust of wind from an odd direction may be annoying as it wasn’t expected and ruined the brain’s expectation of how it (wind) should ideally behave.
This is purely my personal opinion. I believe verbal intelligence such as the ability to use appropriate vocabulary, synonyms interchangeably or appropriately, implementing parallelism in sentences may be correlated with intelligence. Furthermore, processing words (talking or writing) at a high rate could also sum all of our above ideas. I say this because processing words as a whole requires you to rapidly look up vocab from your memory, process simultaneous streams of information and retain them so you can go back and re-think them.
Lastly, I blame spontaneity for my inability to concentrate. I believe this to be a by-product of the ability of the individual to process information rapidly – allowing them to come up with the most fascinating of ideas in the most random of situations. These situations sometimes may deem that idea or activity inappropriate making the individual crave for it. This leads to distractions as the mind actively anticipates when it possibly may get to perform it.
When the brain is capable of optimizing something it wants to do in the near future in a way it allows for it to be performed in a shorter time – the brain comfortably procrastinates. Also, laziness may be the result of one’s personality. Some traits may include appreciation of what’s around them (because they know so much about them) and a lack of urgency about performing the anticipated activity (because they know how to optimize it and make it more rewarding when it’s performed i.e., find shortcuts).
There are lots of other personality traits and quirks in smart people but these are the best that would come to my mind.
