Biological factors that influence introvert character

There are several chemicals in our brain that affect or influence the way we think and respond. One of the most important neurotransmitters among this is dopamine.

Dopamine is responsible for connecting activities that we do, with feelings of pleasure or reward. Dopamine, the feel-good hormone, plays a significant role in the life of introverts. There is a popular misconception that introverts have a lower level of dopamine in their system compared to extroverts. But that argument is not valid. Introverts and extroverts all have similar levels of dopamine in their system. The difference in the character of introverts and extroverts occurs because of their varied affinity to this neurotransmitter.

Even though everyone has almost similar dopamine levels, introverts are more sensitive to dopamine and is satisfied with a lower level of this substance, any more activities that lead to the production of dopamine creates a sensation of overstimulation in introverts. This is also the reason why introverts don’t often feel excited to the interesting things going on around them, like parties and other social events. Being excited and energetic is a very dopamine-producing process. This is also the reason why introverts in workplaces often try to keep a low profile and avoid challenging responsibilities.
