I was a motivational speaker for a safety conference where one of the other motivational speeches quoted Swiss psychologist, Carl G. Jung.
Jung says a persons source of psycological energy is either predominantly focused outward( extrovert) to your environment or inside, towards yourself (introvert).
The motivational speaker for the safety conference, Brian Dalsy, went on to suggest that there are differences in the brain activity of Introverts versus Extroverts. Extroverts are stimulus hungry. They seek events, people, and experiences outside of themselves to boost their energy levels.
For example, extroverts tend to talk to themselves. As an extrovert, I speak out loud to myself ( when I am alone) all the time; it makes my thoughts external and helps me understand them. An introverts awareness is more focused on their inner thoughts and ideas. They are much less likely to speak to themselves and instead formulate ideas alone before presenting them to the outside world.
The confusion begins when extroverts talk out loud to help them create understanding and formulate ideas. These ideas may change as they speak and evolve to something completely different.
Introverts seek to understand things first and later may chose to talk about them (maybe).
The motivational speaker for the safety conference's motivational speech summed it up by suggested extroverts seek to initiate and bring things to the external environment and introverts seek to figure things out on their own.
Conflict can ensue when an extrovert starts a discussion, working out their ideas which change and evolve as they speak. Meanwhile the introvert is taking the ideas as suggestions or action items and they become jumbled in an incomprehensible mess. ( hmm sounds familiar)
Introverts like time to reflect on their thoughts, extroverts need to discuss them right away to make them concrete.
The myth is that extroverts are outgoing and charismatic and introverts are shy and withdrawn when in reality extroverts seek to initiate and introverts need to reflect. Both introverts and extroverts can be shy or withdrawn in certain situations.
