more comprehensive personality surveys, done in the last ten years, have actually revealed that introverts are in the statistical majority at 50.7 percent of the populations
The slant toward extroversion in the larger culture has also infiltrated the church. I interviewed dozens of introverted Christians, and without exception, they expressed some degree of frustration and sense of exclusion from their churches. Many have found that their churches, in both theology and practice, are not accommodating to people of their temperament. These introverts have difficulty finding a place in their communities where they feel encouraged to be who they are and to serve in a way that is consistent with their nature.
However, in most evangelical circles, there are three theological anchors-an intimate relationship with God through Jesus, the authority and centrality of the Bible, and active personal evangelism-that are often expressed in strikingly extroverted ways.
Introverts, on the other hand, require less dopamine, and when our brains have too much, we can feel anxious or overwhelmed. Our brains rely more on another neurotransmitter, acetylcholine, a neurotransmitter of the parasympathetic nervous system, which conserves and restores energy, producing a "rest and repose" posture. It produces a pleasurable sensation in introverts when we are thinking and reflecting.
Note: Perhaps this is why I prefer to be alone when I have not had enough sleep, like when I have caffeine, yet when I'm rested, I love social activities.
