I have found that very well-educated, very articulate people often speak with a tone of condescension or with a vocabulary that annoys those who hear them.
True story: I used to sell instructional technology to educators. My manager told me one day to lower the cognitive level of what I said to people in that job - that educators tend to feel threatened by those who use words they don’t understand. Likewise, I have found that many average Joe/Jane members are turned off NOT because someone is a scholar, but rather because that person can’t or doesn’t speak their language - because the tone sounds condescending or the statements can’t be understood. There is BIG difference, and it's critical that those who are trying to share concepts that are new to people in the Church recognize that difference.
