Pretty interesting study!! They found that introverts that used texting to express themselves demonstrated higher levels of self-confidence than those that used texting to escape. However, for extroverts it was the opposite, those that used texting to escape demonstrated higher levels of self-confidence.
As an AuDHD person, aka someone that has made a skipping rope out of the extrovert/introvert line, I have observed that on good days my extroverted side is on outreach mode while my introverted side is on deep connection mode.
That's compatible with information theory. You have a piece of information, the moment you encode it (turn your idea into words) that piece of information is transposed to a little different piece of information, then the channel of transportation adds a bit of noise (depends on the environment, most often literal background noise), and then the receiver decodes the to a different piece of information (turn your words into an idea of their own).
Understanding this concept is an important communication skill. Information theory gives a bunch of tools to minimize the difference between the idea in your head and the perception of the idea by your peer.
