If being introverted worked the way this thread suggests, it would impair function and would be classified as a mental illness or disorder.
There are four types of introverts.
I'm assuming this thread is talking about Anxious introverts and/or maybe social introverts.
I would imagine anxious introverts panic too much to sort of pre script a conversation.
With social introverts, its more of a preference thing. They dont really care enough to do that.
A thinking introvert who is overly analytical and caculating may have a framework for a conversation but only if they have an agenda in play. Its not something they're compelled to do without reason.
With a restrained introvert, it has less to do with their participation than it does the other person. So they're not going to prepare a conversation anymore then anyone else. Its more or less before they just warm up to you.
Oh, and there's hard science behind this as well:
Causes of Introversion
Scientists don't know for sure if there's a cause for introversion or extroversion. What they do know is the brains of the two personality types work a little differently from each other. Researchers have found that introverts have a higher blood flow to their frontal lobe than extroverts do. This part of the brain helps you remember things, solve problems, and plan ahead.
Introvert brains also react differently to dopamine than extrovert brains do. That's a chemical that turns on the reward- and pleasure-seeking part of your brain. Introverts and extroverts have the same amount of the chemical, but extrovert brains get an excited buzz from their reward center. Introverts, on the other hand, tend to just feel run-down by it.
