I've been reading Influence still and a thought about something.

Could gamifying the process of a conversation by getting people to write down their answers to questions be a useful tool for communicating?

According to the book, when people write down answers it triggers wiring for them to remain consistent with something they have put in writin.
Therefore, you could trigger that commitment phenomenon to concepts and ideas, if the questions are calibrated well, and can get individuals to stand by a principle they believe in for instance over a belief they hold.

Example: first question is one of principle where someone defines a principle further for themselves. The second question is calibrated to the first question, but asks a question that is more opinionated or is about a belief (that could be argued).

I am still playing around with this idea but I would like others opinions and ideas on this.
