A rhetorical trick to invite others to engage in complex ideas: prepend "I wonder…" to the start of each question or statement.

"I wonder…" makes it about you, not them.

If you ask a question, people feel socially compelled to answer… even if they don't find the question interesting or are intimidated by it.

Saying "I wonder" gives space to the other to engage, but leaves it up to them whether or not to do it.

Because they're under less pressure to reply, if they choose to reply, they'll be more intrinsically engaged, and therefore more open to other ways of thinking.

This approach is an important part of the recipe for nerd clubs.

This trick is especially useful if you outrank someone, since your questions could come across as implicitly intimidating and chill conversation.
