A useful technique in this (whether formally double-cruxing or just in trying to get agreement on big group decisions) is to narrow the scope of the disagreement, so you can stay with concrete outcomes of the discussion. Don’t try to resolve whether minimal presentation or high information density is better as a paradigm in general. Do try to resolve, for the anticipated common (and uncommon but important) uses of our product, what range of cognitive expectations we should cater to, and how we can meet the needs of the entire (or at least the demand-weighted bulk of the) audience.
