Funny how everyone who's saying something like this is always sure they belong with the smart ones
For me the biggest problem is discovering/finding (often accidentally) where I need to introspect and/or drill-down.
It doesn't occur to me to examine unexamined assumptions - at all. It's like a blind-spot until one-day: Bam! "You need to go verify this assumption!" (Or conclusion or chain-of-reasoning or theory or whatever)
Out of (say) 5~12 "values" that might matter to most persons - they are in different order, and change the way we process data. To provide a simple example, some people value freedom (autonomy) over safety, and others value safety over autonomy.
So even if people share the same assumptions about how the world works - and they have the same ideology as their tribe - disagreements will still arise.
