Does this sound like the set of challenges you might be facing?

  • In my head the things I’m sure of and the things I’m just guessing at all run together as one blur, so I end up treating my assumptions like hard limits
  • My conclusion only makes sense because of a bunch of things I’m silently taking for granted about people and how the world works
  • My plan feels solid until I notice it quietly depends on a whole stack of things just going my way
  • "She was being dismissive" feels like a plain fact to me, exactly as solid as "she left the meeting early"
  • My beliefs are all hedged into mush
