Very useful. I have a thing for a good definition or clarification.
EDIT: so how would you define the manifestation of the second instinct? Is it merely based on priority or does the first frame the second? If I'm So/Sp, does that mean (basically) I tend to notice trends and then look at how we should address them (which is pretty accurate IMO)? You're Sx/So, therefore you focus on mental/physical/spiritual/emotional stimulation and how it varies from context to context? OK, that doesn't sound quite right, but is it something along those lines?
