Before you commit

Personality Typology

  • Much of it being shaky science would bother you more than it interests you.
  • You would slide from useful lens into boxing everyone you meet.
  • You want hard answers, not frameworks you have to hold loosely.

Speculative Biology

  • Nobody seeing the years of logic behind one drawing would deflate you.
  • You want a tangible result, not notebooks and tab-stacks of evolutionary logic.
  • Starting a design over because the biology doesn't hold would frustrate you.
