This is part of a series of occasional “synthesis blog posts” drawing together perspectives on related topics across i2Insights contributions.

How can different disciplines and practitioners enhance the ability to understand and manage unknown unknowns, also referred to as deep uncertainty?

Seventeen blog posts have addressed these issues, covering:

  • how unknown unknowns can be understood
  • exploiting unknown unknowns
  • accepting unknown unknowns
  • reducing unknown unknowns.
