The concept of unknown unknowns highlights the importance of introspection in assessing knowledge. It suggests that finding our way in the set of known-knowns, known-unknowns, unknown-knowns and unknown-unknowns, reduces to asking:
- how uncertain are we? and
- how aware are we of uncertainty?
When a problem involves a decision-making team, rather than a single individual, we also need to ask:
- how do context and perception affect what we know?
