Which term best matches the description Things we don't know that we don't know?

• A. Unknown Unknowns
• B. Hard Evidence
• C. Substantial Evidence
• D. Guesses

Answer: (A)

The idea being tested is how we categorize gaps in our knowledge based on what we recognize as unknown. The phrase that best fits "things we don’t know that we don’t know" is unknown unknowns. It refers to those areas where we aren’t aware that there’s something to learn or a possibility we haven’t even imagined, so they can surprise us and catch us off guard. This concept is especially important in planning and risk assessment because it reminds us to build flexible systems, seek diverse information, and expect surprises rather than assuming we’ve already accounted for everything. Hard evidence and substantial evidence talk about how much information supports a claim, not about our awareness of gaps in knowledge. Guesses describe stabs at an answer, often with some rationale, but they don’t speak to a lack of awareness about unknowns.
