Donald Rumsfeld was an American politician, businessman, and retired Navy aviator. He served as the 13th and 21st United States Secretary of Defense under Presidents Gerald Ford and George W. Bush, respectively. Rumsfeld was a controversial figure, especially for his famous quote about "known knowns."
What are Known Knowns?
Rumsfeld's quote about "known knowns" came from a press conference in 2002, during the lead-up to the Iraq War. He said, "There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don't know we don't know."
Simply put, "known knowns" are things that we know we know, such as facts and information that are confirmed and verified. They are things that are certain and not subject to debate or interpretation.
Examples of Known Knowns
Examples of "known knowns" include historical events, scientific facts, and basic arithmetic. For instance, we know that the Earth orbits the sun, the boiling point of water is 100 degrees Celsius, and 2+2=4. These facts are widely accepted and not subject to debate or interpretation.
Known Unknowns
"Known unknowns" are things that we know we don't know. These are facts and information that we are aware of, but we don't have the complete picture or understanding of them. They are uncertainties that require further investigation and research to clarify.
Examples of Known Unknowns
Examples of "known unknowns" include the exact number of species on Earth, the extent of human impact on climate change, and the long-term effects of COVID-19 on human health. These are topics that we are aware of, but we don't have all the answers yet.
Unknown Unknowns
"Unknown unknowns" are things that we don't know we don't know. These are the things that catch us off guard and surprise us because we never even considered them as possibilities.
Examples of Unknown Unknowns
Examples of "unknown unknowns" include the discovery of new diseases, natural disasters, and unexpected events in politics, economics, and social issues. These are things that we can't anticipate or prepare for because we never even considered them.
Implications of Known Knowns
The concept of "known knowns" has important implications for decision-making and problem-solving. It means that we should focus on facts and information that are confirmed and verified, rather than speculation or assumptions.
By identifying what we know we know, we can make informed decisions and take actions based on sound reasoning and evidence. This approach can help us avoid mistakes and prevent problems from arising.
Conclusion
Donald Rumsfeld's quote about "known knowns" has become a famous phrase that highlights the importance of focusing on facts and information that are confirmed and verified. By understanding what we know we know, we can make informed decisions and take actions based on sound reasoning and evidence. This approach can help us avoid mistakes and prevent problems from arising.
