Since risk is invariably a matter of future events, there is always some amount of _______________.

The correct answer is that there is always some amount of uncertainty associated with risk because risk fundamentally relates to the potential of future events occurring, which are inherently unpredictable. This uncertainty reflects the lack of complete knowledge about future events, including their nature, likelihood, and potential impacts.

In the context of risk management and the FAIR framework, uncertainty emphasizes the challenge of adequately estimating potential risks and their consequences. Even if one has a wealth of historical data or expert opinions, unknown variables can still influence outcomes. Therefore, managing risk involves not only assessing these variables but also acknowledging and addressing the inherent uncertainty in forecasting future events.

While prediction and probability are important concepts in assessing risk, they do not fully encapsulate the broad range of unknowns inherent in any risk scenario. Instead, uncertainty captures the essence of the unknown aspects of risk, making it the most suitable choice in this context.
