HILP Concept

Black Swans, coined by Nassim Nicholas Taleb in his book “The Black Swan: The Impact of the Highly Improbable” is a concept within the broader context of risk management, that represents unpredictable and rare events with significant consequences. In the realm of rare and impactful occurrences, Black Swans represent instances where unpredictability reaches an extreme level, resulting in extraordinary and often unprecedented impacts.

In the context of High Impact Low Probability (HILP) events, Black Swans stand as the giants of unpredictability, reshaping landscapes and challenging assumptions. Black Swans exemplify the severity of HILP events and are characterized by their unpredictability, high impact, and retrospective predictability. While challenging to foresee, these events have profound and lasting consequences. Investigating HILP events involves recognizing the role of Black Swans and preparing for uncertainty.

Example:
The global financial crisis of 2008 is often considered a Black Swan event. The magnitude and widespread impact of the crisis, fueled by complex financial instruments and systemic failures, caught many by surprise.

Dragon Kings, a concept created by physicist Didier Sornette in his 2009 paper “Dragon-Kings, Black Swans and the Prediction of Crises”, characterize outliers in statistical distributions that have a disproportionately large impact compared to other extreme events. These outliers deviate significantly from the expected behaviour predicted by traditional statistical models. The name “Dragon Kings” itself is metaphorical, drawing an analogy between these extreme events and mythical creatures like dragons that stand out in size and impact.

Dragon Kings, within the realm of HILP events, symbolize extreme outliers that demand attention due to their potential to cause massive impacts. They serve as a crucial aspect of understanding HILP events, showcasing instances where the combination of low probability and substantial impact becomes pronounced.

Example:
The Fukushima Daiichi nuclear disaster in 2011 serves as an example of a Dragon King event. While the occurrence of nuclear accidents is rare, the Fukushima disaster had a colossal impact, not only in Japan but globally.

Grey Rhino, a metaphor formulated by Michele Wucker in his book “The Gray Rhino: How to Recognize and Act on the Obvious Dangers We Ignore”, represents highly probable and high impact events that are often neglected or ignored, even though they are easily anticipated and addressed. In contrast to “Black Swan,” which represents unpredictable, rare, and extreme events, “Gray Rhino” emphasizes the need for proactive and strategic thinking in the face of more foreseeable challenges.

Grey Rhino events within HILP scenarios  are risks that, if addressed, can mitigate severe impacts. Understanding HILP events requires acknowledging and mitigating Grey Rhinos.

Grey Rhinos are integral to the understanding of HILP events, showcasing instances where known risks, despite being predictable, can lead to significant consequences if not addressed. In other words, they are characterized by their visibility and predictability, yet societal tendencies to overlook them. In the broader analysis of HILP events, recognizing and proactively managing Grey Rhinos is paramount.

Example:
The 2008 housing market crash in the United States is a classic example of a Grey Rhino event. The risks associated with subprime mortgages were visible, yet they were often ignored or underestimated. The predictable dangers led to a severe economic downturn, emphasizing the importance of addressing known but neglected risks.

Perfect Storm represents a rare convergence of multiple risks/events, creating a situation with unusually powerful or critical outcomes. It underscores the importance of recognizing and understanding the potential impacts of combined interacting forces in complex systems. The phrase originates from the idea that a storm becomes exceptionally intense when various weather elements coincide.

In HILP scenarios, it symbolizes the scenario where various risks merge, creating a formidable challenge and it adds a layer of complexity to the understanding of HILP events. It highlights the significance of preparing for scenarios where risks converge, requiring strategic planning and adaptability.

Example:
The 2005 Hurricane Katrina and its aftermath serve as an example of a Perfect Storm event. The convergence of natural disasters, inadequate infrastructure, and delayed response created a catastrophic situation with severe and lasting consequences.

Gray Swans, a concept within the broader context of risk management, represents events that fall between the known (White Swans) and unexpected (Black Swans). In the context of HILP events, Gray Swans are those occurrences that are somewhat predictable but not widely anticipated. These occurrences may not be entirely unexpected, but they possess elements of surprise.

Example:
The Y2K (Year 2000) computer bug scare is considered a Gray Swan event. While there was widespread awareness and preparation for potential computer glitches at the turn of the millennium, the actual impact was not as severe as anticipated. It exemplifies an event that was somewhat predictable but did not result in the expected high impact.
