knightian uncertainty is a kind of uncertainty that is

Abstract. Jason Tugman is a Cyber Risk & Strategy consultant for Critical Infrastructure with a focus on Finance and Energy. Before you throw the room-tying-together-rug out with the pee stain, there’s yet another character to introduce from days gone by that can provide us with some hopeful guidance. Knightian uncertainty speaks to the unknown unknowns — the knowledge you don’t have and the risks you don’t see. Then that model is identified which, if true, would result in a worse outcome than any other model in the family. Accepting this as true (which it is), also renders “Ummm, nothing” completely inadequate. At the heart of uncertainty is ignorance. The process of risk management and management forces us to think through our objectives, what the risks are, and how we can reduce risk. The appeal of this technique is that it provides insurance against the worst anticipated outcome. Knightian uncertainty (ambiguity) implies presence of uninsurable risks. 2 This paper applies the idea of the Knightian uncertainty to the job search model, and compare the effect of its increase on the worker’s search behavior with that of an increase in risk. = \roulette" Opinions in subjective logic [5] carry this type of uncertainty. What is in store is invisible. This is not possible under Knightian uncertainty because one lacks knowledge of the underlying distributions. Some scholars also define Knightian uncertainty as the inability to imagine all possible outcomes (e.g., Alvarez, Afuah, & Gibson, 2018), but this view is less common among economists. However, probabilities are measures of frequencies of events that have happened in the past, and therefore, in real-time we are not necessarily confident that they represent accurate descriptions of the future. Simply understanding the logical path may be enough to identify a critical vulnerability. Risks around those most likely occurrences are described probabilistically, and confidence in one’s actions in turn is best captured with statistical intervals. Yes, exactly! The purpose is not only to simply deepen our conceptual knowledge, but to, and this is particularly relevant to Austrianism, identify and examine the potential of going beyond the mere and rigid dichotomy of risk vs. uncertainty which Knight and Ludwig von Mises rely on. There need to be a distinction between probs which are there and those which are not. Maybe there’s a trade off between efficiency and flexibility that is important, especially when the situation is volatile. Very informative and relevant in the present scenario. While we are inherently used to dealing with risk in our economic activities, few are prepared for total unpredictability. As we accept Knightian uncertainty, and the vampire fallacy, and maybe even a little nihilism, we cannot confidently (or truthfully) say to our executives that we are prepared for the next big event; the stochastic and nonisomorphic make for too much uncertainty. It is the hardest to deal with because you can’t address it directly. If we accept Knightian thinking then we accept that we cannot know the next shockingly-stock-dropping-event that befalls our beloved organizations. In his book, Knight differentiated between risk, potential events that can be measured, and uncertainty, the unpredictable. This second kind of uncertainty, an uncertainty without delimiting parameters, has come to be known as "Knightian uncertainty," and is commonly distinguished in economics from quantifiable certainty, which, as Knight noted, is more accurately termed "risk." Why didn’t he just leave it at knowns and unknowns; why bother including the ridicule inducing unknown unknowns? This is not possible under Knightian uncertainty because one lacks knowledge of the underlying distributions. A state of uncertainty where some possible outcomes have an undesired effect or significant loss. History provides us with enough example that proves every few years we have events that defy established models and conventions. Risk A state of uncertainty where some possible outcomes have an undesired effect or significant loss. However, we know the logical assets that provide critical functionality to our most important business capabilities. So, what should our next conference room cornering response be? Do we have a risk transfer capability (such as insurance) that covers this type of disruption? ( Log Out /  ( Log Out /  A claim dominates quasi{surely another claim if it REVISED PROOF 12 RESEARCH PAPER 3 Knightian Uncertainty Meets Ranking Theory 4 Wolfgang Spohn1 5 Received: 15 March 2017/Accepted: 28 July 2017 6 Springer International Publishing AG, part of Springer Nature 2017 7 Abstract Knightian uncertainty is not a special kind of uncertainty; it’s just 8 uncertainty. Should Cyber Risk Likelihood Be Quantified? Knightian uncertainty is evidence that people believe — often unjustly — that some frames are more certain than others. Knightian uncertainty involves a situation that has unknown probabilities. Change ), You are commenting using your Twitter account. We have run through scenarios and white-boarded potential threat vectors and we have identified both our existing controls and our control gaps for those threat vectors. This write up was very informative. Knight by contrast emphasises that they cannot be measured! There are few papers on the uncertainty. And it raises the issue how we may model uncertainty. As we will discover, this piece of Rumsfeldian wisdom has quite a bit to do with cyber risk, risk quantification, and organizational risk strategy. For this reason, the crisis has cast new attention on an idea about risk from decades past: "Knightian uncertainty." Knightian Uncertainty Critique of the Probabilistic Model Frank Knight: Risk, Uncertainty, and Pro t Risk = \Roulette" = objective probabilities Uncertainty = \Horse Races" = no probabilities many entrepreneurial decisions are \horse{races" (start{up) nancial markets: well-known assets, options, mortality risk, car insurance etc. Institutional quality may be a good indicator of Knightian uncertainty. The concept acknowledges some fundamental degree of ignorance, a limit to knowledge, and an essential unpredictability of future events. Decision making under risk relies on known probability distributions of outcomes. Let us take Knightian and Keynesian uncertainty, respectively, to mean the type of uncertainty about which Knight and Keynes wrote, particularly when using the term ‘uncertainty’ or ‘uncertain’. For readers clinging to the notion of maintaining a proactive state, I have two more questions: “There is no way of knowing that!” you say? What is the physical or logical path that would enable a disruption i.e., how would the disruption happen? Gilboa and Schmeidler (1989)’s ambiguity averse agents use a maxmin crite- These are unknown events, with unknown vectors. If we accept that true uncertainty is the lack of knowledge, then we must accept that the identification and understanding of the logical piece-parts that make up our environment is a crucial first step in separating the knowable-unknowns from the truly uncertain. The concept of Knightian uncertainty has played a facilitating role in the development of both strategy and entrepreneurship research, but one that has vacillated in its relevance and interpretation. If it is possible to assign a probability but we do not know it we have ambiguity, if it is not possible to assign a probability (end hence it cannot be measured) then we face uncertainty. Knightian uncertainty isn't a separate discrete category, it's an endpoint of a particular interval on the other end of which sits uncertainty that you know everything about, e.g. A second kind of uncertainty, captured by Rumsfeld’s distinction between known unknowns and unknown unknowns, is that relating to a person’s ignorance of their own gaps in knowledge: (2) Uncertainty concerning the existence of unknown unknowns, where a person is unaware of some gap in knowledge. Change ). However, from a Knightian perspective, uncertainty precludes analogy because such situations are unique. This is too big a problem to solve. Recall that the phrase “black swan” gained currency a decade ago during the Great Recession and aftermath. We don’t know its mode, its vector, nor its asset or data target(s). Start big-picture and then drill down. A family of possible models are considered, without assigning probabilities to their occurrence. But remember, identifying much less eliminating true uncertainty is too big a problem to solve. • The value reduction caused by Knightian uncertainty is much more substantial for the value of … What was he talking about when he said that there are knowns and unknowns, but that there are also unknown unknowns? The insight of John F. Muth that expectations should be model consistent has great attraction. Coined by economist Frank Knight in 1921, Knightian uncertainty refers to a total lack of quantifiable knowledge about a possible occurrence. It may be wise to achieve more flexibility in times like these, even if it may be at the cost of little more efficiency. ( Log Out /  In addition to interviewing H.R. For those seeking that mystical magic bullet, that solve-every-problem rack-and-pray piece of AI technology, General McMaster has appropriately coined the term “vampire fallacy,” the belief that technology can eliminate risk in warfare and make it fast and cheap. Change ), You are commenting using your Twitter account. We need to be patient and cooperate with the government decisions at this moment until a vaccine is found and the disease is controlled. The concept acknowledges some fundamental degree of ignorance, a limit to knowledge, and an essential unpredictability of future events. Who knows what you will find! This second kind of uncertainty, an uncertainty without delimiting parameters, has come to be known as "Knightian uncertainty," and is commonly distinguished in economics from quantifiable certainty, which, as Knight noted, is more accurately termed "risk." In 2002 Donald Rumsfeld made his now-infamous statement of “Unknown unknowns”. Uncertainty, on the other hand, applies to situations where we cannot know all the information we need in order to set accurate odds in the first place. The planner starts with a number of models that may be relevant, but cannot identify the likelihood with which they describe the situation. If an increase in “uncertainty” is an increase in the variance of the wage offer distribution Ontological uncertainty refers to a situation where the nature of an event and its associated probability to happen are not known. As Knight saw it, an ever-changing world brings new opportunities for businesses to make profits, but also means we have … What are the critical functions of the project, program, product, or company? Nothing. In How to Solve It, Polya simply states that “If there is a problem too big to solve, there is a smaller problem you can solve; find it.”. The “Ummmm, nothing!” response to the corporate conference room cornering is starting to seem reasonable! The second one is another kind of uncertainty, which deserves the name of true fundamental uncertainty. In the real world, all events are so complex that forecasting is always a matter of grappling with “true uncertainty,” not risk; past data used to forecast risk may not reflect current conditions, anyway. uncertainty have on R&D investment and innovation. If Frank Knight is arguably the most famous economist few have heard of, it is because of Knightian uncertainty which established a major idea and reputation in the discipline of economics, but was not the beginning of other pioneering work, as he turned to teaching and essay-writing as a critic of other ideas and thinkers that were to remain more famous than himself. The lesson that the 2007 financial crisis has taught us is that even though models do serve us satisfactorily most of the time, there will be times that they fail us, and they may even fail us spectacularly. Under risk, we are confident — at least probabilistically — of the underlying model or combination of models that describe the scenario. The concept acknowledges some fundamental degree of ignorance, a limit to knowledge, and an essential unpredictability of future events. Not only are It was in the late 1970s in a high school in the suburbs of Stuttgart, Germany, during an event organized by some of the young teachers of the new school that a group of scared and politicized pupils had a discussion with the scientists who defended nuclear energy and the building of nuclear plants.

Ontological uncertainty refers to a situation where the nature of an event and its associated probability to happen are not known. But what if I were to say that “Ummm, nothing” is the appropriate response? We discussed Knightian uncertainty at considerable length, … In the case of COVID-19, the models used are based on several dangerous global outbreaks from the past two decades: SARS in 2004, H1N1 in 2009, the Ebola outbreak in 2015, and even the Spanish flu in 1918. True uncertainty is found in those stochastic and nonisomorphic events–those events we think we know but just ain’t so–that take an organization by surprise; asymmetric to cyber strategy. Readers of this site or anyone who has seen me speak at cyber conferences—or has spent more than 15 minutes with me at a bar over a gin—will have heard me spout about the greatest cyber risk management book I have ever read. Search and Knightian uncertainty Kiyohiko G. Nishimura a, Hiroyuki Ozaki b, ... the answer is drastically different depending on what kind of “uncertainty” is involved. The “optimal” course of action is one that restricts the choice of actions available and depends on a small set of simple rules and heuristics. World Health Organisation (WHO) and Governments regarded their own apparently precise risk assessments as trustworthy may have thought they were operating in conditions of Knightian risk, where they could judge the odds of future outcomes. We don’t know if patching will prevent it (assuming a patch is released in time), or even if our organization will be directly susceptible or if it will wreak havoc on one or more of our critical vendors. It was introduced by Frank Knight, a University of Chicago economist, in the 1920s. This paper correlates non-life insurance penetration in 70 countries with income level, financial sector depth, country risk, a measure of cost of insurance, and the World Bank governance indexes. For some reason, I’ve come across an idea called “Knightian Uncertainty” quite a bit lately. It is no surprise that executives and board members seek assurance against falling prey to such events. What standards (frameworks, models, regulations, best practices…) leave out is the need to identify not only the functions and their assets but the threat vectors associated with those assets. The meaning of Knightian uncertainty is that the future may differ substantially from the past. tainty aversion or the degree of Knightian uncertainty. This is true uncertainty. Innovations, social and political change, historical events, etc., can make the past a weak indicator of the future. Thank you, Arvind. What does a bad day look like and how would it happen. This is not to say that zero-day events are the sole concerning uncertainty, only that they serve as an immediate interest and are well suited for this discussion. If one were to give an honest answer to what proactive steps are being taken to prevent the next big event, one would simply shrug and say “Ummm, nothing”. The world has been devising and finding new techniques to deal […]. Recently, I found myself in a conversation with someone advocating the use of Knightian uncertainty. Please answer the following questions: Dollars to donuts the answer to question 2 is yes; typically, what organizations do to “prepare” for the next event is to mitigate the vulnerability of the last event. In economics, Knightian uncertainty is a lack of any quantifiable knowledge about some possible occurrence, as opposed to the presence of quantifiable risk. He also claimed preferences that depend upon his Knightian uncertainty and that he's not an expected utility maximizer. For this reason, the crisis has cast new attention on an idea about risk from decades past: “Knightian uncertainty.” Frank Knight was an idiosyncratic economist who formalized a distinction between risk and uncertainty in his 1921 book, Risk, Uncertainty, and Profit. Henceforth I use the term "uncertainty" (or "ambiguity") in the sense of Knight (1921), who first defined risk and uncertainty independently. Change ).
