Expressing and Understanding Estimative Language

Dr Helene Lavoix (MSc PhD Lond) — Mon, 24 Feb 2020 17:21:02 +0000

When dealing with the future, we use a language that includes specific notions such as the expression of probability and of impacts. In terms of probability, for example, we use words such as “likely” and for impacts terms such as “severe”. Furthermore, to be truly complete, we should add a confidence judgement. As explained by …

Scenarios: Improving the Impact of Foresight thanks to Biases

Dr Helene Lavoix (MSc PhD Lond) — Mon, 18 Mar 2019 18:08:23 +0000

Foreseeing the future, whatever the name given to the endeavour, includes two major tasks.

The first one is, of course, the analysis, the process according to which the foresight, forecast, warning, or, more broadly, anticipation is obtained.

The second one is less obvious, or rather so evident that it may be overlooked. It is, however, no less vital than analysis. We need to deliver the output of the analytical process to those who need the foresight, the decision-makers or policy-makers. Ideally, the recipients must understand that output, because they will act on it. They need to integrate the new knowledge received in the decisions they will take.*

A huge challenge runs across these tasks: biases.

We must overcome the various natural and constructed biases – systematic mental errors – that limit human understanding. This article will present first the classical way we deal with biases: we consider them – quite rightly – as “enemies” and we devote much effort to mitigate them. Then, considering the specificity of the delivery stage, this article suggests that another strategy is necessary. We need to turn our usual strategy on its head and befriend biases. In that case, scenarios become a tool of choice for an enhanced delivery of our foresight to decision-makers […]

Modeling for Dynamic Risks and Uncertainties (1) : Mapping Risk and Uncertainty

Dr Helene Lavoix (MSc PhD Lond) — Mon, 05 Nov 2018 09:47:33 +0000

(This article is a fully updated version of the original article published in November 2011 under the title “Creating a Foresight and Warning Model: Mapping a Dynamic Network (I)”). Mapping risk and uncertainty is the second step of a proper process to correctly anticipate and manage risks and uncertainties. This stage starts with building a model, which, once completed, will describe and explain the issue or question at hand, while allowing for anticipation or foresight. In other words, with the end of the first step, you have selected a risk, an uncertainty, or a series of risks and uncertainties, or an issue of concern, with its proper time frame and scope, for example, what are the risks and uncertainties to …

Evaluating Likelihoods for Libya’s Future – Scenario 1

Jon Mitchell (Ma) — Mon, 13 Feb 2017 11:37:01 +0000

Having detailed the various potential scenarios for Libya’s future over the next three to five years, we shall now evaluate the likelihood of the scenarios thanks notably to their indicators. We shall use the methodology developed by The Red (Team) Analysis Society, building upon Heuer (“Assessing Probability of a Scenario”, in Psychology of Intelligence Analysis, …

Useful Rules for Strategic Foresight and Risk Management from Taleb’s The Black Swan

Dr Helene Lavoix (MSc PhD Lond) — Mon, 28 Jan 2013 16:17:01 +0000

This second article on The Black Swan: the impact of the highly improbable by Nassim Nicholas Taleb emphasises some of the author’s points that are crucial for foresight and warning. Likewise, they are necessary for any work dealing with the future and its anticipation, from risk management to horizon scanning through early warning. The methodology of SF&W and risk management allows addressing these points. They should become rules and principles all analysts follow. Indeed, without paying attention to them, good analysis is impossible. The first article on The Black Swan can be accessed here. Humility (Notably pp.190-200) Considering uncertainty, but also our imperfect condition of human beings, the complexity of the social world, feedbacks, our more than insufficient knowledge and understanding, …

Taleb’s Black Swans: The End of Foresight?

Dr Helene Lavoix (MSc PhD Lond) — Mon, 21 Jan 2013 14:42:52 +0000

Since Nassim Nicholas Taleb published his bestseller The Black Swan: the impact of the highly improbable back in 2007, “Black Swans” and “Black Swans events” have become part of everyday language. They are used as a catchphrase to mean two different things. First, as was the case in the Brookings interesting interactive “briefing book” Big Bets and Black Swans: Foreign Policy Challenges for President Obama’s Second Term, “black swans” represent high impact, low probability events, what is also known as wild cards.[i] Second, “black swans” refer to events that could absolutely not be predicted, as, for example for the Economist in ”The prediction games: Our winners and losers from last year’s edition”. Unfortunately, in this case, the label “black swans” excuses foresight …

Modeling for Dynamic Risks and Uncertainties (2) : Mapping a Dynamic Network

Dr Helene Lavoix (MSc PhD Lond) — Sun, 13 Nov 2011 08:45:37 +0000

Go back to Part 1

Actually, any SF&W model as it primarily deals with time should be a dynamic network. How can we expect obtaining any potential outline for the future if our model for understanding is static?

Our map thus aims at representing the potential dynamics of polities. We shall notably use Ertman’s work on past state-building, but making it adaptable to present and future conditions.
