Abstract
Humans have an amazing capacity to imagine the future, and most foresight tools use this capacity but don’t explicitly support it. The Horizons Foresight Method puts this power to model and visualize at the center of the foresight process. This paper introduces foresight and scanning in general terms, describes how we can support the “inner game” of foresight, outlines the steps in the Horizons Foresight Method and some of the practical issues that arise when using it. There are many tools in the futurist’s toolbox and many good foresight methods. At Policy Horizons Canada, we use a variety of methods depending on the purpose of each foresight study. The Horizons Foresight Method is a strategic foresight method that was designed to help government policy analysts and decision-makers explore how complex systems could evolve and to address the kinds of policy relevant uncertainty these shifts generate. It provides a

To be clear, the Horizons Foresight Method is designed to support strategic foresight. That is, to help policy analysts and decision-makers to explore the range of plausible futures and challenges and opportunities that lie ahead. It can be used to develop robust strategies. See Figure 1.

The Inner Game of Foresight
One of the unique features of the Horizons Foresight Method is that it deliberately harnesses our natural mental capacity to model the future. We can recall “pictures” in our minds and replay “movies” from our past experience. We can also create and manipulate pictures and models of completely new ideas in our minds. For instance, humans use this capacity when we weigh pros and cons in our head or when we run “movies” to explore a difficult decision. Indeed, we practice an embryonic version of foresight using tools like extrapolation, impact assessment and scenarios on simple problems in our minds. We often experience this mental modeling as a verbal process—as questions, statements, and stories in words in our head. But if you observe your own mind closely, you will often find there is an underlying visual process.
Over the years, many foresight practitioners (e.g., Senge 1999; Wack 1972) have talked about the central role of mental models in foresight but have not explicitly brought them into the process. The Horizons Foresight Method works directly with participants’ mental models to strengthen and take advantage of this inner game of foresight in the following ways:
the mind constructs small-scale models of reality that it uses to anticipate events, to reason, and to underlie explanation . . . Mental models have a structure that corresponds to the structure of what they represent. They are akin to architects’ models of buildings, to molecular biologists’ models of complex molecules, and to physicists’ diagrams of particle interactions . . . Everyday reasoning depends on the simulation of events in mental models.

According to this theory, the four building blocks in mental models are facts, assumptions, experience, and dialogue. Of necessity, mental models are incomplete representations of reality, and sometimes they are wrong. Policy analysts, managers, and leaders usually have well-developed mental models of the systems they manage. They use these models to run movies in their heads of how a given action could play out within the system so they can test ideas, develop strategies, and make decisions. There are a number of reasons for working directly with people’s mental models. Examining mental models helps us understand how people think a system works. We can combine models from different people’s perspectives to get a more complete picture of the system. With a deeper understanding, we can identify and test the underlying assumptions that shape decisions. While most participants are unaware of this aspect of their mental lives, they are happy to work with it.
Surprises coming from the places we are not looking—scanning can help. The cascading (third, fourth, and fifth order) impacts of change as it rolls across the system—cascade diagrams provide the scaffolding to see how change evolves over time. Changes interacting with each other at the same time—cross-impact analysis is useful. Lack of awareness of the pathways through which change could flow—system mapping can help. Lack of imagination as to how unexpected patterns of change could emerge—scenarios embodying different models of change can help. Looking at each of these sources of surprise in a systematic way provides useful information to reduce uncertainty and understand how the system could behave and evolve.

The Steps in the Horizons Foresight Method
This process is fluid, dynamic, and iterative. Each step builds a better understanding of the system, how it could evolve and what surprises could emerge. At each step, a large amount of information is gathered, considered, filtered, and then edited to focus attention on the essential building blocks. Simple diagrams and other visual tools provide scaffolding to enable participants to share their models and facilitate dialogue at every step in the process. In Figure 4, the method is presented as a linear process, but in practice it is common to move back and forth among the steps as understanding of the system grows.

What Are the Results of the Horizons Foresight Method?
Who Should Be Involved?
There is value in engaging stakeholders and many others in this kind of process. One of the big challenges with engaging outsiders is they tend to focus on what they know (the expected future) and what they want (their interests). Useful foresight requires that they be aware and ideally knowledgeable about the possible disruptive forces that lie ahead—weak signals and trends that could disrupt the system. If these disruptive forces are ignored or misunderstood, you may be wasting your time. But, in short workshops, it is difficult to do. It takes hours and sometimes days to have a basic understanding of a potential driver like artificial intelligence or blockchain.
One of the ways to solve this dilemma is to run parallel processes. When Horizons uses this method to conduct a foresight study, there is a core team who act as caretakers of the process. They are aware of the tools, concepts, and what can usefully be achieved in foresight. They do the study and systematically seek input from others. In a major study, hundreds of thoughtful people are interviewed during the scanning phase to surface their mental models of the system, in order to understand how different parts of it work and how it could evolve. Then, one or more groups of external participants and stakeholders are invited to do a short, customized version of the process to benefit from their knowledge and the collective interaction of their mental models as input to the study. Given the pressures to digest a huge amount of information about the whole system and potential disruptive changes, the external participants can seldom commit the time needed for an entire study, so the core team does most of the work. The short workshops help the core team understand the system, fill in gaps, and explore new and identify missing viewpoints.
The knowledge and personal qualities of the team, interviewees and participants can make a huge difference in the success or failure of a foresight study. The following personal qualities can be used to screen potential participants and improve the chances of success:
Participants and stakeholders are knowledgeable about one or more parts of the system and represent diverse views or interests.
They have good group skills.
They are curious and open to other views and learning new things.
They are creative and comfortable with thinking outside the box.
They have a high tolerance for ambiguity and uncertainty, as it takes time for a group to bring the pieces of the puzzle together.
How Long Does It Take to Do a Study?
Once the core team understands the Horizons Foresight Method, a foresight study on a complex public policy issue can take two to twelve months, where half of that time is spent scanning and conducting interviews to identify potential disruptive changes. In parallel, if a dry run is being done with external participants, it is possible to go through all of the steps with them in two or three days—often spread over a week or two to give participants time to digest and reflect on what people are saying.
How Do You Get Buy-In From Those Who Are Not Involved?
In foresight projects, it is common for the people who are directly involved in the study to be fully committed, but non-participants can be resistant to the results. Horizons uses several ways to engage non-participants in the process. Interviewing senior people to collect their understanding of the system is a useful way to involve them if their time is limited. Often they will be interested in the report, because they want to see what you did with their insights. After the study is complete, Horizons designs exercises for groups to immerse them in the study and to surface and test their mental models. Generally, the best way to communicate the written report is to take the reader through the process in a way that allows them to construct their own mental model and see the future for themselves.
Conclusion
There are many useful approaches to foresight. The Horizons Foresight Method has been designed to address the kinds of uncertainty and complexity that arise in public policy settings. At each stage in a structured process, the Horizons Foresight Method provides scaffolding to help individuals surface and share their own mental models and to construct a collective model of the system and how it could evolve. What is unique about the Horizons Foresight Method is the emphasis on utilizing the amazing capacity of our minds to visualize and run simulations at every step in the foresight process. Most participants report they feel better prepared to deal with a rapidly changing policy environment.
The Horizons Foresight Method focuses on the essential steps to help individuals and groups do useful and strategic foresight. The main results (robust assumptions, plausible futures and emerging challenges and opportunities) have enormous value in forward-looking policy and planning processes.
