Speculative design is a critical design practice that uses imagination, research, and prototyping to explore alternative futures and challenge the assumptions embedded in the systems we build today. Rather than solving an existing problem, it asks “what if?” – and designs from the answer. The goal isn’t a polished product, but a provocative experience that challenges people to question the future they are designing toward.
In this guide, we cover every important aspect of speculative design, from its principles, methods, and processes to its applications across industries. Whether you are a designer or a product strategist, this guide provides everything you need to understand and apply speculative design in your own context.
What is Speculative Design?
Speculative design is a design practice that treats the future as material. Instead of designing for users as they exist today, speculative designers build artifacts, scenarios, films, and experiences that embody a possible or deliberately impossible future, and use those objects to provoke critical conversation about the direction society is heading.
The practice was formally articulated by designers and educators Anthony Dunne and Fiona Raby, who developed it at the Royal College of Art in London through the 1990s and 2000s. Their 2013 book Speculative Everything: Design, Social Dreaming and Futurism became the field’s defining text, arguing that design could function as “a means of speculating about how things could be” rather than simply how things are.
Speculative design does not predict the future. It does not offer solutions. What it does is open up the space of possibility by showing:
- That the future is not fixed
- That the choices being made today in technology, governance, and industry have consequences
- That those consequences are worth examining before they arrive
A strong example is the Black Mirror episode “Nosedive,” which imagines a world where social interactions are publicly rated, directly influencing socio-economic status. Much like asset price bubbles or speculative investments in the forex market, the episode illustrates how systems built on perception can collapse under pressure, exposing the market volatility of human value in a digital age. This speculative scenario pushes viewers to confront the ethical implications of technology-driven social structures.
How Speculative Design Differs from Traditional Product Design
Traditional product design begins with a problem and ends with a solution. It is commercially oriented, user-centred in a utilitarian sense, and measured by adoption and market performance. Speculative design, by contrast, begins with a question and ends with more questions. Its success is measured by the quality and durability of the conversation it generates, not by the number of units sold or screens visited.
Speculative Design vs. Design Fiction vs. Critical Design
These three terms are closely related, but they are not the same.
Speculative Design
Speculative design is the broadest concept. It uses ideas, scenarios, and designed experiences to explore possible futures and spark discussions about what the future could or should look like. It is more of a mindset and design approach than a specific format.
Design Fiction
Design fiction uses storytelling to make future ideas feel real and believable. It places designed objects or interfaces inside fictional future worlds, such as a product advertisement from 2045, a future app UI, or a manual for a technology that does not exist yet. The goal is to help people imagine how future technologies could affect everyday life.
Critical Design
Critical design is more focused on questioning current systems, behaviors, and values. Instead of solving problems, it challenges assumptions behind modern products and technologies. Critical design concepts may intentionally feel uncomfortable, impractical, or provocative to encourage deeper reflection and debate.
A Brief History of Speculative Design: From Dunne & Raby to Today
Speculative design emerged from the Radical Design movement of the 1960s and 1970s, where designers challenged mainstream ideas through provocative concepts and imagined futures. Thinkers like Victor Papanek also pushed designers to consider the ethical and social impact of their work.
The field was later shaped by Anthony Dunne and Fiona Raby at the Royal College of Art, who formalized ideas around Critical and Speculative Design through influential projects and writings in the late 1990s and 2000s.
By the 2010s, studios like Superflux and Near Future Laboratory expanded speculative design into areas like policy, technology, media, and business innovation. Today, it is widely taught and used by universities, consultancies, NGOs, and innovation teams around the world.
Core Principles of Speculative Design
Speculative design is governed by a set of core principles that distinguish it from adjacent creative and research practices. Understanding these principles is essential before beginning any speculative design project, because they define what makes the work speculative rather than simply imaginative or futuristic.
1. Prioritizing “What If” Over “What Is”
The foundational move of speculative design is to shift from the descriptive to the hypothetical. Rather than understanding and improving what currently exists, speculative designers begin by positing a changed condition, say a new technology, a different social norm, a reversed political reality. And then ask – if this were true, what would the designed world look like? This “what if” orientation liberates the designer from the tyranny of feasibility and opens up the full space of possibility.
2. Provocation as a Design Outcome
In speculative design, provoking thought, conversation, and debate is a legitimate and complete design outcome. The work does not need to resolve into a product, a policy, or a recommendation. A speculative design project that successfully unsettles an assumption, generates a public conversation, or makes a stakeholder uncomfortable in a productive way has achieved its purpose. This is a fundamental departure from the optimization mindset of commercial design.
3. Futures as Material
The Futures Cone, a framework developed by futures researcher Joseph Voros, building on earlier work by Charles Taylor and Norman Henchey, maps the space of possible futures into five nested categories – possible, plausible, probable, preferable, and projected.
Speculative design operates across this entire cone, sometimes working in the “probable” near future, sometimes in the “possible” far future, and sometimes deliberately exploring “preposterous” futures to reveal what is taken for granted today.
4. Radical Collaboration Across Disciplines
Speculative design is not something designers can do alone. Exploring future technologies, social changes, and ethical challenges requires knowledge from many different fields. That is why speculative design often brings together designers, scientists, researchers, writers, and even the communities that may be affected by those future ideas. Working across disciplines helps create more thoughtful and realistic future scenarios.
5. Embracing Ambiguity and Non-Resolution
Speculative design does not aim to give clear answers or perfect solutions. Instead, it encourages people to interpret and debate different possibilities. A speculative concept can feel both exciting and concerning at the same time, which helps spark deeper conversations about the future.
6. Ethics as a Core Design Constraint
Since speculative design explores futures that involve technologies, communities, and power dynamics, ethical consideration is crucial. Designers need to think about who benefits, who may be excluded, and how these future ideas could influence people’s thinking. The goal is not just to imagine the future, but to do so responsibly and thoughtfully.
The Speculative Design Process: A Step-by-Step Framework
The speculative design process is neither linear nor fixed. It is iterative, collaborative, and context-dependent. Nonetheless, most speculative design projects move through a recognizable sequence of stages. These include:
Stage 1: Research and Horizon Scanning
Every speculative design project starts with deep research into current trends, emerging technologies, social changes, and cultural shifts. This process, called horizon scanning, helps designers identify early signals that could shape the future.
Frameworks like STEEPLED (Social, Technological, Economic, Environmental, Political, Legal, Ethical, and Demographic factors) are often used to organize this research. The idea is to build future ideas based on practical evidence rather than pure imagination.
Stage 2: Future Scenario Building
After the research phase, designers create detailed future scenarios that are possible versions of the world shaped by current trends and changes.
These scenarios are not predictions. Instead, they are thought experiments that explore questions like:
- What could happen if these trends continue?
- What kind of society might emerge from these changes?
The Futures Cone provides a useful framework for placing each scenario in relation to likelihood and desirability, and for ensuring that the scenario set covers a range of futures rather than clustering around a single prediction.
Stage 3: Concept and Artifact Development
From each scenario, the design team derives a set of concepts for designed artifacts. These can include products, apps, services, interfaces, environments, or systems.
The purpose of these artifacts is to make future scenarios feel real and relatable. A strong speculative artifact should feel believable enough that people can imagine it existing in that future world.
Stage 4: Prototyping and Experiential Simulation
Speculative prototypes are created to communicate ideas and spark reflection, not to function like real commercial products.
These prototypes can take many forms, including physical objects, films, interactive experiences, exhibitions, or immersive installations. Some projects even place people inside simulated future environments to create stronger emotional and personal engagement.
Stage 5: Iteration and Critique
Speculative work is refined through discussion and feedback. Designers evaluate whether the scenarios and artifacts are raising meaningful questions and representing future issues responsibly.
This stage often involves testing the work with diverse audiences and refining the framing to ensure that the ambiguity is productive rather than merely confusing.
Stage 6: Documentation and Publication
Speculative design becomes impactful only when it is shared publicly. Projects are documented through exhibitions, videos, articles, publications, websites, or presentations.
The way a speculative project is framed and contextualized in its public presentation determines what conversations it is able to generate. Institutions like the MIT Media Lab, Superflux, and Dunne & Raby’s own studio have all built significant cultural authority through rigorous and sustained documentation of their speculative work.
Stage 7: Public Engagement and Dialogue
The final goal of speculative design is to encourage public discussion about the future. These conversations can happen through workshops, exhibitions, debates, community discussions, or policy events.
Success is not measured by finding a single answer, but by encouraging people to think critically about the future and recognize that it can still be shaped and changed.
Methods Used in Speculative Design
Speculative design is not a single method but a family of related practices, each suited to different contexts, audiences, and questions. The most effective speculative design projects typically combine several of the following methods within a single body of work.
1. Scenario Building
Scenario building involves creating detailed narratives or contexts in which a future might unfold. These scenarios are often informed by existing geopolitical events, social patterns, and new ideas. By exploring multiple “what-if” situations, designers can understand the consequences of different choices and paths, whether in politics, currency pairs, or buying property.
These scenarios provide a valuable space for long-term investors and organizations to consider both potential rewards and significant losses before they occur.
2. Design Fiction and Diegetic Prototyping
Design fiction, as articulated by Bruce Sterling, Julian Bleecker, and the Near Future Laboratory in their influential 2013 manual The Manual of Design Fiction, uses the grammar of commercial design to make speculative ideas feel real.
The core concept is the diegetic prototype. That is, an object that exists inside a fictional world (the diegesis) and which makes that world real for its audience.
A fake advertisement for a genetic modification service, a terms-of-service agreement from a surveillance state, a product safety label for a mood-regulating pharmaceutical — all of these are design fiction artifacts. These artifacts feel believable because they use familiar formats people already trust in everyday life, such as advertisements, product labels, apps, or official documents.
By presenting speculative ideas in realistic ways, design fiction makes people imagine that these future scenarios could actually exist.
3. Experiential Simulations and Speculative Prototypes
Unlike design fiction, which mainly shows future ideas through stories or artifacts, experiential simulations allow people to actively experience those future scenarios.
Methods like Stuart Candy’s Experiential Futures use immersive environments, role-play, and interactive experiences to help people feel what living in a possible future might be like. This approach creates a deeper emotional connection, making future challenges and possibilities easier to understand and remember.
4. Discursive and Critical Design
Discursive design and critical design challenge dominant narratives by presenting alternatives. These methods encourage people to question the assumptions behind current trends, new technologies, and emerging financial products.
Through provocative artifacts or exhibitions, they explore themes such as inequality, surveillance, or automation, encouraging society to rethink the systems they take for granted.
5. Cultural Probes, Role-Play, and Co-Design Workshops
To ensure inclusive thinking, speculative design often involves public participation. Cultural probes (interactive tasks given to participants), role-play, and co-design workshops invite diverse stakeholders to contribute their visions.
This collaborative environment allows a wider set of new ideas and perspectives to surface, breaking echo chambers and revealing how many speculators might view or influence potential futures differently.
Notable Speculative Design Projects
The following projects are among the most significant in the field's history — each has shaped the practice, extended its reach into new domains, or demonstrated the power of speculative methods to generate genuinely consequential public conversations.
MIT Media Lab — Cocoon (Dream Engineering)
Developed by the Fluid Interfaces Group at MIT Media Lab, Cocoon is a speculative device designed to enable users to shape the content of their own dreams through the delivery of external stimuli timed to specific sleep stages tracked through biometric monitoring.
Cocoon offers a profound exploration of the dream world. It goes beyond the ordinary, allowing users to shape their dreams with external stimuli such as scent, audio, and muscle stimulation. This project underscores the Media Lab's commitment to investigating uncharted territories, blurring the lines between disciplines and experiences. It encourages us to reflect on the evolving landscape of dream engineering technology and its ethical implications.
Lucy McRae — Compression Carpet
Compression Carpet is a speculative machine designed by Lucy McRae that recreates the feeling of a human hug through controlled physical pressure.
The project explores how technology might respond to growing emotional isolation and the human need for physical connection in a digital world. Rather than being a real product, it is a provocative concept created to spark conversations about intimacy, technology, and human emotions.

How Speculative Design Creates a More Desirable Future
Speculative design’s contribution to creating better futures operates at two distinct levels: the organizational and the cultural.
At the organizational level, speculative design gives institutions and companies tools for thinking more imaginatively about the long-term consequences of their decisions. By developing evidence-based scenarios of possible futures and testing their strategies, products, and policies against those scenarios, organizations can identify risks and opportunities that shorter-horizon planning processes would miss. They can make more robust, flexible decisions that hold up under a wider range of possible futures.
At the cultural level, speculative design contributes to the expansion of what a society believes is imaginable and therefore worth fighting for. The dominant culture of technological development operates under a set of implicit assumptions about what the future looks like with more connectivity, automation, convenience, and efficiency. It challenges these assumptions by making visible the full range of possible futures and helps people imagine alternative futures with different values, priorities, and ways of living.
This is why speculative design matters, as it gives people a way to question and influence the futures being shaped by governments, corporations, and technology companies.
Rethink the Future Through Design
Speculative design is not only about predicting the future, but it is also about questioning it, challenging assumptions, and exploring better possibilities before they become reality. It helps organizations, designers, and innovators think beyond short-term solutions and create more thoughtful and human-centered futures.
At Onething Design, we help brands and product teams use strategic design thinking to build meaningful digital experiences and innovation-led products grounded in human behavior and long-term impact.
Let’s collaborate to design future-ready experiences that create meaningful impact.
