TRUST TOOLKIT
The Trust Toolkit is a practical, research-based framework that enables developers and innovators to assess how end users experience trust when interacting with a digital solution. Developed by Twinds – experts in digital trust, identity and experience design – in collaboration with Summon, social scientists and psychologists specialising in trust perception and strategic futures, it combines design and behavioural science expertise to translate academic trust research into applied practice.
Grounded in long-established scientific research on trust, it offers structured methods – including validated surveys and interpretive guidance – to measure how development and design choices, communication, and system behaviour influence users’ experience and perception of trust.
Developed within the DRG4FOOD project, the Toolkit evolved from a recognised research and development need: to provide a way to validate the assumed value of responsible digital design. Building more responsibly is widely understood to generate trustworthy solutions – yet until now, this has rarely been measured or evidenced. While frameworks such as the Digital Responsibility Goals (DRGs) guide teams toward developing more ethical and trustworthy technologies, the Trust Toolkit makes it possible to test whether those efforts actually result in technologies that are trusted by their users.
By introducing a measurable dimension to trust, the Toolkit strengthens the case for responsible design itself – giving developers, product owners, and solution architects credible data to demonstrate impact and to advance a more trustworthy digital ecosystem.
WHY THIS MATTERS
Trust is the foundation of every meaningful interaction between people and digital technology. Without it, even the most well-intentioned innovation can struggle to gain adoption or sustain long-term value.
As digital systems become more complex and embedded in daily life, earning and sustaining trust has become both more challenging and more essential. Frameworks such as the Digital Responsibility Goals (DRGs) provide guidance for designing ethically and responsibly, but the true impact of those efforts depends on whether users actuallyexperience the resulting technologies as trustworthy.
This is why the ability to measure trust matters. Trust is relational and contextual – it reflects how people feel when engaging with a system – while trustworthiness is demonstrable and designable. Understanding both is crucial to closing the gap between responsible design intentions and lived user experience.
By focusing on trust as a measurable outcome, organisations can make responsibility visible and actionable. Insights drawn from trust assessments can help product teams refine features, improve transparency, and strengthen accountability – building technologies that not only meet ethical standards but also earn genuine user confidence.
In this way, trust becomes the bridge between responsible design and real-world adoption, reinforcing the value of developing digital solutions that are truly deserving of it.
WHAT THE TOOLKIT DOES
The Trust Toolkit is being developed to help teams understand how their design and development choices influence user trust over time. It combines quantitative and qualitative methods to trace the dynamics of trust formation – from expectations to experience – giving developers practical insight into how trustworthy their solutions appear and how that perception evolves through use.
The evaluation begins before interaction, using guided reflection and survey instruments to capture users’ images of trust: their expectations, assumptions, and desired experience of a new digital service. This establishes a baseline of trust orientation – how optimistic or cautious users feel, what they consider essential for trust (e.g., transparency, accountability, security), and where they anticipate risks.
Participants then engage with the digital solution in a real or simulated scenario. Standardised surveys and behavioural observations are desiged to record the actual trust experience across multiple dimensions such as reliability, transparency, competence, integrity, benevolence, security, and usability – constructs grounded in scientific trust research but also well aligned with the Digital Responsibility Goals (DRGs).
By comparing pre- and post-interaction results, the Toolkit identifies trust deltas – shifts between users’ expectations and their experience. These deltas are particulalry valuable in providing insights into the features or interactions that strengthen trust and which may erode it.
For example, a pilot might show that transparency scores rose after introducing a clear data-use dashboard, while perceived autonomy declined when consent options felt limited or difficult to understand. Such insights highlight where design changes can directly improve trustworthiness. Further, qualitative feedback can deepen understanding of why these changes occur, allowing developers to link measurable trust outcomes to specific design and communication choices.
Together, these insights form a feedback loop: evidence that responsible design principles not only align with ethical goals but also translate into solutions that users genuinely trust.
The Toolkit is being developed as an open-source resource, enabling adaptation across domains where trust plays a decisive role. It aims to offer a common language for evaluating trust, fostering collaboration between researchers and developers, and building a cumulative understanding of what makes digital technologies both trusted and trustworthy in practice
HOW YOU CAN USE IT
For developers and product teams: The Toolkit will provide two ready-to-use surveys (Survey A and Survey B) that can be deployed independently or together to assess how users experience trust before and after interacting with a digital service. Both surveys will be published on GitHub as open-source, self-hostable tools, allowing teams to collect responses securely, export results to CSV, and analyse the “trust delta” between expectation and experience.
Each survey will be released as a lightweight, self-hostable web tool built on open web standards. The design prioritises privacy, accessibility, and methodological rigour: organisers can deploy the surveys directly from a public GitHub repository – for example, through GitHub Pages – or host them on their own infrastructure, connecting to an affordable, EU-based data backend such as Supabase for collecting and exporting responses. All data remain under the organiser’s control, with anonymous-by-default respondent IDs and simple CSV export for analysis – ensuring usability without dependency on commercial platforms.
While the survey interface and deployment can be freely adapted – for example, to support additional languages, branding, or local data-handling practices – the core question sets are standardised and grounded in validated trust research. This balance ensures both openness and scientific consistency, enabling results to be comparable across projects while still supporting localisation and reuse.
Documentation will guide setup, deployment, and basic interpretation – making it possible to integrate trust assessment into design sprints, usability testing, or continuous improvement cycles.
For researchers and innovators: The Toolkit offers a transparent, replicable approach for studying trust dynamics across contexts. Its survey instruments and data schema are grounded in established trust constructs, and aligned conceptually with the Digital Responsibility Goals (DRGs).
Researchers can contribute extensions or link them to behavioural and qualitative datasets to explore trust formation at greater depth. Over time, shared use and open-data contributions can help build a cumulative evidence base on what makes digital systems both trusted and trustworthy.

For organisations and evaluators: Beyond the self-service surveys, the Trust Toolkit will be complemented by expert-supported interpretation services for organisations seeking deeper insights. These services help translate trust-measurement results into actionable design and governance recommendations, linking quantitative data with qualitative context.
They are especially valuable for ongoing or large-scale evaluations – where trust needs to be monitored over time, embedded in feedback loops, or reported as part of accountability and impact frameworks.
By combining open access tools with expert guidance, the Trust Toolkit aims to make trust evaluation an accessible and credible practice for anyone developing digital solutions. It strengthens the feedback loop between responsible design principles and user experience – helping teams demonstrate, with evidence, that their technologies not only aim to be responsible but are genuinely trusted and trustworthy in practice.
CONTRIBUTION TO THE TOOLBOX
The Trust Toolkit strengthens the DRG4FOOD Toolbox by adding a method and tools for evaluating the impact of responsible design – complementing tools such as the DRG Playbook, which focus on how to develop responsibly, the Trust Toolkit closes the loop with the end user: offering a structured, research-based approach to measure whether digital solutions are recognised and experienced as trustworthy in use.
Its open-source components are currently in development, with pilot results and methodological insights being documented in a forthcoming paper on trust evaluation in responsible digital innovation – and will be made available via GitHub repository and DOI-registered publication.
IMPACT AND OUTLOOK
The Trust Toolkit represents a significant step toward making trust an actionable measure of responsible digital innovation. Through its pilot studies, the Toolkit has already demonstrated how systematic trust evaluation can reveal the concrete impact of design decisions – showing where technologies succeed in fostering confidence and where improvements are needed.
As development continues, the open-source release of the survey tools and accompanying documentation will enable wider use and collaboration across domains. These resources will support both researchers and practitioners in embedding trust assessment within design and development processes, helping to build an evidence base for what truly makes digital technologies trusted and trustworthy.
Looking ahead, the Trust Toolkit will evolve through feedback from its application in real-world contexts. The forthcoming paper on trust evaluation in responsible digital innovation will further consolidate its theoretical and methodological foundation, while continued collaboration within the DRG4FOOD ecosystem will guide its refinement.
Ultimately, the Trust Toolkit aims to make measurable trust a standard part of responsible digital design – closing the loop between ethical intent, technical implementation, and user experience, and advancing a culture of transparency and accountability across the digital landscape.
