Nothing About Us Without Us: The Principle That Shapes Inclusive Design

“Nothing about us without us” (Latin: nihil de nobis, sine nobis) is the foundational principle of the disability rights movement. It asserts that policies, programs, and products affecting people with disabilities must be developed with the active participation of people with disabilities, not merely for them. In the context of inclusive design, this principle demands that disabled people are involved as decision-makers, not just as test subjects or afterthoughts.

Origins

The phrase has deep historical roots in democratic governance movements across Central Europe, but it was adopted and popularized by the disability rights movement in the 1990s. James Charlton’s 1998 book, “Nothing About Us Without Us: Disability Oppression and Empowerment,” articulated the principle as a direct challenge to the medical model of disability, which positions disabled people as patients to be treated rather than citizens to be included.

The principle was formally adopted in the development of the United Nations Convention on the Rights of Persons with Disabilities (CRPD) in 2006, where disability organizations played a central role in drafting the treaty.

What It Means for Design

Applied to digital product design, “nothing about us without us” means:

Disabled people participate in research

User research should include people with disabilities from the earliest stages. Not as an accessibility add-on after general research is complete, but as core participants whose insights shape the product direction. See inclusive design research methods and user testing with people with disabilities.

Disabled people co-create solutions

Co-design involves disabled people in generating ideas, creating prototypes, and making design decisions. Their role is creative partner, not validation checkpoint.

Disabled people evaluate outcomes

Accessibility testing must include people who use assistive technology in their daily lives. An expert audit measures conformance to standards. Testing with disabled users measures whether the product actually works for the people it is supposed to serve.

Disabled people hold positions of influence

Organizations serious about this principle hire disabled people as designers, developers, product managers, researchers, and accessibility specialists. See hiring accessibility specialists. Representation within the team ensures that disability perspectives are present in every decision, not just the ones explicitly labeled as “accessibility.”

What It Does Not Mean

It does not mean every disabled person speaks for all disabled people

Disability is diverse. A blind person does not represent the experience of a person with cerebral palsy. A wheelchair user does not speak for someone with autism. Include diverse disabled perspectives, not just one representative.

It does not mean non-disabled people cannot work on accessibility

The principle is about inclusion, not exclusion. Non-disabled designers, developers, and researchers can and should work on accessibility. The principle requires that they work alongside disabled people, not in their absence.

It does not mean consensus is required for every decision

Inclusive design is still design. Decisions must be made, trade-offs must be evaluated, and priorities must be set. The principle requires that disabled people are at the table when these decisions are made, not that every decision requires unanimous agreement.

Applying the Principle in Practice

1. Include disabled users in your persona development to ensure personas are grounded in real experience.
2. Run co-design workshops with disabled participants for major features or redesigns.
3. Conduct usability testing with disabled users as a standard practice, not an exception.
4. Hire disabled people in design, development, and leadership roles.
5. Compensate disabled contributors fairly for their time and expertise.
6. Report back to disabled participants on how their input influenced the final product. This closes the feedback loop and builds trust for future collaboration.

The Consequences of Ignoring It

Products designed without disabled input:

• Contain accessibility barriers that checklist compliance cannot detect.
• Solve imagined problems while missing real ones.
• Generate resentment in the disability community, making future research recruitment harder.
• Miss innovative solutions that only emerge from lived experience with disability.

The disability simulation approach, where non-disabled people try to imagine disability rather than engaging with disabled people, is a common manifestation of ignoring this principle.

Key Takeaways

• “Nothing about us without us” demands that disabled people participate in decisions that affect them, including product design decisions.
• Include disabled people in research, co-design, testing, and your organization’s workforce.
• Representation must be diverse; one disabled person cannot speak for all disabilities.
• Compensate disabled contributors fairly and report back on how their input shaped outcomes.
• Products designed without disabled involvement consistently miss barriers and solutions that only lived experience reveals.
