"Trauma-informed" is a phrase that has travelled a long way from its origins, and it is now often used to describe a training day rather than a design decision. We treat it as a set of properties a product either has or does not have.
Choice. Nothing starts without the person choosing it, and every experience can be left at any moment without penalty, explanation or a "are you sure?" that shames them for stopping.
Pacing. The person sets the speed. No countdowns, no streaks, no nudges engineered to pull someone back in. If a feature only works because it applies pressure, it does not belong in a product for people who have lived with pressure.
Predictability. Before anything happens, the person knows what it will be, how long it will take and what it will ask of them. Surprise is a design failure here, not a delight.
Reachability. Technology should never be the last thing in the chain. Support numbers stay visible, safeguarding routes stay open, and it is always clear that a person can be reached.
Safety in the small details, too: a quick exit that leaves no trace on screen, language that never implies fault, and no data collected that we do not genuinely need.
None of this is complicated. It is simply what happens when the people most affected are in the room while decisions are made.
