Microsoft's inclusive design work reads every ability as a spectrum with three points on it:
permanent, temporary, situational. One arm is a permanent condition for some people, a broken wrist
for a few weeks, and a sleeping child for the next twenty minutes. Vision is a permanent condition,
an eye dilated at the optician, and low sun on a phone at a bus stop. Hearing is a permanent
condition, an ear infection, and a train carriage with no headphones in your pocket.

The three points are not a hierarchy of seriousness, and reading them that way is how the idea gets
misused. A situational barrier is milder, briefer, and easier to escape than a permanent one, and
pretending otherwise trivialises disability. What the spectrum is actually for is the fix. All three
points along one axis are cleared by the same design work, which means the number of people served
by a
[target-spacing](/target-spacing) decision, a
[contrast ratio](/contrast-ratio), or a caption track is far larger than the population that
particular criterion was written for. This is the [curb cut effect](/curb-cut-effect) stated at the
level of a persona rather than a pavement.

Use it as an argument, not as a substitute. It is the most effective thing to say in a room where
accessibility is being scoped as an edge case, because it moves the count from a minority to the
whole audience, and because everyone present has been situationally disabled this week.

It stops being useful the moment it becomes the only reason given. "We should fix this because
it also helps commuters" quietly concedes that helping disabled people was not reason enough, and
it invites a product decision to trade one group against the other. The honest framing is that the
requirement stands on its own, and the spectrum tells you how much wider than the requirement the
benefit runs.
