It's been my experience some users do actually read in certain contexts
1) If they anticipate the action they're trying to perform will be complicated (such as an SSO login or hooking up Google Drive to desktop) 2) If their jobs require them to be well-read, such as professors or lawyers 3) If the stakes to them are high
Most tech companies nowadays that aren't enterprise don't typically deal with this until they're larger scale (and looking to land bulk accounts).
From our experience this is 100% true. It's so hard to miss this point when you are hard at work though.
That's why it's 100% vital to have a mockup and discuss everything at the design level before actually doing anything.
Still so relevant almost 20 years later.
