> It's often better to allow mistakes but also offer immediate explanatory feedback if something is incorrect. Which is what the rule actually describes. > If users make an error, the interface should offer simple, constructive, and specific instructions for recovery. For example, users should not have to retype an entire name-address form if they enter an invalid zip code but rather should be guided to repair only the faulty part. Erroneous actions should leave the interface state unchanged, or the interface should give instructions about restoring the state. I'm very confused by some of the attempts at "gotchas" in this discussion that are just restating what the list (and context paragraphs) already say as if it didn't say it.
