Users prefer to start working with a system immediately, no matter how complex the system might be. They usually want to start completing tasks without having to worry about reading documentation or following tutorials. This means that many users learn by trial and error. Designers should work to support this type of learning by allowing them to experiment safely. Offering previews of the result of an action in the system can offer this type of support.

UI example (from article) showing "preview" design to support "learning by doing"

"if you're doing something where people do have to learn because it's not the general best practice, I would really strongly reccommend doing a lot of usability testing under learnability, bc that could be an impediment for a lot of people, and they may just go away, and never reach the level of expertise"
