Old Habits Die Hard

Description
This occurs when some kind of functionality is added later on to solve a problem, but the users are not motivated to use it or because of various reasons it's a hassle to use or learn.

Examples
An example from Facebook is that users wanted to post to a certain group of friends. Facebook later added the option to group friends, but at that point it was a hassle, because of the large amount of friends some users have.

Pros & Cons
When the users sees a problem, but still don't want to use your fixes, it's a bad and unwanted pattern. Being aware of this patterns means different measures can be used to ensure new functions are easy to use. In the case of the example, Facebook could have emphasized that you can group just some people, and maybe ask about grouping on friend requests.

Relations
The mechanic Deliberately Leave Things Incomplete may be one source of this dynamic. When the application later adds the functionality that the users want, it not done in an optimal way.
