[Heuristic] Recognition rather than recall [Justification (From Nielsen)] Minimize the user's memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate. [Yes but...] 
Indeed the memory load should be lightened for a user. However the better way to do this is to employ well established visual and interaction patterns. Worse, this explanation can be very misleading for the naive reader. Indeed I have experienced many a designer and developer use this heuristic explanation to 1. attack progressive disclosure and 2. To create a ridiculously busy screen throwing all functionality with equal visibility into a "one-stop shopping" kind of screen. Or worse a screen with a huge amount of text explaining how to use the screen. All of which are from a cognitive ergonomic perspective completely unusable.
