 +===== Context ===== 
 +/* fill in contexts here: */ 
 +  * [[contexts:​User Interface Design]] 
 +===== Principle Statement ===== 
 + 
 +Any list should not contain more than 7±2 items. 
 + 
 + 
 +===== Description ===== 
 + 
 +Lists such as items in the main menu of a program or bullets on a presentation slide should be limited to 7±2 items. 
 + 
 + 
 +===== Rationale ===== 
 + 
 +The human short-term memory is limited. Research shows that one can remember 7±2 chunks of information. 
 + 
 + 
 +===== Strategies ===== 
 + 
 +  * Divide a long list into sub-lists adhering to the rule. 
 + 
 + 
 +===== Caveats ===== 
 + 
 +Note that this principle is questioned. 
 + 
 +See also section [[#​contrary ​principles]]. 
 + 
 + 
 +===== Origin ===== 
 + 
 +  * The original source for 7±2 is thisGeorge A. Miller: //​[[http://​www.psych.utoronto.ca/​users/​peterson/​psy430s2001/​Miller%20GA%20Magical%20Seven%20Psych%20Review%201955.pdf|The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information]]//​ 
 +  * How this became a design rule is unknown. 
 + 
 + 
 +===== Evidence ===== 
 +/* Comment out what is not applicable and explain the rest: */ 
 +/*  * [[wiki:​Proposed]]*/​ 
 + 
 +  * [[wiki:​Examined]]:​ There is scientific research concerning the short-term memory((George A. Miller: //​[[http://​www.psych.utoronto.ca/​users/​peterson/​psy430s2001/​Miller%20GA%20Magical%20Seven%20Psych%20Review%201955.pdf|The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information]]//​)). But this does not apply to any aspect of design directly. 
 +  * [[wiki:​Accepted]]:​ The principle is widely stated as a (user interface) design rule. 
 +  * :!: [[wiki:​Questioned]] :!:: It is highly doubtful to directly making a limit for memorizing digits to a generally applicable design rule. There is no evidence suggesting a rule that a list should not be longer then 7±2 items(([[http://​www.edwardtufte.com/​bboard/​q-and-a-fetch-msg?​msg_id=0000U6&​topic_id=1|The magical number seven, plus or minus two: Not relevant for design]])).
