What is Miller’s Law?
Miller's Law George A. Miller (1920–2012) as part of his theory of communication. The law instructs us to postpone judgment about what someone is saying so that we can first understand their message without being affected by our own personal interpretations.
The law states that an average person can keep only 7 (± 2) items in his working memory or short-term memory. Prof. Miller observed that the memory span in young adults was limited to about 7 even though the stimuli contained varying amounts of information. This led them to conclude that bits, the basic unit of information, do not affect memory duration as much as the number of pieces of information to be remembered. The term "chunks" in cognitive psychology refers to a collection of basic familiar units that have been grouped together and stored in an individual's memory.
