Miller observed that the memory span of young adults is approximately seven items. He noticed that memory span is approximately the same for stimuli with vastly different amounts of information—for instance, binary digits have 1 bit each; decimal digits have 3.32 bits each; words have about 10 bits each. Miller concluded that memory span is ...
From the days of William James, psychologists had distinguished short-term from long-term memory. While short-term memory seemed to be limited, its limits were not known. In 1956, Miller put a number on that limit in the paper "The magical number seven, plus or minus two".

(Hence, the title of his famous paper, "The Magical Number 7±2.") Modern perspectives estimate the capacity of short-term memory to be lower, typically on the order of 4–5 items, [27] or argue for a more flexible limit based on information instead of items. [28] Memory capacity can be increased through a process called chunking. [29]

According to wizarding legend, they can provide mastery over death if one person owns all three. The objects are generally remembered only as part of a fairy tale called The Tale of the ...
That limit—reflecting the capacity of short-term memory and originally estimated at seven plus or minus two items (Miller, 1956)—figures prominently in explaining performance in numerous cognitive tasks (Simon, 1990). Typically it is regarded as a constraint that hinders performance." (Kareev p.280) Reference: Kareev, Yaakov (2005) And Yet ...
