It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as Miller's law. [5 ...

[4] It was put forward in a 1956 edition of Psychological Review in a paper titled "The Magical Number Seven, Plus or Minus Two". [5] [6] [7]
Tufte emphasises that the experiment was about remembering nonsense data, and goes on to say that you can only reach the conclusion of "only 7 items belong on a list" if you don't read Miller's paper. This suggests that the current wiki-article's statement of "remarkable coincidences between the channel capacity of a number of human cognitive ...
George A. Miller suggested that the capacity of the short-term memory storage is about seven items plus or minus two, also known as the magic number 7, [2] but this number has been shown to be subject to numerous variability, including the size, similarity, and other properties of the chunks. [3]
Doritos are a revered snack for many. Now, scientists have found one of the ingredients in the triangle-shaped tasty tortilla chips has a superpower – it can make the skin of mice transparent.

Experimentally, it has been found that auditory presentation results in a larger amount of grouping in the responses of individuals than visual presentation does. Previous literature, such as George Miller's The Magical Number Seven, Plus or ...
