Seven pieces of information

The apparent deficiency of our short-term memory is a popular topic of conversation in our circle of friends.  We’ve all had moments of blankness when it comes to recalling what we did last night, or what we had for lunch today.  We blame it on aging and the general hectic pace of our world, but what if the answer simply lies in the physiology we are all born with?  What if our ability to store short-term memory has a surprisingly small limit?   A study by George A. Miller concluded just that.  It’s called, “The magical number seven, plus or minus two: Some limits on our capacity for processing information”(published in the Psychological Review in March 1956) and he concluded that the human brain has the capacity for storing only seven pieces of short-term memory.  Humans are fascinating creatures but unlike computers whose capacity exponentially expands with every passing year, ours stays fixed.

Seven pieces.  No wonder Twitter is so successful.  Such small bits to store and recall.
