Five-Star Theorem

The Five-Star Theorem is a scientific theorem that states that when any given person gives an item five stars on Amazon.com, they will, as a direct consequence of this, feel the need to buy the item again (even if it is not damaged, lost, or otherwise unusable). Extensive tests done on reviewers who gave Sonic the Hedgehog 2006 five stars have shown that this theorem must be true; the reviewers often ordered five or more copies of the game mere minutes after giving it five stars for no readily apparent reason. 
It has been suggested that this phenomenon was created by Amazon.com's scientists through subliminal messaging in order to make money. However, this suggestion was proven wrong, because all of the people who proposed it were suddenly too busy buying extra copies of Sonic 2006 to argue for it further.
