__NOINDEX__ Extravagance is unrestrained excess. Extravagant behaviour includes the frequent purchase of luxury goods. However, in psychology, "extravagance" can refer to various measures of human novelty seeking in which some of the behavior requires no particular monetary expenditure. Indeed, the phenomenon is not limited to individual human psychology -- extravagance can manifest itself in unrestrained excess of energy production seen in, for example, supernovae and cosmological expansion, and in modern industrial societies. One can even speak of the extravagant range of organism body forms, of species bioluminescence, and of scientific conclusions arrived at, in entomology. This article, however, addresses only the sense of the term that is indisputably encyclopedic: overspending.
