Homo consumericus
Homo consumericus (mock Latin for consumerist person) is a neologism used in social sciences, notably by Gilles Lipovetsky in Le Bonheur Paradoxal (2006) and Gad Saad in his 2007 book, The Evolutionary Bases of Consumption According to these and other scholars, the phenomenon of mass consumption can be compared to certain traits of human psychology described by evolutionary scientists pointing out similarities between Darwinian principles and consumer behavior. Lipovetsky has noted that modern times have brought about the rise of a "third" type of Homo consumericus, who is unpredictable and insatiable.
