"Hoarding" is a relatively new word. We don’t apply it to our hunter-gatherer ancestors who accumulated food, and we don’t apply it to the annual fall ritual of many families who dry, preserve and store food.
So when does accumulating food and other stuff change from good planning and preparation to a serious problem?
Validated as a DSM 5 certified disorder, compulsive collecting and hoarding is a recent development in the evolution of human behavior. Origins of the behavior are little understood and since most hoarders pose little danger to anyone other than themselves, they are largely seen as ‘odd ducks’ that make for good fodder for reality shows.
Nicole Pemberton of the SUNY New Paltz Evolutionary Psychology Lab in her blog, “How Much Is Too Much?”reasons that hoarding is a result of an evolutionary mismatch. And it has not contributed to any degree of happiness among contemporary hoarders. “The emotional duress, social isolation and clutter that it causes in an immediate environment can be harmful to our survival and to our well-being,” she says.
