xxiii Fads and crazes are those popular fancies that might be called “tremendous trivi- alities.” Ken Hakuta, no stranger to fads himself as the man who introduced the Wacky Wallwalker toy to America, defines a fad as “something everyone wants yesterday and no one wants tomorrow.” Fads and crazes lend themselves to italics, as in “The thing to do” or “Everybody’s doing it.” In what sounds like a malaprop- ism, fads are only “cool” when they’re “hot.” Though they often begin with youth, fads and crazes generally appeal to the masses, crossing demographic lines of age, income, and social class (even in our “classless” society). When Jacqueline Kennedy Onassis, the most famous woman of the 1960s, was seen doing the Twist or Frug in a miniskirt, social arbiters raised their eyebrows, then their hemlines. Often the adult population begins by looking askance at the current fads and crazes of youth, much like Cicero in ancient Rome who lamented “O tempora, O mores!” (“Oh the times, oh the customs!”). Adults adopt a bemused or cynical stance—until they themselves are caught up in the craze. At that point, young people have generally moved on. IN WITH THE IN CROWD In his book, Sixty Trends in Sixty Minutes, writer Sam Hill says, “Fads are short- term trends that are caused by popular momentum.” While that is certainly accu- rate, fads and crazes might also be long-term byproducts of our earliest development as human beings. Sebastian Junger, author of The Perfect Storm, wrote about human development in a June 2015 Vanity Fair article, “The Bonds of Battle,” stating, “Group affiliation and cooperation were clearly adaptive because in many ani- mals, including humans, they trigger a surge in levels of a neuropeptide called oxytocin. Not only does oxytocin create a glow of well-being in people, it promotes greater levels of trust and bonding, which unite them further still.” Introduction
