The Only Intuitive Interface Is The Nipple

The phrase "the only intuitive interface is the nipple" has become a popular adage in discussions about computer user interfaces. However, its origins and evolution are somewhat murky. Some attribute the quote to Bruce Ediger, though he has denied it was his own. The earliest known mention appears to be in August 1994, when Scott Francis used the nipple as an example of an intuitive interface in response to a question about user interface metaphors.

A more similar phrasing emerges in January 1995 from Jay Vollmer, who wrote that "the only truly intuitive interface is the nipple." Bruce Ediger seems to have encountered Vollmer's post and adopted a similar sentiment in his own writing shortly thereafter. By February 1995, Ediger published a variant of the quote, stating that "the only really, truly intuitive interface is the human nipple."

Later that month, another writer added the phrase "it's all learned" to the end of the statement. By this time, the idea of the nipple as the quintessential intuitive interface had become a common trope. Ediger even refined his own version to "There is no intuitive interface, not even the nipple. It's all learned," capturing the notion that all interfaces require learning, with the nipple being the ideal example of something that merely requires no learning at all.

So while the exact source of the quote may be uncertain, the idea of the nipple as the epitome of intuitive interface design has persisted for nearly three decades.
