Hugh Loebner establishes the Loebner Prize

Background

The Loebner Prize Competition is an effort to turn a philosophical question into a public test. The question is whether a machine can think, and it is tied to a challenge issued by Alan Turing in 1950 ^[1]. In the familiar Turing Test, a judge uses conversation to decide whether an unseen participant is a machine or a human. The test does not ask the judge to open the machine or inspect its code; it asks the judge to evaluate behavior. That behavior-based approach is what made the test adaptable to a competition.

The prize and its format

In 1990, New York philanthropist Dr. Hugh Loebner offered $100,000 for the first machine to pass the test ^[1]. Loebner was president of Crown Industries Inc. ^[1]. The offer attached a cash prize to a long-standing challenge and gave the contest a clear goal. The competition was a restricted version of the classic Turing Test: a computer had to emulate human behavior via a terminal well enough to fool human judges ^[1]. The terminal setting made the exchange concrete. Judges were not judging a machine's internal architecture or its designer's intentions; they were judging the text that came back through the terminal. The machine's task was therefore to produce human-like behavior in conversation, at least enough to mislead the judges.

The first contest

The first competition was administered by the Cambridge Center for Behavioral Studies and hosted by The Computer Museum ^[1]. It received funding from the National Science Foundation and the Alfred P. Sloan Foundation ^[1]. A panel of computer scientists, philosophers and psychologists oversaw planning ^[1]. These arrangements gave the contest institutional support from a behavioral-studies center, a museum, and two funders, and they brought several disciplines into the planning process. The mix was relevant because the Turing Test sits between computing, philosophy of mind, and the study of human behavior. The contest was thus organized as a judged event with outside funding and an interdisciplinary planning group, rather than as a single inventor's demonstration.

Early assessment and significance

The organizers were cautious about what the first contest could show. Daniel Dennett, chair of the Loebner Prize Committee, described the contest as still being at the paper airplane stage, while adding that one has to start somewhere ^[1]. That assessment places the prize at the beginning of a research program rather than at its end. The significance of the 1990 prize is that it made the Turing Test into a public competition with a defined cash award and a formal judging setup. It did not settle the question of whether machines can think. It created a venue in which machines could be tested by human judges under a restricted, terminal-based version of the test, and it gave that effort institutional backing. The paper-airplane image captures both sides: the effort was early and limited, but it was a deliberate first attempt.
