The HAL 9000 explanation: “It can only be attributable to human error”

Originally posted on Humanistic Systems:

In 2001: A Spade Odyssey, there is a problem aboard Discovery One. The HAL 9000 computer, artificial intelligence which can talk and mimic the human brain, announces a problem.

HAL: “I’ve just picked up a fault in the AE35 unit. It’s going to go 100% failure in 72 hours.”

The AE-35 unit is a gyroscopic device used to maintain the communications link between with mission control by keeping the satellite dish antenna aligned with Earth.

Dr David Bowman goes outside the ship in a spherical Extravehicular Activity (EVA) pod to retrieve and replace the malfunctioning unit, and returned to the pod bay, where he and Dr Frank Poole carry out extensive diagnostics. They can’t find any defects. The pair radio Mission Control in Houston. Mission Control says that HAL, the supposedly “foolproof and incapable of error” 9000 computer may have made an error. Their SAL 9000 unit, the twin…

SHORTIES: Safety first — for whom?

In 1994, the American scholar Charles Perrow wrote an article named “Accidents in High-Risk Systems”, in which he reviews his theory of “normal accidents”.

On pages 14 and 15, he writes:

“Another interesting systemic factor that influences the number of accidents and their prevention is the matter of close proximity of elites to operating systems. (…) Thus, the nature of the victims im contact with the system should have some effect upon the safety of that system.”

This can be useful to understand why airplane hijackings are usually treated so differently from ship hijackings and why the aerospace industry is error-avoiding, while the maritime industry is error-prone, for example. The elite may be involved with shipping, but is committed to flying.
