Self-Driving Car Ethics: Who Do They Decide To Kill? You?

CBS’s “Bull,” a drama about a jury consultant (played by “NCIS” alum Michael Weatherly) is an ethics mess…but then, so is the former jury consultant Weatherly’s  character is loosely  based on: “Dr.” Phil McGraw. The show does find some interesting ethics issues, however. A couple of weeks ago the story involved the programming in an experimental self-driving car. The issue: is it ethical for such a car to be programmed to kill its passenger if it has to make a life or death choice?

The ethical conflict involved is the so-called “trolley problem,” which is, as the name suggests, over a hundred years old. British philosopher Philippa Foot developed it into series of hypotheticals in 1967. In 1985, American philosopher Judith Jarvis Thomson scrutinized and expanded on Foot’s ideas in The Yale Law Journal. Here is one of Thompson’s scenarios:

“Suppose you are the driver of a trolley. The trolley rounds a bend, and there come into view ahead five track workmen, who have been repairing the track. The track goes through a bit of a valley at that point, and the sides are steep, so you must stop the trolley if you are to avoid running the five men down. You step on the brakes, but alas they don’t work. Now you suddenly see a spur of track leading off to the right. You can turn the trolley onto it, and thus save the five men on the straight track ahead. Unfortunately,…there is one track workman on that spur of track. He can no more get off the track in time than the five can, so you will kill him if you turn the trolley onto him.”

The problem: Now what, and why?

A. Throw the switch in order to maximize well-being (five people surviving is greater than one).
B. Throw the switch because you are a virtuous person, and saving five lives is the type of charitable and compassionate act a virtuous person performs.
C. Do not throw the switch because that would be a form of killing, and killing is inherently wrong.
D. Do not throw the switch because you are a Christian, and the Ten Commandments teach that killing is against the will of God.
E. Do not throw the switch because you feel aiding in a person’s death would be culturally inappropriate and illegal. Continue reading
