Trolleyology in the news

from today's Practical Ethics:

In the October edition of Prospect magazine, Practical ethics blogger David Edmonds provides an accessible and thoughtful insight into "Trolley problems"

A shocking memo leaked to Prospect, drafted by civil servants from the treasury and the department of health, exposes the stark reality of future cutbacks. Harsh decisions are inevitable, says the memo; in one NHS trust people on life-support systems are to be “finished off” on 1st November—either by smothering, or by having the plugs pulled out. Their organs are then to be used to save the lives of others on transplant-waiting lists, who have themselves become a considerable burden to the taxpayer. The total saving to the trust is estimated at £2.3m a year.
Hogwash, of course. But the government will make some tough choices in its spending review on 20th October, and these will cost lives. Whether “efficiencies” are made in the department of transport, the military or the NHS, there will be victims, even if they are unidentifiable. Governments always have to prioritise—choosing, for example, between a cheap medicine which benefits few people a little, and an expensive one which benefits many people a lot. But in hard financial times, such predicaments become more acute.
Moral philosophers have long debated under what circumstances it is acceptable to kill and why, for example, we object to killing a patient for their organs, but not to a distribution of resources that funds some drugs rather than others. To understand the debate you need to understand the trolley problem. It was conceived decades ago by two grande dames of philosophy: Philippa Foot of Oxford University (click here to read more about Foot) and Judith Jarvis Thomson of MIT.

David sums up both the nature of the burgeoning philosophical field of analysis of the trolley problem and its variants, but also the bigger questions about the role of such thought experiments in moral philosophy

The most vehement of trolley-phobes believe this whole approach to ethics is profoundly wrong-headed and, in a most fundamental way, mischaracterises the nature of morality. The world is too complex, judgements are too multifaceted, and the qualities of virtue and wisdom too subtle, for us to peel off intuitions from the trolley scenarios and usefully transplant them onto the real world. The riposte is that it’s hard to know how to do applied moral philosophy any other way. If it is indeed right to kill the spur man but wrong to kill the fat man, we need to untangle the principles at stake. Judith Jarvis Thomson once referred to the trolley problem as a “lovely, nasty difficulty.” Solving this lovely, nasty problem has repercussions for how we regard actions that weigh up lives.

Is the trolley problem a useful tool for moral philosophy?
If our intuitions lead us to not push the fat man, but to divert the trolley - does that mean that we should embrace the doctrine of double effect (or some variant of it), or does it mean that we should reject our instinctual responses to these questions?

Jim here: the trolley problem finds its way into countless public policy discussions--I'd be interested in collecting more examples if anyone runs across any.
