Passage Summary: We can now test people to see if they will get deadly genetic diseases, but since we can't cure them yet, telling people the bad news might actually do more harm than good.

Reasoning: New genetic tests can predict fatal diseases before they occur, but medicine cannot yet prevent these conditions, and the knowledge of an incurable fate can be psychologically damaging.

Analysis: This stimulus presents a moral and practical dilemma regarding the utility of information. The philosopher highlights a gap between our diagnostic capabilities and our therapeutic ones, suggesting that 'early warning' might be a burden rather than a benefit. When looking for a principle that illustrates this state of affairs, focus on the idea that providing information is only beneficial if it leads to a positive outcome or if the harm of knowing doesn't outweigh the benefits. It is a classic case of technology advancing faster than our ability to handle its consequences.
