SECTION 4 · lr

Young disputes West’s conclusion that Haynes is the worst inspector at the company. West cited the high proportion (50%) of returned defective appliances that were inspected by Haynes as support. In response, Young points out that Haynes inspects more than 50% of their sold appliances.

Young undermines West’s conclusion by disputing an implied assumption. West moves from a premise (Haynes inspected 50% of defective appliances) to a conclusion (Haynes is a bad inspector). West doesn’t say so outright, but his conclusion relies on the assumption that inspecting 50% of the defective appliances indicates that an inspector is bad.

Young provides more information (Haynes inspected more than 50% of all appliances) that casts doubt on this unspoken assumption.

Young doesn’t suggest that West presupposes that his conclusion is true. He contends that a presupposition underlying West’s conclusion is false.

Young questions the accuracy of West’s conclusion, not its relevance. Questioning its relevance would be saying that it doesn’t matter whether Haynes is the worst inspector. West, by contrast, gives a reason to believe that Haynes isn’t the worst inspector.

Young is disputing the accuracy of an unstated premise, not a stated premise. West has to assume that inspecting 50% of the defective appliances indicates that an inspector is bad, but he doesn’t explicitly state this. Compare to (E), which refers to a presupposition.

West’s conclusion is about a binary question: either Haynes is the worst inspector or he isn’t. There are no more or less extreme versions of it that Young could be arguing for.

A “presupposition” is an unstated assumption that must be true for a claim to make sense. West presupposes that inspecting 50% of the defective appliances means an inspector is bad. By providing context about Haynes’ share of inspections, Young challenges that presupposition.
