For example, it’s very hard to be (a) indifferent between no new person, and a moderately happy person; (b) indifferent between no new person, and a very happy person; but (c) not indifferent between a new moderately happy person, and a new very happy person — so attempting to be all of these things at once leads to trouble from the perspective of various very plausible constraints on rationality (see Broome (2006)).
