The first three sentences of the abstract contradict your comment; the scientists started with a question, not an assumption. >When dogs interact with humans, they often show appropriate reactions to human intentional action. But it is unclear from these everyday observations whether the dogs simply respond to the action outcomes or whether they are able to discriminate between different categories of actions. Are dogs able to distinguish intentional human actions from unintentional ones, even when the action outcomes are the same? It is newsworthy because new evidence has been found.
