  However, several authors have questioned whether such a simple equivalence captures the special complexities of what it is to G  intentionally.[3]  Here is an example adapted from Davidson [1980, essay 4]. Suppose that Betty kills Jughead, and she does so with the intention of killing him. And yet suppose also that her intention is realized only by a wholly unexpected accident. The bullet she fires misses Jughead by a mile, but it dislodges a tree branch above his head and releases a swarm of hornets that attack him and sting him until he dies. In this case, it is at least dubious that, in this manner, Betty has killed Jughead intentionally. (It is equally doubtful that Betty killed him unintentionally either.) Or suppose that Reggie wins the lottery, and having bizarre illusions about his ability to control which ticket will win, he enters the lottery and wins it with the intention of winning it [Mele 1997]. The first example suggests that there needs to be some condition added to (6′) that says the agent succeeded in Ging in a manner sufficiently in accordance with whatever plan she had for Ging as she acted. The second suggests that the agent's success in Ging must result from her competent exercise of the relevant skills, and it must not depend too much on sheer luck, whether the luck has been foreseen or not. Various other examples have prompted additional emendations and qualifications [see Harman 1976].
