Majority, probably not. Most emergency checklists are going to assume the cockpit crew is the normal count and throwing an extra person is is going to cause more harm than good. The only exception I can think of is UA Flight 232 which while tragic probably would have been worse without someone else in the cockpit.
Yeah, I should have said, "the cases when the extra person is a benefit are probably more common than the cases where the extra person attempts to murder the crew and/or crash the plane".
