The text "Mastering The Art of War" (Liu Ji & Zhuge Liang, Thomas Cleary translation) has some interesting advice for determining if someone is suitable for a leadership position:<p>>
"Hard though it be to know people, there are ways.<p>First is to question them concerning right and wrong, to observe their ideas.<p>Second is to exhaust all their arguments, to see how they change.<p>Third is to consult with them about strategy, to see how perceptive they are.<p>Fourth is to announce that there is trouble, to see how brave they are.<p>Fifth is to get them drunk, to observe their nature.<p>Sixth is to present them with the prospect of gain, to see how modest they are.<p>Seventh is to give them a task to do within a specific time, to see how trustworthy they are."
