It is just as important to define concepts as it is to identify them. For example, diversity will actually mean different things in different circumstances. This is a subtle but important distinction- you must have a clear (if not absolute) definition of a cncept before you begin to research it.

What are the stakes? Money? Bragging rights? Public humiliation for the loser? The secrets of creation? (I have a sneaking suspicion that this will not be considered, considered a substantive annotation, so I will make an extra).

Very important. You can create a false impression easily simply by omitting information, as opposed to outright lying. The "sin of omission" is a huge and often unrecognized problem in researching information. If you know there is another side, please gather information about it. Ideally, study until you can understand why your opponents feel the way they do.
