I think that's precisely the point people have been talking past each other on here. I will have a go at reconciliation, albeit I'm not sure whether I'll succeed.
Consider two players,
X and
Y, consider also the universe of all possible Civ situations that these two players could face,
U (u1, u2, ...) Now, for different
u in
U,
X and
Y might disagree on what is the optimal play, in fact we should expect that they do so for plenty of
u. Let's define a mapping, for each player, of specific situations
u onto the space
[agg, peace], so that
x(u) = agg, for all
u where
X would see aggressive play as optimal and carry it out, and let's define
x(u) = peace, where
X would see peaceful play as optimal. Finally, let's define sets
AGGx,
PEACEx,
AGGy and
PEACEy to be subsets of
U, so that
AGGx includes all
u for which
x(u)=agg, and so on.
Now, Gavagai, just given that, we can state that
X has a propensity to attack greater or less than
Y, depending on the comparative sizes of
AGGx and
AGGy. It's simply a statement of set sizes and states nothing about what drives one player to have a larger sized set, specifically whether it's some sort of emotion, or his ability to plan aggressive actions better than peaceful ones. And the point is that
AGGgavagai really is larger than
AGGi, where
i is any number of players here at RB.
However, Gavagai's counter-point, and it's a worthy one, is that just knowing the size of
AGGx tells us very little about what
X is going to do in a specific situation. Sure, if you have
nothing else to go on, knowledge of
AGGx is useful. In practical terms though, who cares about this highly-aggregate proportion? Maybe
AGGx for a particular
X is high because he always declares war on people who have researched Military Science, and never on anybody else, sure, he will have a statistically high "propensity to attack", but the correct response to that is not to defend preemptively against his harrassment (assuming that it will come, because hey, he's "aggressive"), but not to research Military Science until you are confident you can beat him.
Now, a different point that seems to underlie the disagreement between Gavagai and others, is the implicit assumption that the size of
AGGx tells us something about a player's behavior across the board. That is, if a player's propensity to attack is high, this will likely manifest itself in many different situations. To clarify we can define some subsets of
U, by grouping together 'similar' situations, say settler races, and split these subsets in turn by whether a player sees an aggressive or a peaceful play optimal, as we did above when we created
AGGx. So we would get a bunch of subsets, say
SETTLEAGGx,
EARLYBORDERAGGx,
COASTALPROXIMITYAGGx, and their corresponding peace duplicates. Now, saying that some sort of general aggressiveness exists is the same as saying that the size of all these subsets are correlated, and most people here seem to subscribe to this assertion. And if it does, then yeah, we can take a person's manifest aggressiveness in one set of situations and usefully assume that he will manifest such aggressiveness in other situations. Gavagai's rejoinder is that no such correlation is necessary, that there can be specific subsets of
U, for which the size of the corresponding
---AGGx subsets would be high, but observing this tells you very little besides the point that this specific situation lend itself to war. The point is, the extent to which 'general aggressiveness' exists, that is the extent to which correlation in sizes of
---AGGx across many different identifiable subsets of
U exists, is an empirical question, it might exist for some players, but not for others. And I'd say it exists for Gavagai more than he would admit
For a practical example of all that abstract nonsense above, see the confession thread nearby, and the story of how observing a player in specific situations can lead to widespread and strong conclusions about the player, which are far more extreme than they should be.
