Sveet, it's naive to treat all 1st seed as being equal to one another, and the solution you suggest introduces practically the same amount of bias as you say my bracket arrangement does.
na·ive or na·ïve (n-v, nä-) also na·if or na·ïf (n-f, nä-)
adj.
1. Lacking worldly experience and understanding, especially:
a. Simple and guileless; artless: a child with a naive charm.
b. Unsuspecting or credulous: "Students, often bright but naive, betand losesubstantial sums of money on sporting events" (Tim Layden).
Thank you for opening with an insult. I am glad that you are approaching this discussion with such an open mind.
Sarcasm aside, I understand that you may feel this is personal, but I assure you I don't intend for it to be. I respect the work you have done and have no complaints. You are one of the finest TOs.
bi·as (bs)
n.
2.
a. A preference or an inclination, especially one that inhibits impartial judgment.
b. An unfair act or policy stemming from prejudice.
3. A statistical sampling or testing error caused by systematically favoring some outcomes over others.
By definition, changing the bracket after viewing the results of pools is a bias. And no, the different methods do not have "practically the same amount of bias". In the eyes of an unbiased TO, all first seeds should be considered equal.
I'm not saying completely disregard seeding at all. I'm saying that small changes in the seeding won't materially affect our test of skill hardly at all, and it has obvious benefits for the players. Once you get beyond a certain point, changing seeding by a 1-2 spots is practically irrelevant. To claim otherwise would be to claim that we have such precision in our ability to seed people that we really don't have. So I don't believe there is any reason not to switch say a 15th and 16th seed in a 32-man bracket if it avoids a regional conflict. It's unlikely that it will meaningfully affect the overall result of the bracket, it gives the players opportunities to play other people (which I think you can argue is a better measure of skill than playing people you play all the time), and it avoids the possibility of bracket manipulation.
If I can avoid a potential winners semis with Mango & Lucky on one side of the bracket and M2K and Cactuar on the other side by switching around two people of practically equal skill, why shouldn't I?
For one, it causes pool conflicts. First seeds and second seeds of the same pool are on opposite halves of the bracket and the same goes for third and fourth seeds. No two players from the same pool are in the same quarter of the bracket. Switching someone to the opposite side of the bracket will break this relationship and inevitably cause rematches from pools. The proper way to go about altering the bracket is to rewrite it completely, choosing different pairings of pools.
Each round, the person that advances has earned it. It is sad to eliminate your best friend from a national, but that is something the players need to understand may happen when they enter the same tournament as their friend. The role of a TO is to be as unbiased as possible, and indulging emotional arguments directly conflicts with that objective.
Until the Elo project is completed, it is hard to be completely unbiased when seeding pools, since a human must subjectively rank players by skill at some point. But remember, brackets are sort methods; they are cold and methodical. Like any sort method, the more iterations that are done, the more orderly the results, regardless of how chaotic the initial sample. My choice is to consciously minimize bias during initial seeding and impose no further bias, letting the player's performances determine the rest.
tl;dr It is impossible for the TO to make everybody happy, nor is it their place to attempt to. Someone will always rather have the bracket another way, but as soon as the TO makes a change to satisfy someone, they are committing a wrong on everyone else in attendance.
