However, in analyzing the group stage results, it appears that our perceptions may actually be correct - Asia and Africa just don't do as well as CONCACAF nations in the World Cup, in terms of points and overall finish. Keep in mind that I have included Australia's 2006 World Cup appearance as part of Asia, even though they were not in the Asian Confederation at the time (AUS finished on 4 points in 2nd place in Group F).
Below is the average points per team and average group stage finish from World Cups 1994-2006. CONCACAF placed 12 teams in these World Cups (USA - 4 times, Mexico - 4, Costa Rica - 2, Jamaica - 1, Trinidad and Tobago -1). Asia placed 15 teams (Saudi Arabia - 4, Korea - 4, Japan - 3, Iran - 2, Australia - 1, China - 1). Africa placed 18 teams (Cameroon - 3, Nigeria - 3, Tunisia - 3, Morocco - 2, South Africa - 2, Senegal, Angola, Togo, Ivory Coast, Ghana - 1).
Average points/team:
CONCACAF - 3.083
Asia - 2.733
CAF - 2.722
Average group stage finish:
CONCACAF - 2.667
CAF - 3.056
Asia - 3.067
The averages aren't statistically significant, but they do show quite a bit of disparity between the CONCACAF nations and the other two confederations. However, as you can probably guess, Mexico's results really do a lot for the CONCACAF's averages. Out of CONCACAF's 37 aggregate group stage points, Mexico recorded 20 of them (just over 54% total). The other 8 teams that CONCACAF placed averaged 2.125 points/team and averaged a dismal 3.375 group stage finish (out of 4).
In recent World Cups, the other two confederations don't have a true dominant world-stage team like CONCACAF has had in Mexico. In the interest of fairness, I removed the top team in each of the confederations in each year (which is equivalent to CONCACAF minus Mexico, because Mexico was the top group stage team in each of the 4 Cups).
Average points/team:
CONCACAF (minus Mexico) - 2.125
Asia (minus top finisher) - 1.909
CAF (minus top finisher) - 1.857
Average group stage finish:
CONCACAF (minus Mexico) - 3.375
Asia (minus top finisher) - 3.454
CAF (minus top finisher) - 3.5
We can see here that the "CONCACAF's results are skewed because of the
Mexico Effect" argument has less merit when removing the top teams from the other confederations. The deviation between CONCACAF point average and Asia point average is 0.35 on the whole. In the second analysis, the deviation is 0.216. So, while Mexico's effect on CONCACAF's results is important, it doesn't wholly account for CONCACAF's successes.
I also took a look at head-to-head World Cup matches between these teams, although these are likely less significant because of the pots. A top team from CONCACAF, like Mexico, is more likely to be placed in a group with a lower-seeded team from Asia and Africa, and vice-versa. It should be noted that 2 Asian teams played in the same group in 2006 - Australia and Japan, because Australia was in Oceania at the time. Australia won 3-1. Regardless, in 15 matches between the confederations (W-D-L):
CONCACAF: 4-2-2
Asia: 4-4-5
CAF: 2-4-3
Despite playing 5 less games against the other confederations, CONCACAF nations have won as many games as Asian nations, and CONCACAF is the only confederation with a positive W/L.
Basically, if you define "more success at the World Cup" to mean group stage results, it appears that CONCACAF has indeed had much better results than Asian and African nations in the last 4 cups. Does that mean that CONCACAF should get more places and Asia/Africa less? Maybe. I think you might find a reverse trend if that were the case - more poor results from CONCACAF, and the elimination of goose-egg 4th place finishers like China in 2002 and Togo in 2006. If anything, I think this shows that there really are only a handful of world-class teams from these confederations at any given time - the rest are just filler teams. Some people could argue (successfully, most likely) that they should eliminate some of the extra Asian and African qualifiers and add another European or South American team, because replacing a team like 2006 Togo with a team like Guatemala likely won't produce much of a change.
