It looks now that anarchy will be completely or mostly elimanated from the game due to the new preveiw info that just came out. You can see it here:

It does say that there won't be any fixed govs any more, like democracy or facism. Insteads there's sliders that reflect your societies veiws on things. For any of you that have played Hearts or Iron 2, I think they copied the best aspects of that games government system and are bringing it to Civ 4, which i'm very excited about! However I don't think this doesn't mean anarchy or transitional effects of government will be eliminated completey. Let's say you want your civ more democratic. You move the slider down more to free elections. This could cause some production, commerce or reasearch penalty's as your civ adjusts to the reforms, just like if u switch your economy to free market from central planning. This could give you a trade/ commerce penalty for a while, than give you bonuses after you've adjust.
