That 9-fold difference underscores that rational people can use different models with different assumptions and come to different conclusions. One important way that models can vary is in their level of abstraction, or level of detail that they cover. Are we better using a general impression, or using specific low-lwvel statistics and aggregating them? Here are some models you might choose:\n", "\n", "1. **Holistic**: I just feel that the Warriors have about a 1 in 5 chance of winning it all.\n", "2. **Game by Game**: I think the Warriors have an 75% chance of winning each game in the first round, then 65% for each game in the second round, but only 45% against the Rockets, then 55% if they make it to the finals. From that I'll calculate their overall chance.\n",
