Source refs: `video:predictive-history-k-l9jbgo74@transcript:v1#seg-0054` - model: The class is framed as training imagination rather than transmitting facts: students build analytical models, test them by prediction, and then use them to reinterpret the past. Source refs: `video:predictive-history-lt8xlz78zvy@transcript:v1#seg-0003`, `video:predictive-history-lt8xlz78zvy@transcript:v1#seg-0005` - definition: The course is not meant to dictate conclusions but to augment imagination so students can build and test better models of reality. Source refs: `video:predictive-history-ajfxykt9joo@transcript:v1#seg-0003`, `video:predictive-history-ajfxykt9joo@transcript:v1#seg-0004` - model: Jiang says the three predictions capture the essence of Alexander's life, but he also instructs the class to be skeptical and ask whether the model's prejudice may make them unfair to Alexander. Source refs: `video:predictive-history-iturb48of9y@transcript:v1#seg-0006`, `video:predictive-history-iturb48of9y@transcript:v1#seg-0007` - model: He says a war-cause model can be refined by testing it against historical cases such as the Sicilian expedition and Operation Barbarossa.
