We put Charlie’s first public discussion about his multiple mental models approach in context of Berkshire Hathaway’s history and the $1 billion dollar bet Berkshire made on Coca-Cola in the late 1980s. We also make a unique discovery i.e. how the using multiple mental models to assess investment opportunities continues to be Berkshire Hathaway’s edge, as illustrated by the $60 billion dollar bet Berkshire on Apple.
