This is a somewhat famous person in America by way of her syndicated newspaper column, if folks don't know. If you read more about her and by her she is stunningly incurious. Her column amounts to silly trivia.
I can believe that she tests as one of the smarter people in the world in terms of mental horsepower. How has she harnessed that horsepower? She married some rich dude and apparently avoided ever doing hard work at any point in her life. She writes what amounts to a trivia column. Despite the potential she's got a big goose egg in terms of contributions to human understanding, tools, infrastructure, or knowledge. Never built or figured out a damn thing.
