This article is a fascinating portrayal of John Arnold, who made his initial fortune while at Enron (and was not implicated of any misdeeds while there, according to the article). A legend in the world of trading, after Enron he formed his own hedge fund and soon became one of the world’s youngest billionaires.

That said, the focus of the article is to highlight “bad science” resulting from rampant incentives that drive experimentation, and how the foundation he and his wife established seeks to address that through publicly tracking progress, failures and replication on a wide scale in order to validate or disprove results. It’s a refreshingly open, transparent approach, which may become an important benchmark in the future.
