Enron was rated investment grade by Moody’s, Standard and Poor’s, and Fitch until four days before it declared bankruptcy - scarcely a ringing endorsement of the agencies’ acumen. Even before Enron, the rating agencies had come in for significant criticism. Yet many investors who lost considerable sums in the financial crisis are saying that they relied on the rating agencies. How can this reliance be reconciled with what preceded it? I argue that an adaptive trait - incorporating new data that potentially conflicts with one’s pre-existing worldview so as to preserve as much of that worldview as possible - proved to be maladaptive in this circumstance. There was a plausible story investors could tell themselves about why the rating agencies could ‘get it right’ about the complex securities at issue while having gotten it spectacularly wrong about Enron. It will be interesting to see how, and how much, the agencies’ recent failures affect investors’ beliefs and practices.
