Shorts: Amar Bhidé on the deference of human judgment in favor of computer models.

Today, I heard HBR.org Ideacast titled Bringing Judgment Back to Finance where Amar Bhidé, author of a recent HBR article The Judgment Deficit and of a book titled A Call for Judgment: Sensible Finance for a Dynamic Economy was interviewed about the ideas in his article and book.

It is a fascinating cast and I would let you listen to it. I wanted to point to what in my view was the main idea. Over-reliance on computer models, both in finance and in other areas of life, is dangerous. While computer models and arithmetic based rules are important, they should not replace human judgment.

I must admit that when I prepared my No More Rules! presentation and wrote the MIX hack under the same title, I haven’t even considered cases where the rules are no man-made, but computer made. This, of course, leads to a different set of complexities (Hey, this is what the computer says). I think however, that the message is the same. We need people who think, how develop skill, judgment and practical wisdom. Rules, guidelines and arithmetic models are tools that should help human make decision, not replace them.

Interesting stuff!
