Yes, it's a neat concept. Have you ever met someone who has unerringly bad judgment? Maybe it's useful to know a few and ask them for advice.
Not only did I buy a Zune, I was an early enthusiastic customer of their streaming subscription service and thought that it would topple the iTunes sales model. We all know how well that went.
I see the value here being: when you can’t understand the causal relationships for success, use the causal relationships for failure that you can understand and then avoid specific failure modes.
“Friend gives generally bad advice” is not that kind of a clear causal relationship.
