Oh. I haven't followed the link before commenting.

Now I did... and I don't really see the connection between the article and consensus. The most prominent example is how managers misunderstood the technical issues with Challenger: but that's about putting technically unsavvy managers into positions of power over engineers, not about consensus.

(I wonder if this is an example of a pattern: "Make a statement. Write an article mostly about something else, using arguments that a reader will probably agree with. At the end, a careless reader is convinced about the statement.")
