It's ironic in a way that calling for more diversity is now the safest, most orthodox position. The entire point of diversity in organisations is (or at least was, before it became a goal in its own right) is to avoid getting stuck in the same thought processes and so sacrifice commercial or other advantage. Of course that is demonstrably not how the real world works, and never was, it was pure management consultant fantasy. The MoD has one very practical and very pressing need to either do diversity wholesale, or return to its traditional ways: a desperate shortage of, errm, personpower...MOD the other day were talking about removing the laddish attitude from the services to make them more attractive to diversity.
I think it is more that if you have a hammer, every problem looks like a nail.Computers make people dumb, the gen X and boomers had to think more for themselves.
