Post by Tommy GrandLike when you say everyone's obsessed with credentials,
I've experienced a good deal of this personally, for idiosyncratic
reasons. I actually have no serious professional qualifications in any
field that was identifiable 40 years ago -- which is why I am teaching
at MIT, a scientific university, where no one cared much about
credentials. I'm largely self-taught (including linguistics), and my
work happens to have ranged fairly widely. Some years ago I did some
work on mathematical theory of automata. At the time, I gave invited
lectures in mathematics and engineering departments at major
universities. No one believed that I was an accomplished professional
mathematician, but no one cared either; people were interested in
determining whether what I said was true or false, interesting or not,
susceptible to improvement and further work or not. On the other hand,
when I've worked in such areas as history of ideas or international
affairs, the reaction has commonly been quite different, ranging from
near-hysteria of an often comical variety to fury that I should even
dare to step upon this sacred turf without the proper letters after my
name. I don't think it's very hard to explain the difference, which is
quite striking.
