What makes you think I haven't?

As far as "official" academic publishing is concerned, I've been in touch with the editors of IEEE Software's "Voice of Evidence" column for about a year now, though on an earlier topic - the so-called "10x programmers" studies. The response was positive - i.e. "yes, we're interested in publishing this". So far, however, we haven't managed to hash out a publication schedule.

You've said so yourself, I'm making these observations publicly - though on a self-published basis as far as the book is concerned. I'm not sure what more would be accomplished by submitting a publication - but I'm certainly not opposed to that.

It's a lot more difficult, as has been noted previously on Less Wrong, to publish "negative" results in academic fora than to publish "positive" ones - one of the failures of science-in-general, not unique to software engineering.
