Here's an anecdoate, not to dispute the empirical finding.

I recently discovered McCabe (cyclomatic) complexity and found it remarkably good! In a tiny experiment, I ran it on a 50k Python code base with a threshold of 8, and the output almost exactly matched all of the already existing `FIXME: refactor this` comments. According to McCabe the threshold to look out for is 10.

p.s: if you write Python, you already probably have the mccabe package installed through flake8. Use it like so:

    $ python -m mccabe --min 8 foo.py
