The linked paper “Hierarchical Complexity: A Formal Theory” is very interesting and quite short. If you ignore the references it is only 12 pages long. It starts from the very simple case of explaining how to formalize the idea that (1+2)*3 is more complicated than (1+2)+3. The paper develops its mathematical theory rather quickly. I was surprised the authors managed to create a psychological theory that was concrete enough to apply in practice. The authors describe the results when they used their theory to analyze two different studies.
Of course many methodologcal issues remain. However I was very impressed. If you are comfortable reading abstract math I recomend the paper.
