TL4 seems testable by asking what a ‘randomly chosen’ observer would expect to see. In fact, the simplest version seems falsified by the lack of observed discontinuities in physics (of the ‘clothes turn into a crocodile’ type).
Variants of TL4 that might hold seem untestable right now. But we could see them as ideas or directions for groping towards a theory, rather than complete hypotheses. Or it might happen that when we understand anthropics better, we’ll see an obvious test. (Or the original hypothesis might turn out to work, but I strongly doubt that.)
