Simplicity

From Stacy McGaugh I have learned that MOND predicts the exponent in the baryonic Tully-Fisher relation to be exactly 4. It reminds me of how the hypothesis of a critical Higgs (in Shaposhnikov and Wetterich) directly predicted the actual mass. In both cases, the mainstream prefers models (dark matter, supersymmetry) which are less accurate, more complicated, and permit endless fiddling with details, over searching for models which implement the simpler and more accurate prediction. I believe this is the reverse of how things should be.

I also think that the "inflation criticality" of the Higgs, discovered by Bezrukov, equally deserves attention. But I am not aware of any mechanism which produces that property, whereas we do have models for MOND and the critical Higgs.
