Lost in math: how beauty leads physics astray

Most physicists think of beauty as the royal road to discovery; a leading critic shows it is instead the road to nowhereWhether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates trusted theories from disposable ones. This is why, Sabine Hossenfelder argues, physics hasn't made a major breakthrough in more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or string theory, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink how they do physics. Only by embracing messiness and complexity can science discover the truth, not as one might prefer it, but as it is.
