Understanding the normal state of cuprate superconductors is surely crucial to an understanding of the superconducting state that emerges at lower, but still anomalously high, temperatures. I will summarize recent studies [1, 2] of the in-plane magnetoresistance in which a universal phenomenology of the magnetoresistance has been revealed across multiple families of cuprates. Distinct doping regimes are found to be characterised by distinct scaling behaviours [2]. It is argued that an explanation for the scaling and the universality of the behaviour is beyond any known form of Boltzmann transport. Finally, I will attempt to justify the need for two distinct components to the conductivity and explain the possible relevance of this dual character to the superconducting state [3].
