To put it crudely, theorists can be tempted to think along the lines If people as clever as us haven't explained it, that's because it can't be explained – it's just an accident. I believe there are at least two important regularities among standard model parameters that do have deeper explanations, namely the unification of couplings and the smallness of the QCD θ parameter. There may well be others.
