All scientific models/theories tend to lie on a plane with the axes
"accuracy" and "ease of use". Explicability is also there, roughly
aligned with "ease of use".
Basically we should only keep those theories/models that lie on the
Pareto front, and discard those that are dominated. This is why we
still keep Newtonian gravity, even though it is less accurate than
GR (ie falsified), but discard the Ptolomaic system.
Cheers.
