I will discuss recent progress (joint with Y. Harpaz) on the fibration method for proving the existence of zero-cycles of a given degree and rational points on varieties defined over number fields. The results are unconditional for zero-cycles, while in the context of rational points they depend on a conjecture on locally split values of polynomials which a recent work of Matthiesen establishes in the case of linear polynomials over the rationals.
