Abstract
The increasingly popular concept of a hidden Hermiticity of operators is compared with the recently introduced notion of nonlinear pseudo-bosons. The formal equivalence between these two notions is deduced under very general assumptions. Examples of their applicability in quantum mechanics are discussed.
