While considerations based on simplicity and elegance have characterized the scientific thought since very early times, numerical naturalness, as most clearly formulated by 't Hooft and Wilson, has been especially influential in the search for theories of fundamental interactions. When applied to our current description of the microscopic world in terms of quantum field theory, it leads to the apparent paradox of the smallness of the electroweak scale and of the cosmological constant as compared to the Planck scale. In this Focus Meeting, Gian Francesco Giudice and Riccardo Rattazzi will review the concept of naturalness and its implications. The seemingly convincing notions of naturalness and simplicity in Effective Field Theory will be introduced and argued that they appear mutually contradictory in both the SM and its natural extensions. This state of things defines the Hierarchy Paradox. The hypotheses on which the naturalness principle rests, the consequences of relaxing some of these hypotheses, and the current attempts to develop new paradigms beyond naturalness will then be discussed.</span></p>
