In physics, for instance, a system’s observability determines how accurately its internal state can be inferred from external measurements, a concept formalized in control theory as the system's observability matrix. In social sciences, discussing a phenomenon’s havainnottavuuteen involves examining whether its effects are visible to observers or whether they remain hidden behind complex mechanisms.
