Other forms: presumptions
A presumption is something believed until it is shown otherwise. The presumption of innocence, a rebuttable presumption, a fair presumption.
In law it decides who has to prove what: the presumption of innocence puts the burden on the prosecution, which is the foundation of criminal procedure. A rebuttable presumption can be overturned by evidence and an irrebuttable one cannot. The other sense is overconfidence — the presumption of it, what presumption — which is a quite different and rather old-fashioned complaint.
