The practice of stating opinions as if they are absolute facts without allowing for questioning or evidence; rigid, unthinking adherence to beliefs.
From dogma (Greek 'opinion, decree') + -ism (suffix forming doctrines/practices). The term emerged in philosophical discourse around the 1600s to criticize those who claimed certainty without proof.
Dogmatism is actually considered the opposite of skepticism in philosophy—and ironically, many early scientists had to fight against scientific dogmatism to make discoveries!
