Cultural Background

Finns value 'asiallisuus' (matter-of-factness). Being 'vakuuttunut' is a serious commitment to a truth, not a casual remark. In Finnish universities, 'vakuuttuneisuus' is the goal of a thesis. You must provide enough 'vakuuttava' evidence to make the reader 'vakuuttunut'. The phrase is used in courts to describe the 'burden of proof'. The judge must be 'vakuuttunut' beyond reasonable doubt. Influencers use 'vakuuttunut' when reviewing products to sound more objective and less like they are just 'liking' something for money.
