意味
Expressing doubt.
文化的背景
Russians value 'искренность' (sincerity). Saying 'Я не уверен' is seen as more sincere than giving a fake 'yes' just to be polite. In business, 'Я не уверен' can be a tactic to gain more time for decision-making without losing face. Younger Russians might use English-influenced 'Я не шур' (I'm not sure) as a joke, but 'Я не уверен' remains the standard. In Russian academia, expressing doubt is a sign of a critical mind. It's common to start a critique with this phrase.
