Meaning
Asking for confirmation of certainty.
Cultural Background
Poles often use 'Jesteś pewien?' as a form of 'social glue' to show they are paying attention to the details of what you are saying. It is not necessarily a sign of distrust. In Polish business, being 'pewien' is highly valued. If you answer 'Nie jestem pewien,' it is seen as honest, whereas in some other cultures, you might be expected to feign certainty. Younger Poles might find 'Jesteś pewien?' a bit dry and prefer 'Serio?' or 'No co ty?'. In some rural areas, you might hear the long form 'Jesteś pewny?' more frequently than the short form 'pewien'. Both are understood everywhere.
The Gender Rule
If you are unsure of the gender, use 'Na pewno?'. It's a safe, gender-neutral 'cheat code'.
Don't over-question
Asking 'Jesteś pewien?' too many times can make you sound like you don't trust the person. Use it sparingly!
