You'd be surprised. Probably at both, but I hasten to get it in the conversation that static analysis is more than just static typing. By a long shot.

To me, simple static analysis can be over sold to the point that it is worthless. I swear, I see more effort put into detecting tabs versus spaces than I do things that actually reliably cause bugs. Seriously, unless you are writing make files, I just can't bring myself to care on tabs.

However, using some of the more advanced static analysis tools that don't just show where you forgot to do a null check, but also show where you pass in a null value... That is truly impressive and fixes bugs. Even better, these are things that can be used to harden a code base without having to rewrite it.
