I find that it's not specifically the kind of programming language, so much as the way the data is structured. Passing around big generic heterogeneous data structures makes it harder to just reason about state. That's a lot more common in dynamic languages, but I also see it happen plenty in, e.g., enterprise Java code.

In those situations, it's often just so much easier to set a breakpoint and take a peek than it is to waste brain cycles on thinking about what exactly you should even be printing in the first place.
