I've heard this referred to as the "safety bell curve" - when you're new to a sport or dangerous activity, you don't know what you're doing and are at elevated risk. The same is true for people who have been doing that same activity for 10+ years: they stop actively thinking about their safety, and fall victim to human fallibility.
