I'm not a new dev (but I am a new data scientist) and can definitely relate to what you said. I'm so used to "if you get stuck, just figure it out" as the norm for things I'm assigned to do, and getting used to "I'm stuck, I should reach out to someone who's more experienced than me" has been difficult. I'm always afraid of inconveniencing or interrupting my higher-ups, even though they never seem to be bothered by it. I guess it's just an irrational social fear.
