I contributed well-researched answers already when I was ostensibly a very junior dev, and even before that during my CS studies. Stuff you can lookup or simply try out is doable, of course questions where you need experience aren't a good fit.

When I was in high school I read the docs, and learned C++ from books and MSDN. Granted my access to the internet was rather limited back then, but it also never crossed my mind to bother people for things I could easily lookup myself.

Growing up in a RTFM, "search the forum first before asking" environment is seen as toxic today, but it really helps keeping certain behavior in check thats a drag on society as a whole.

One of the best mentors/bosses I ever had never answered coding questions directly, but always in the form of a question so I could look it up and learn for myself.

I try to do the same with my junior devs today, unless there's time constraints or they're under stress, I try to let them figure out the final answer themselves.
