You're all almost never purely doing your own research, though. There isn't enough time for that. It's a sliding scale of deciding where to stop and how much to take for granted and who to take it from. This is why the problem isn't "doing your own research" vs "trusting someone". It's always both; the magic is in choosing which at each particular step when finding things out.
