Even the “I believe in you” could seem kinda like the second one lol
You’re probably right that it can depend on the context (I even stated it myself), I’ve just never seen a “kind” “Figure it out for yourself” in the wild. IDK, I’m the type to explain it even if it’s stupid obvious, unless it’s something like “why is everyone mean to me after i insulted them and the thing they liked?” where it’s very obviously a troll, then I’ll be snarky and go “you tell me”
