Yes, its all in approach. Two examples in regards to the 10% brain thing:
Someone: "You know, you only use 10% of your brain!"
You: "Actually, that has been debunked forever now. If you had just searched on Google you'd have known this. It's totally false, you use your entire brain yada yada yada."
vs.
You: "Yeah, someone I know told me that before and I thought it sounded really weird, so I googled around and found out that it turns out it's not actually entirely true! Pretty crazy, eh? It turns out, you use your entire brain yada yada"
The former is "you are dumb, if you used the internet or was as smart as me you'd know better" The latter is "hey friend, let me tell you a story about how I found out about how that's not true. You could have found this out too, but I'll save you the time and tell you what I uncovered."
More succinctly "You're dumb, I'm smart" vs "Check this out, friend."
