Don't dumb yourself down. People will sense that you are not being yourself and you will be miserable anyway. I have made the same mistake myself in past and I have realised that often times people that you consider less 'intellectual' are capable of very stimulating conversation if given the right subject to talk about.
The key is to not be condescending. People don't mind smart people, but they hate being made to feel stupid. If you have to correct someone, do it in a kind, diplomatic matter.
People don't always have to be super smart to be interesting, even less intelligent folks have the ability to teach you something if you really show an interest.
I myself would rather spend most my time with 'boring', real live people than with a web browser in a darkened room.
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."
