Common Sense I think is something people confuse with experience.
I used to run into it a lot where I would hit a brick wall with something, then get told, you should know better, common sense says to do this, and I'd go but I've never done this before, why the heck would I know that. Now that I'm more experienced, humanities tech base has increased to make research easier through the internet, and services are easier to outsource, I rarely run into situations now where I get called on for not having any common sense. It pretty much happens when I realize I'm in over my head and seek out help that it comes up.
