Internal Validity

I read through it again and I think that it fits well in the limitation section. It makes sense and flows well with the organization of that page. I will perhaps add something to it, though.

Hi all, overall I think we have good reason to believe we have external validity for our scale. The questions look to be measuring what we want them to (face validity), seem to form a single factor (factorial validity), and don't correlate with most of the Big-5 traits (discriminant validity). While all of the points outlined in this section are true, after reading this section one is left with the view that our scale isn't valid, whereas, as I said, I think we have good reason to believe it is.
