Most information you find will be tainted. Secondary expertise almost always present information in a biased way. You will counter this bias both by being aware of the bias and by interviewing someone with a different view. Obviously it requires further study. This is the wonder of professional research - by collecting information from a variety of different resources, with a range of bias, we can create a superior assessment of the value of each item of information.
Research based solely on government research, no matter how well done, is poor in value.
The third unique skill is speed. We must be able to provide research as a service, as a business, and this involves far more than research. This involves banal work like copyright and legal protection, and challenging work like selecting effective external research expertise to supplement your experience. The skills of professional research are like the artist. They take a lifetime to learn.
