What is an example of expert opinion?

expert opinion is an opinion that has been extensively researched and has little to no holes. i cant think of an example but it could also be considered an experts opinion like glen beck and his show is all based on expert opinion hope this helps

Expert opinion is a recommendation or evaluation that is provided by a person who is both unbiased and knowledgeable in the subject matter. Glen Beck does not qualify because he is not knowledgeable about many of the subjects he evaluates and he is biased toward a conservative viewpoint. A good example of an expert opinion would be a Doctor Who specializes in bone fractures giving an opinion after evaluating an x-ray as to whether a bone is broken.
