Does the Job Family section of the report simply repeat back to me what I said in the Questionnaire?

No. Next question?

...oh, sorry, you want more detail on that. Although the Questionnaire does indeed ask questions about job preferences, there is no direct connection between those answers and what appears in the report. The Job Families section of the report is based on matching the whole of your Birkman profile (several dozen independently measured "scales") against twenty-four reference samples of around 3,500 individuals each. The individuals in each sample are known to have a) success and b) tenure in those specific job families. So far from simply reflecting something you already said, this is definitely telling you something you didn't previously know: namely, who you most resemble in these 24 categories.

Powerful stuff.
