If anything is surprising about these poll-findings, it's that: the consistent and substantial inferiority of the "Business" major, as compared to all others; and the consistent (and, regarding job-pay, the substantial) superiority of "Sciences/Engineering."
This poll, of course, says nothing about an individual student's particular areas of interest or areas of personal strengths and weaknesses, which ought also to be factored into the individual's decisions as to which major should be pursued (if one isn't oriented instead toward a technical field that doesn't require any four-year degree at all). Obviously, any such career-path decision is, first and foremost, a decision about one's own interests and abilities. However, after those are determined, consideration of this Gallup-poll's findings should probably provide the remainder of a student's guidance, regarding what would be the most-rational career-path to pursue, all things considered.
