This is a vain and self-servicing reblog. I really like the figures in this post (as a physicist).
Edit (2017): It seems that unfortunately the original, reblogged post is not available any more. It featured a diagram that visualized the results of GRE tests: Verbal and quantitative skills of graduates – as discussed also e.g. here (also showing the diagrams, for 2010) and here (diagrams lost, but links to original PDFs with data) and reviewed critically here. The diagrams looked very flattering for philosophy and physics majors 😉 Dan had written a thoughtful analysis which – if I recall correctly – also included arguments used in the critical review, like the self-selecting nature of degrees versus the alleged training you receive.
As physics undergraduates we used to joke (black humor) about why in hell we are studying physics when the corporate world (the world as such?) is ruled by people in the lower left quadrant of the skill matrix. OK, we used stronger language than ‘people in the lower left quadrant’.
Now and then I stumble upon anecdotal, yet powerful, evidence that this is true. Sorry Dan for using your thoughtful post for a rant of a reblog, I might add a more balanced update someday though all the business administration degree holders who will unfollow now are not going to read it.
