I recently read somewhere that a Carnegie Foundation report said that 85% of a person’s job success is a product of interpersonal skills and that only 15% of his success is the result of technical knowledge. Which report was that, and how can I get a copy?

These statistics were extrapolated from A Study of Engineering Education, authored by Charles Riborg Mann and published in 1918 by the Carnegie Foundation. The cited figures come from the data on pages 106-107. The report is out of print, but can be located through a public library or a university library.
