Make money from categorising nerds!

It seems to be universally recognised that confident people overstate their own abilities while the less confident undersell themselves.

Surely there's a space for an employment company to actually assess people objectively - particularly one in the IT space? In doing so, employers would be more sure of what they were getting and less confident people would get better jobs than they might otherwise - netting the employment agencies more money than they would otherwise.

Other ways to fund:

Large employer (Google?) offering standardised tests on the basis of getting first dibs on respondents.

Professional social networking site (is LinkedIn it?) charging for access to scores.
