If you are hiring for start up, you do not care why they are dumb. Potentially you can save money by hiring non traditional candidates and paying them less, but any advantage you get this way will be short lived. Unfortunately diamonds in a rough are rare and finding them cost more than their value.
I was originally replying to a comment that claimed that people became wealthy because of their intelligence. My point does not have much to do with the issue of startup hiring (admittedly making the thread a bit off-topic for the article).
