This is weird to read. What caught my eye:<p>"For an early stage, raw startup, your hiring focus should be on homogeneity."<p>then right away:<p>"You should be encouraging a diversity of origins (gender, ethnicity, etc.)"<p>I don't really care about one side of the argument or another, (homogeneity, heterogeneity) or even prejudices - but this seems inconsistent.<p>If you are advocating cultural homogeneity, except for political correctness or legal reasons (ie to avoid being sued by applicant you rejected because of their gender or ethnicity), why do you argue for diverse origins ?<p>Be consistent with yourself - it's A or B.<p>If it's A and B you may not really have an argument.<p>And I would really, really like to see facts supporting either homogeneity or heterogeneity. So far all I've seen are best described as case reports - no real trials with enough samples to have a good statistical power. Make teams of 100 persons, standardize on competence (SAT, whatever) then try and compare different mix of gender or ethnicities and pick up the top performing mixes. Do that multiple times. Then give a conclusion.<p>That's an argument I will be able to believe.<p>EDIT: some clarification - I don't care what anyone thinks/look like/believes as long as the person can deliver more than it costs, but I'm willing to consider that if conclusive evidence exists. The best I've read so far is a positive effect of homogeneity towards cooperation against others (parochialism).<p>EDIT2: to avoid statistical backslash, I realize that due to higher standard deviation in small samples of a given population, underrepresented genders or ethnicities may show a higher variance - hence the need to standardize beforehand on competence to select test subjects over a threshold and reduce this bias.
