Here is how they are not scientific:   In both cases, they are relying upon broadly based social science studies on the general population.    Then they make the leap to apply this to Google.    That's a very very big assumption.    Secondly, both have chosen to rely upon "science" while ignoring socialized pressures which may dominate what they claim "science" has proven.    (In actual fact, BOTH are social science and subject to very, very broad interpretation).    

As for scientific standards - neither Damore or Soh onformed to any scientific standards.    They both wrote essays relying upon research (not their own) that is not necessarily applicable to their arguments (actually very likely NOT applicable).      In other words, they had NO "scientific standards".
