Except when the type system restricts you to homogeneous data-structures in inherently heterogeneous world. Herbert Spencer, the philosopher, could tell us a lot about it. As for crude and misleading clasdification - there is no shortage for them, especially in realms of psychology (hypohondric, sangvinic - all that nonsense) or economics and finance. The results of application of flawed economic/financial models based on flawed categories could be seen everywhere.
