EMPLOYMENT  PSYCHOLOGY

trained  examiners  working  under  his  supervision.  When
the  examination  includes  an  actual  demonstration  of  the
work  in  question,  a  technical  expert  who  has  been  familiarized ­
  with  the  psychological  technique  should  be  present.
The  ever  ready  cry  that  the  combination  of  employment ­
  methods  here  described  is  a  process  entirely  too
long  and  too  costly  can  be  met  only  by  calling  attention
once  more  to  the  fact  that  it  is  far  more  economical  and
effective  to  spend  time  in  selection  at  the  very  beginning,
by  means  of  a  method  developed  for  that  very  purpose,
than  it  is  to  allow  the  actual  selection  to  take  place  in  the
slow  grinding  wheels  of  an  organization  which  is  fitted
primarily  for  production  and  not  selection.  Natural  selection ­
  is  a  sure  and  an  inexorable  process,  but  it  is  far
more  drawn  out  and  much  more  expensive  than  artificial ­
  selection.
