     "[B. F.] Skinner misread both historical experience and then-existing research.  Punishment cannot be dismissed by science.  Carrots and sticks have their advangages and disadvantages, but both are effective in appropriate contexts. . . .
     ". . . forms of remediation [other than corporal punishment]. . . . are demonstrably less effective and more costly.  Something like isolating the child (detention) or even expulsion are costly for the child and, as history shows, relatively ineffective in changing serious bad behavior.  They deprive the kid of education, send the wrong message to his classmates, and . . . don't work very well.
     "Occasional corporal punishment for young males is cheap, damaging them less than exclusion from school, and it strengthens the role of teachers as legitimate authority figures.  It needs to be reconsidered."
