The trouble with assumptions: A reply to Jago and Ragan.

Comments on the work of A. G. Jago and J. W. Ragan (see record 1987-12114-001) that conducted a computer simulation to compare the 2nd author's (1964) contingency model of leadership with the Leader Match training program. It is argued that Jago and Ragan's computer simulation was guided by several theoretically and operationally incorrect assumptions that greatly reduce its meaningfulness.
