This study examined the relationship between person-environment fit, o
r environmental congruence (Holland, 1985), and satisfaction and super
visors' evaluations. The unique characteristics of the present study i
nclude (a) the fact that 24 tank crews of four members each constitute
d 24 environments, (b) the military conditions, (c) the method for ass
igning personal environmental congruence scores by comparing the perso
nality type of each crew member with the types of his crew mates, and
(d) examination of environmental homogeneity. Findings show positive c
orrelations around .40 (p < .05) between (a) person-environment congru
ence and (b) environmental homogeneity (the mean of the personal envir
onmental scores), and (a) satisfaction and (b) commanders' personal an
d crew evaluations. The findings enlighten the potential impact of env
ironmental congruence and of group homogeneity on satisfaction and per
formance.
