In comparison to allocating resources to oneself, when allocating reso
urces to one's group, people are able to 'get away with' taking more t
han a fair and equal share because there exists an implicit justificat
ion that fellow group members will benefit. Such an implicit justifica
tion enables people to hide their self-serving motivation. Results rev
eal that subjects allocating a sum of money between their group and a
competing group took a significantly greater share of the resource tha
n subjects allocating between themselves and a competing individual. W
hether the allocation was made public or kept private had a significan
t impact on this relationship: the difference between group and self a
llocations was significantly greater when the allocation was made publ
ic than when kept private. However, subjects allocating only to themse
lves and in private were almost as self-serving as subjects allocating
to their group (both in private and in public). The only case where s
ubjects were overly constrained by equality was when they were allocat
ing to only themselves and the allocation was made public. (C) 1997 by
