This study investigated the extent to which a stereotype of Mexicans or Chicanos as fatalistic is supported by their locus of control scores. Original data for the paper came from locus of control scores on college students in four nations (U.S.A., Mexico, Ireland, and West Germany) and from Anglo and Chicano high school students in southern California. These data show the Mexican business administration students to be more internally oriented than is true for students from each of the other nations. Chicano high school students planning to enter college are also internally oriented, and match Anglo high school students planning to attend college. Only Chicano male high school students not planning to enter college showed any tendency toward a more external locus of control. The authors also look at locus of control data collected by Garza (1974) and by Reitz and Groff (1973) and find that these also fail to portray either Chicano university students or Mexican factory workers as fatalistic in outlook. The paper concludes that to the extent that a perceived external locus of control would be indicative of a fatalistic outlook, such perception is lacking in most data on Mexican or Chicano subjects.
