Twenge et al carried out two meta-analyses of locus of control studies of young Americans, data included 97 samples of college students and 41 samples of children aged between 9 and 14 years
Twenge et al found that locus of control scores had become increasingly more external between 1960 and 2002
Twenge et al found that participants increasingly believed that their fate was determined more by luck and powerful others rather than their own actions
Twenge's research has positive and negative consequences
positive = more tolerant regardless of background -> believe situational factors shape everybody's lives
negative = feeling of hopelessness -> high levels of externality lead to this
Young people increasingly feel that outside forces control their lives
Research has found gender differences in locus of control
Semykina and Linz found that males are more likely to have internal locus of control and women are more external
usually attributed to differences in opportunities
Sherman et al said that everyone is becoming more external
Research has found cultural differences in locus of control
people in different cultures may also vary in terms of locus of control
collectivist cultures are more likely to blame external factors
suggests that locus of control may be passed on as part of a cultures tradition, explaining cultural differences in dependent and independent behaviour
