Over time, Americans have had slightly differing views on personal responsibility for success or failure. In 1924 and 1977, approximately 47% of high school students agreed that it is entirely a person's own fault if they cannot succeed. The view that external factors like luck or upbringing influence success more than personal responsibility increased from 30% in 1924 to 40% in 1977. However, the majority of Americans have consistently believed that hard work leads to success and that people are primarily responsible for their own outcomes.
