The journal has employed mixed research methods combining the literal reviews of past data and journals; and scientific experiments, which controlled the variables of income and social statues of respondents and asked people graduated from both independent schools and public schools a series of questions regarding major social issues related to social injustice, to investigate the different social and political attitudes from both groups. The results were that indeed independent schools tended to create attitudes that are more politically conservative and less sympathetic on social issues. This research also discovered that independent school attendees tend to perceive themselves as belonging to middle or upper middle class even in the case in which financial background and current situation is controlled. In addition, it is important to note that difference in attitudes between private and public educational program participants can be mitigated through completing university level of education.

The findings in British Social Attitude Journal are related to our main research in a way of predicting public opinions regarding independent schools to be negative, because the journal and its study clearly demonstrate the comparably lack of interest in addressing social inequality and sense of superiority of independent school attendees in contrast to the worldview and self-perceptions held by students from public school; and it is reasonable to believe that such different worldviews will generate a certain degree of negative impressions on public school among U.K general publics (who are much more likely having received public education than private education). The research methods in British Social Attitude were conscientiously constructed, as for each data obtained, the study controlled the income and social status factors to reduce noise. Generally speaking the findings generated by the journal are reliable except in few cases, such as the study on perception of just salary for each career, the sample size of representatives of independent schools seem to be too small (below 100 respondents). Future studies on similar topics should give more effort on gaining a larger sample size of private school attendees to obtain a more credible result with less possibility of being disturbed by outliers.
