According to these studies here: http://www.heterodoxacademy.org/2015/09/14/bbs-paper-on-lack-of-political-diversity/ And this one by Cambridge: http://journals.cambridge.org/action/displayAbstract;jsessionid=341D0D7E25BFE23DA0 Liberals over represent, empirically, all soft academic fields (psych, sociology, teaching, etc) and have created a hostile, discriminatory and homogenous community in the scientific fields through hiring and funding biases that are built off of biased studies such as the ones that "proved" that conservatives were dumber than liberals. [b][i]Hostility[/i][/b] In nationally representative polls, conservatives, liberals and moderates were asked whether they felt their political beliefs were under attack or biased against to which conservatives and moderates overwhelmingly responded yes while liberals responded no. [b][i]Discrimination[/i][/b] In another study analysed, 2 identical candidates were placed in front of liberal, moderate and conservative hiring agents with the only difference being between the 2 candidates being their political identity. The majority of the liberal agents openly admitting they would be biased against the conservative. Conservatives and moderates alike were overwhelmingly stating they wouldn't be biased. [b][i]Homogenous[/i][/b] Liberals are over represented in science fields by about 8x. Especially the soft sciences like psychology and such. This has led, as discussed and shown through empirical data, that liberals suffer from a stronger confirmation bias than conservatives [b][i]Confirmation bias[/i][/b] In a study conducted, two sets of equally accurate and correlative data was presented to 150 publishing firms for scientific research. One set showed a bias against whites and the other against minorities. The studies that "proved" (fake studies on both ends) white discrimination were published at significantly lower rates than the other set. [b][i]Lower intelligence conservatives[/i][/b] When analysed and attempted to be replicated, the studies that "proved" this claim was found to be heavily biased as operationally defining the right as social conservatives instead of including economic ones. On further studies and analysis, liberalism does not correlate to intelligence, social conservatives is a negative correlation and economic conservatism was found to correlate with higher IQs The video goes into more details and allows you to view the major parts of the study and meta analysis for free. :)
