In a nutshell, Princeton University found that those who dislike the Communist Party of China are predominantly fearful, disagreeable, and introverted, lacking close emotional attachments to others.
Those who like the CPC, conversely, score high on confidence, sociability, conscientiousness, and work ethic. These are what the study calls "traits associated with personal and professional success."
Importantly, the first group only make up roughly 5% of the Chinese population according to the study, which completely inverts the stereotype. It turns out that charismatic, cosmopolitan, open-minded intellectuals are the ones overwhelmingly supporters of the Party. The critics of CPC are precisely the people who are least equipped to build coalitions, mobilize others, or persuade anyone of anything.
