In the middle of the 20th century, a group of researchers pronounced political ideology dead. They argued that most individuals do not know enough about their beliefs to have an ideology. While there is plenty of anecdotal evidence to this claim, the emergence of heated Tea Party protests and the overall Tea Party movement indicates that political ideology is alive and well. Social psychological research also backs up this claim (Jost, Nosek, & Gosling, 2008). Political psychologist John Jost and his colleagues have found numerous differences between those that have conservative and liberal ideologies, even though they may not be aware of it.
The strongest differences concern system justification and change (Jost & Hunyady, 2005; Jost et al., 2008). Specifically, conservatives are more likely to support maintaining the status quo or hold stronger system-justifying attitudes. For example, a New York Times/CBS News poll indicates that the Tea Party supporters are upset about the amount of support that the current United States administration is giving to minorities and lower social classes. This is quite reflective of what Jost and his colleagues describe in their research on system justification. As far as change goes, conservatives are less likely to be supportive of change. This is quite evident in the Tea Party, as seen in the following quote from Sarah Palin (a voice supported by many in the Tea Party movement): “Is this what their ‘change’ is all about? I want to tell ‘em, Nah, we’ll keep clinging to our Constitution and our guns and religion — and you can keep the change.” To conclude, while individuals may not fully understand their ideologies, humans are indeed “ideological animals”, as Jost and Hunyady (2005) conclude.
