This, this is what UCal Berkeley calls science:

Politically conservative agendas may range from supporting the Vietnam War to upholding traditional moral and religious values to opposing welfare. But are there consistent underlying motivations?

Four researchers who culled through 50 years of research literature about the psychology of conservatism report that at the core of political conservatism is the resistance to change and a tolerance for inequality, and that some of the common psychological factors linked to political conservatism include:

- Fear and aggression
- Dogmatism and intolerance of ambiguity
- Uncertainty avoidance
- Need for cognitive closure
- Terror management...

Concerns with fear and threat, likewise, can be linked to a second key dimension of conservatism - an endorsement of inequality, a view reflected in the Indian caste system, South African apartheid and the conservative, segregationist politics of the late Sen. Strom Thurmond (R-South S.C.).

Disparate conservatives share a resistance to change and acceptance of inequality, the authors said. Hitler, Mussolini, and former President Ronald Reagan were individuals, but all were right-wing conservatives because they preached a return to an idealized past and condoned inequality in some form. Talk host Rush Limbaugh can be described the same way.

This research marks the first synthesis of a vast amount of information about conservatism, and the result is an "elegant and unifying explanation" for political conservatism under the rubric of motivated social cognition, said Sulloway. That entails the tendency of people's attitudinal preferences on policy matters to be explained by individual needs based on personality, social interests or existential needs...

The researchers conceded cases of left-wing ideologues, such as Stalin, Khrushchev or Castro, who, once in power, steadfastly resisted change, allegedly in the name of egalitarianism.

Yet, they noted that some of these figures might be considered politically conservative in the context of the systems that they defended. The researchers noted that Stalin, for example, was concerned about defending and preserving the existing Soviet system.

Nazis. Stupid, avaricious, unintelligent, arrogant, pathetic, intolerant, childish, overpaid, underqualified, mentally retarded Nazis. That's the only order of being, the only manner of beast that could come up with as monumental an act of hypocrisy as this. This is the only perversion of humanity that could conjure up this monument to ideological hubris that makes the very word "Orwellian" superfluous and redundant. That could create such a blatently politicized, such an obviously ideological, such an openly hateful, intolerant, and violent screed and yet have the unmitigated gall to claim that it consists of objective, scientific findings. That could be so blinded by self-righteous narcissism that they have actually deluded themselves into believing that they are merely engaging in objective analysis. That could actually believe that their personal, partisan political ideology is, by startling coincidence, proven to be the only scientifically correct one for a healthy person to hold. Liars, hypocrites, charlatans, Leftists.
