Liberal and conservative are 1) psychological profiles from which emerge 2) moral sentiments or intuitions, and 3) value systems, or sets of principles of governance.
The first two of these are real and should be respected. Every individual deserves their dignity.
The third should be subjected to critical inquiry of the sort described by Popper, or by Jonathan Rauch in Kindly Inquisitors.
Our problem is that we conflate all three as one and the same, and we allow 1 and 2 to trump 3.
This is anti-science, anti-evidence, anti-critical-thinking, and anti-rule-of-law cognitively distorted thinking.
The road to hell is paved with moral sentiments that are allowed to overrule the value system of liberty, which is:
Process-based negative liberty, justice, equality, and fairness – aka the rule of law – and the separation and distribution of government power.
Antithetical to which is the value system of outcome-based positive liberty, equality, justices, and fairness – aka the rule of man – and the consolidation and concentration of government power..
The former of those value systems is that of conservatism and of the Constitution, the latter is that of liberalism.
The value system of liberalism, as opposed to its psychological profile or its moral sentiments, is antithetical to the value system of liberty itself, rightly understood; which is to say, to America.
Conservatism sees and thinks multi-dimensionally, liberalism thinks linearly.

Thesis Part II, Liberalism and Conservatism are NOT like Yin and Yang, they are like Flatland and Spaceland:
Thesis Part III, Liberalism thinks abstractly and linearly, Conservatism thinks empirically and holistically

Moral Foundations Theory Helps to Explain Cognitive Complexity
Liberalism is Moral Immaturity, Conservatism is Moral Maturity
Conservatism is wrong in the very same way that Liberalism is wrong. Both are linear, one-dimensional ways of looking at a problem. Both replace objective observation and analysis with dogmatic assumption and pre-determined conclusions. This is the opposite of what Popper preached.
By adopting the right-left paradigm, you are limiting yourself to linear world view of liberal vs conservative and ignoring all of the solutions that do not fall on that narrow line of demarcation. Once you take this approach, you now subject yourself to all of the many cognitive distortions that narrative bias entails as psychology and cognitive neuroscience has cataloged over the past 50 years.
Don’t take my word for it, look at Popper’s own warning:
“Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.” Objective Knowledge: An Evolutionary Approach (1972)
