An ideology is a system of abstract ideas in which theory determines evidence rather than vice-versa. It always involves a pseudo-religious adherence to some secular dogma. It is prevalent on both the political left (e.g. Marxism, the French Revolution and modern Woke ideology, in which gender and race are considered culturally constructed and therefore changeable) as well as the right (e.g. Randian Objectivism, where everything is interpreted according to rationalist capitalist ideology). One of the places in which it is particularly prevalent is in university education departments where constructivism is the dominant ideology and results in the rejection of the idea that students can learn passively under systems like Direct Instruction and in the dogma that a teacher shouldn't be in front of the classroom directing the learning. The ideology is so strong that they actively reject the findings of Project Follow Through, the largest study ever done on education, which supports directive teaching. This and others studies and meta-studies are irrelevant to progressives because they conflict with the inviolate dogmas of their ideology.
What I find a tad irritating is the habit of labelling others as ideological while treating oneβs own position as somehow *above* ideology.
That kind of self-exemption deserves a hard look in the mirror. Once we acknowledge our respective biases, we can have a good debate.
