No, ideology is something you choose to believe even when reality conflicts with that.
I am only interested in what works for the most and reduces harm, I do not care about anything else.
And that, my friend, is an ideology. Your ideology. That normative standard is nothing that can be derived from reality. I believe the parent might disagree with it. I would only agree for a very specific definition of 'works for the most'. Ideology is the lens we see the world through. For a healthy person, it's an autofocusing lens, continually changing your perceptions of the world, and being changed by them.
Ideology is for children. In fact, the point of a lot of education is to give them a decent one. Is accepting progress 'natural'? Is demanding rationality 'normal'? Is compassion for the downtrodden 'admirable'? Each of these judgments depends on ideology. I hope our kids will be taught to answer yes to each of these, and maintain that ideology throughout their lives.
