Few of us do public policy on a daily basis, but many of us have opinions on it, and of those that don't most of us have friends that do. Not that having correct policy judgment buys you much in that context, consequentially speaking; I think the hedonic implications would probably end up being decided by how much you need to keep beliefs on large-scale policy coherent with beliefs on small-scale matters that you can actually affect nontrivially.

People that have little chance of ever actually doing public policy have virtually no incentive to have true beliefs about it and even if they did, they likely wouldn't get enough feedback to know if their heuristics about it are accurate.
