I don't believe in free will. I haven't really for about 20 years or so. However, I act as if I do, as I've always done. It's a habit I choose not to break. Changing to act as I believe would be too much for me to handle. I would need to rethink pretty much everything I do. It's a completely different set of axioms in every domain of human knowledge, ethics, behaviour and interaction.

I don't think I'm raving mad, but perhaps because I don't act on my beliefs, I don't fit your conditions?

However, I do believe the justice system would be better run with this in mind.

Not that I agree with your premise, but why would you personally adopt a cognitive dissonance? A healthy mind is generally regarded as satisfied with itself as it is free of self-contradictions.

I think behaving as if there is no free will is such a change from how I was raised and how 99.99% of society believes and functions, would require some Buddha-level strength of will, which I don't possess.

It's so different than all the constructs we've created, you can kind of throw "generally regarded" out the window, frankly :) (don't mean that to sound harsh if it does). All of psychology would need to be rewritten. By me? I guess?

The 3rd option is to try and convince myself of what I regard as a lie (that we have free will), which is also difficult, but probably easier?
