Maybe it'd be better if central banks weren't given exact targets? Say targeting inflation at, say, 1-5% would be better.
If you target 1% and you screw up your policy you might go below 0%, which is a big no-no according to modern economics and CB policy.
The actual big question which none of the CBs want to answer is whether deflation would necessarily be bad today. Modern CB discussion on deflation is basically "Great Depression bad" and "Look at Japan".
