Simulations, situations, voter happiness can range between 0 and 1.
Those values should be reachable in infinity like logistic function:
If negatives and positives balance each other, then function would end up very close to 0.5 after lets say 10 turns.
To reach <0.01 or >0.99 you would have to make sure that pushing in one direction is way stronger than pulling in other direction, essentially tug of war.
Some things would have higher inertia and others could have lower inertia - that is slowly/quickly reacting to sudden changes to input.
That is things should move like in molasses not like in vacuum.
