Exactly.That is certainly true. Clear metrics would be wonderful. If they said, “we can remove mask mandates in schools once 70% are vaccinated,” you’d see shots in arms. And we know enough to know if we hit that level, society can function and hospitals won’t be overrun.
We can not aim at a target that does not exist.
We need a goal.
A person who says I want to lose 5 pounds is much more likely to take action that a person who says I need to lose some weight.
Yes they are both goals but one is more clearly defined and therefore more likely to be acted upon.
