Does science tell when to shutdown?

Biden's claim that he would follow the science when deciding when to shutdown the economy is a shame and a shame. Don Boudreaux explains why science cannot tell us when to shut down. His reply to a reader echos what the WSJ posted earlier. Claiming otherwise denies the responsibility of authorities to consider ALL aspects of life, not just some statistics on coronavirus. I recognize that decision is difficult, in large part because uncertainty makes comparison of the costs and benefits difficult. I also recognize that the promise to "follow the science" may be a great campaign tactic because it contributes the narrative that Trump is anti-science. However, we need more clear and honest discussion of the costs and benefits of shutdowns, not pious, vague promises.
