You mean like, “the trolley problem” doesn’t specify whether the single person on the spur is your child or not?

If the trolley problem is "Is it ethically permissible to pull the lever in the original Spur case", do you still think that?

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

In NM, this order allows boards/agencies to act more quickly to replace regulations that require ACIP guidelines with those relying on other sources of guidance. Something similar may work in some other states. But in some states, longer regulatory processes or even legislation may be required.
