Value #1 seems pretty at odds with 2 and 3, and dangerous with #5. I wonder how the CDC reconciles this... surely Be Right is more important than Be First. A spammy news site could claim most of these values in this order.
No, 2 includes "what is not known, and what is being done to fill in the gaps". Being honest about "we don't have an answer to this yet but are working on it" helps with the others.
The CDC had a special way of being dishonest here: They claimed and continue to claim there is zero knowledge available unless there are a dozen studies from the right institutions confirming it. This led them to be months behind on realizing that COVID was airborne.
it's really not complicated: tell the public as soon as possible what is known and be honest with them about what isn't.
#1 could be just opening up the communication channels and sharing where you are at with the rest.
