The context for the DEFUSE program is that SARS-cov-1 was of pretty significant concern that it could mutate into a global pandemic similar to the Cov-2 pandemic that actually happened. The program was funded to investigate, learn and prepare for what were predicted to be some of the more dangerous possible mutations.
The “smoking gun” here is all correlation. Saying “they predicted correctly what was dangerous and were proactively studying it” is not a good argument for causation.
However, the theory that I haven’t seen well debunked/studied is that improper handling/disposal of dead viruses/plasmids/etc. increased the risk of/allowed for recombinants with the endemic Cov strain resulting in those mutations of greatest concern… Have you come across anything on that?
“Doomerism” isn’t the issue. The issue is that kids are living through real shit and realizing that the adults around them are unable/unwilling to help/protect them when it’s needed. Your suggestion to fight “doomerism” is going to appear as a continuation of that and break any remaining trust even further.
Hope can be a useful tool, but within the context of American schools it’s more often a tool for gaslighting and control than meaningful change.
