Pieter -
My condolences on your experience trying to provide useful support to
(top) decision makers who might well not really want that help or
actually know what to do with it. It is quite familiar.
I moved from the umbrella of High Performance Computing to a (LANL)
division whose main thrust was providing scientific and technological
Decision Support Systems to the military/intell/agencies, just months
before 9/11. Doug Roberts (well known on this list before his death
a few years ago) and several others I worked with were tasked with
providing models and simulations of various aspects of the Post 911
context.
I remember distinctly when they went to DC to brief the White House on
how to handle the Anthrax Scare (remember when Bush & Cheney were
telling people to duct-tape the cracks around their doors in DC?).
The rough proposal was to give the bulk of the very limited stock of
Anthrax Vaccine to first-responders/military expected to have to respond
to/deal with possible Anthrax Incidents, holding back a fairly small
percentage to make available to those with "more clout than sense" who
might pull all the strings they had to make sure *they* were protected.
The latter was a well known feature of "those in power" and by making it
explicit in the models, there was less risk of having critical supplies
intercepted or mis-directed in an uncontrolled manner.
The models were based primarily on
mobility/transportation/social-network data from TransSims with
epidemiological (EpiSims was just emerging then). They were effectively
multi-scale models which at the base were ABM-like (the guy who had the
loudest voice insisted that the proper term was "sequential dynamical
systems").
I don't remember precisely what the administration chose to do but it
was quite clear that they entirely ignored the (somewhat well supported)
advice offered and did what they were going to do anyway. Had the
results in some way aligned with what they wanted to do, they would
surely have invoked the reputation of "the pre-imminent" national lab,
manhattan project, yadda yadda to support their acutely *political*
decision.
In retrospect, this was the "beginning of the end" for me. It was not
uncommon when briefing sponsors in DC for them to want us to provide
"answers"... their favorite Decision Support Tool would have been
something like an LLM today where they could enter any ill-formed
postulation/question they might be able to conjure and get back a
"yes/no" answer. They wanted crisp/confident answers to poorly formed
and under data-supported questions.
I often opened my briefings to such sponsors with "the answer to
*everything* is 'it depends' and our role with you is to help you fully
understand as concisely as possible *what* 'it depends' on and what
additional information you might want to collect to make it yet-more
useful/precise/salient". I can't say it was generally well-received,
but a very few folks would take me aside after such a briefing and thank
me for not "blowing smoke" the way most of our for-profit "competitors" did.
Proto-Palantir was on the rise in those days and I was so appalled then,
I can only imagine now. Add the hardware layer the likes of Palmer
Luckey/Anduril is developing for the likes of Thiel, et al. and you
have the ingredients for dystopian apocalypse?
No reason to believe that the likes of Tulsi/Kristy/Pete/BobbyJr will
use any of this class of "sensor fusion" and even more critically,
"effector fusion" for anything but the "greater glory" of their "dear
Leader".
I continued to work on projects in that domain after leaving LANL but
lost the last shreds of faith in their use as I watched how the ones we
delivered either got ignored or misused to support pre-existing
political agendas. My last work even vaguely in this domain was for
Renewable Energy projects
I hope/trust that those of you still working on such projects have more
reason to have faith in the way they will be used than I did by the time
I "punched out" (more emergency ejection seat than timeclock metaphor).
One last tedious Vaxx/AntiVaxx anecdote: My elderDotter who does
FlaviVirus research at OSU did her PhD studying Human Papilloma roughly
during the time that HPV vaccines were being promoted (mandated in some
cases). She was appalled at the public (political) conversation on the
topic, believing that the strategies put forward were a bit like the
"whack-a-mole" of early anti-biotic (mis)use.... possibly leading to
temporary reduced rates of cervical cancer (delayed by decades) but
followed by a possible/likely speciation/adaptation of the less virulent
strains (e.g. her own pet strain HPV 17). She also got pulled off her
Dingue work to work on COVID in 2020 even though she didn't have much
experience with Coronas (I guess Flavi's are a very different?) and by
shutting down much of their Flavi work, they lost ground.
Trump/RFKj threats against NIH/WHO/Vaccines/Infectious Diseases are
(career) existential threats to her, but she has compartmentalized well
so far, following Clemen's advice to "always read the news 2 weeks late,
by which time most of it will be known to be wrong and the rest
irrelevant". (I think I made that quote up, my own inner LLM
hallucination).
- Steve
PS... my rambling here is all mine, but I did (and almost always do)
consult various Internetty sources to try to align my imagination with
the facts of record... e.g. a bit of Palantir, HPV and Sam Clemen's
research...

I just want to add a personal reflection to my previous email
regarding the limits of scientific knowledge beyond cosmic
undetermination.
Throughout my career, I've seen the modeling of physical systems
through science and mathematics as a guiding light. Early on, I held a
view akin to Michelson's, believing that fundamental scientific
principles were largely settled. I knew about quantum physics, but I
thought it was more relevant to scientists than to engineers like myself.
My first significant challenge to this "science knows everything"
mindset came in the early 1990s when I read James Gleick's "Chaos". It
was unsettling; it felt like my professional worldview was being
shattered. Then, reading Stephen Wolfram's "A New Kind of Science"
inspired me to experiment with agent-based models (ABM), creating toy
models of real-world systems. Although I've never met him, I've been
greatly influenced by Joshua Epstein's work and philosophy,
particularly his notion that "you haven't explained it if you haven't
built it" (or something close to that).
About two years ago, South Africa faced a severe electricity supply
crisis with extensive load-shedding. Our national utility, Eskom, was
once world-class but suffered under corruption during Jacob Zuma's
presidency. Cyril Ramaphosa, who succeeded Zuma, made genuine efforts
to rectify the situation. I was informally consulted on how I might
advise the then Minister of Energy, Pravin Gordhan. Without
hesitation, I proposed building an ABM to understand the complex
dynamics at play and to simulate various remedial strategies. I was
then tasked with preparing a presentation and demo for the minister. I
worked tirelessly on this, but unfortunately, the meeting was
canceled, and no rescheduling occurred, leaving my proposal
undelivered. I often wonder what might have unfolded had the
presentation gone ahead.
Note, the message is my own, but since I'm very bad using the English
language, I use AI to assist my writing.

have certain global properties instead. But what justifies this
move? Given the theorem, we know this justification cannot be due
to any observational data we have collected -- even after allowing
for any local induction on such data. Perhaps one could appeal to
some strong form of global induction. For example, the Copernican
principle could be invoked which seems to modestly deny us a
special status in the cosmos: the observable universe is presumed
to be representative of the entirety of spacetime. But as the
philosopher John Earman has aptly remarked, "this seeming modesty
is belied by the immodest use to which the principle is put in
justifying an inductive extrapolation'' [9]. Indeed, induction on
such vast scales would seem to be suspect given that we are able
to observe only the tiniest fraction of the universe [10].
