Don't believe in randomness. "Random" means we don't understand what
determines it. Like "Junk DNA"; it's only junk up until we work out
what it's really for.
You can predict with 100% accuracy that systems with varying initial
conditions will bifurcate and become chaotic once driven beyond a
certain point. What you cannot say is what is determining the order in
the chaos once it arrives. That's closer to what I mean.

2 men start to dig a hole. They are instructed to make it reach a
depth of 5 feet. One of them murders the other with his shovel. Nobody
predicted that would happen. We can 'determine' the reasons for this
event only AFTER it happens, even though it was determined by
something that we might have noticed prior to the event if only we had
been able to. All action can be seen as logically determined in
hindsight. Before something happens is where we would like to be more
on top of things. Intelligence exists on terrorism but usually this
usually fails to determine our actions to prevent terrorist acts,
interestingly enough. If you look closely at what I am saying, it is
the rather messy human consciousness part of the equation that SPOILS
the mathematical modelling in most cases.  I am saying that a full
perceptual scan of the situation often takes us way beyond what the
data suggests. Just like the Mumbai massacre - intelligence WAS
available that suggested it could happen. Yet the massacre was
"allowed" to happen, because nobody could see the looming pattern in
the data until after it happened by which time it was bleeding obvious
to one and all. It seems that in many situations the sheer volume of
information available is as much a part of the problem as the decision-
making process. How do we decide? Data alone are incapable of making
decisions. You still need a wet, messy human brain with a perceptually
skilled mind to do that

Sure, but correlations occur between sets of data and there is a
tendency for them to look like causations. Most scientists and data
collectors are trained to say "correlations do not necessarily imply
causations" which is great advice up until the correlation turns out
to BE a causation

I would say that it is the premises - the starting assumptions that
are probably flawed, not the collection method, unless by collection
method we include the starting assumptions which are unavoidably
guiding the triage of the data. The biggest flawed assumption of all
is the belief that data collection of itself will give rise to ideas
and concepts. Data do not do that. We choose our starting points and
assumptions in all cases. Often we aren't even aware of these because
- well, they are assumptions and nobody really questions assumptions
much. Our way of looking at the data is not itself present in any way
in the data. I'm saying that if reality conforms to our model of it,
then the danger is we are looking at only a part of the situation. The
issue in question is the WHOLE situation, not just that part we CHOOSE
to look at. How can we ever be ccertain that we are in fact looking at
the whole situation. We only see what our assumptions and premises
allow us to see - we are blind to many things up until we get
clobbered by them

Hence my whole argument. I would say you are being somewhat kind!!

So why wasn't the "people situation" factored into the modelling? How
can we say we have a reputable model to go by when it explicitly does
not include the human problem? Answer: people only looked at the money
trail. The human foibles were not investigated until they suddenly
revealed themselves not as correlations but as causations. Even the
(rather humiliatingly) that he had been "too trusting of human nature"

No model of a situation is ever going to be complete if it doesn't
include the OBSERVER which is why I think my making an issue of this
is relevant to this list.

Exactly, but people like to think it does. Why we need "Lateral
Thinking" or "Possibility Thinking" or "Creative Thinking" to project
alternative futures and steer the present into the future by DESIGNING
ways around problems.

Mostly people just stand back and say "Well - if only that pattern had
been present in the data we would have seen it and would have been in
a position to act". That's nonsense. Usually we are completely BLIND
to the gravitating patterns in the data because our starting
assumptions don't allow that kind of clarity of sight

No - agreed. I am not "anti-mathematical" by any means. I merely
suggest that there are limits - very strong limits - to what we can
expect mathematical reasoning to achieve in the light of the chaotic
nature of human decision-making in a rapidly evolving (and
accelerating) universe. We may be the dream of numbers, but we cannot
use the numbers to predict how we ourselves might respond in a given
situation. You call that random - well, I am saying it is determined
by things we can only be conscious of AFTER events have transpired.

No data set can ever be the optimum model of a given reality - I don't
care what we are modelling.
