00:00:08
I've always had the interest and when I
00:00:11
first
00:00:13
I started a bunch of things I was one of
00:00:15
these constantly changing your majors
00:00:16
people and I changed between applied
00:00:18
physics is where I started and then I
00:00:21
went to international studies but then
00:00:23
somehow transitioned to anthropology and
00:00:26
archeology but I always kept the
00:00:28
interest up in international studies so
00:00:30
kind of went from wanting to study
00:00:31
current cultures Mo's going on to
00:00:33
studying past cultures and what was
00:00:36
going on there and that the constant you
00:00:41
know urge to learn more about all
00:00:42
societies kept me interested in
00:00:44
forecasting in what was going on in
00:00:46
different countries and as I said by
00:00:49
switching all the time i went to quite a
00:00:51
few different universities in quite a
00:00:53
few different countries i was at school
00:00:55
in the stars beginning utah followed by
00:00:59
vermont and then norway then back to
00:01:02
utah and i finished my doctorate in
00:01:03
Scotland where I was there for seven
00:01:06
years and then I went to Ireland for 10
00:01:08
years so you know constantly moving in
00:01:10
different cultures dimmer societies
00:01:11
different political systems it was
00:01:13
always something of great interest to me
00:01:18
in what I do for my day job in maritime
00:01:21
archaeology it's a very similar thing we
00:01:24
take the outside view we have very
00:01:25
disparate information we have maybe a
00:01:28
few artifacts maybe not even maybe some
00:01:31
historical sources maybe someone
00:01:34
stumbled upon something and just have
00:01:35
rumors historical studies ethnographic
00:01:38
studies and we have to take all this
00:01:40
information and try to piece it together
00:01:41
to come up with a solution to or
00:01:44
explanation of what we're finding and
00:01:46
it's very similar in forecasting I kind
00:01:49
of approach it the same way where I'll
00:01:51
take very disparate information um I
00:01:54
won't take the big huge pictures that
00:01:57
are thrust in your face I'll take
00:01:59
outside of use and use some of the same
00:02:00
tools that I use at work I'm a huge
00:02:02
proponent of using GIS mapping of
00:02:05
different issues to try to get like say
00:02:08
it's a question that has a geographical
00:02:09
perspective I'll make my own GIS program
00:02:12
and basically you know put the model
00:02:16
together that has all the contributory
00:02:17
information from different press sources
00:02:20
different mapping where different roads
00:02:22
are communication routes transportation
00:02:24
routes and it's the same kind of thing I
00:02:26
would do in archaeology I just apply it
00:02:28
to the future and forecasting as opposed
00:02:30
to applying it to the past
00:02:36
the first one was there there's almost
00:02:39
no but I'm I'd say there's no nothing is
00:02:41
certain that's not entirely sure there's
00:02:44
I'm sure there's certain things that are
00:02:45
sir but for the most part nothing is
00:02:48
certain the other thing was don't trust
00:02:51
one source of information but then don't
00:02:53
discard all sources just because you
00:02:55
think it's not valid when you're
00:02:58
whenever you're reading a source of
00:02:59
information if you have just one single
00:03:00
source and is the only one saying it I
00:03:04
didn't sometimes I wouldn't dismiss it
00:03:07
but I would not trust it I'd look for
00:03:09
something that would you know contribute
00:03:11
to it or just help verify it and that
00:03:14
can even be one of these sources where
00:03:16
you know you see it on the intern you
00:03:17
think wow that's really dubious these
00:03:18
guys are you know pretty crazy but
00:03:20
somewhere in there if you read through
00:03:22
the whole thing there might be one
00:03:23
sentence which collaborates what's going
00:03:25
on in that other source that was a
00:03:27
single source and I was like okay now
00:03:28
I've got two independent sources so and
00:03:31
you can start to build on that um so one
00:03:33
of the things that would have says don't
00:03:35
rely on the one don't discard sources
00:03:38
just because you may think they're a bit
00:03:39
out there and there are quite a few
00:03:42
sources that are out there
00:03:47
trust yours
00:03:48
self but doubt yourself as well and
00:03:50
always be prepared to be devil's
00:03:53
advocate to yourself if you're working
00:03:55
within a team that's even better because
00:03:58
most forecasters do not have a problem
00:04:00
being devil's advocate or we call red
00:04:02
teaming and keep an open mind don't go
00:04:06
into something thinking you know exactly
00:04:08
what's going on it never seems to work
00:04:10
out that way just when you think you
00:04:13
know exactly what's going on it changes
00:04:15
it'll be the main thing is just you know
00:04:18
be open to change in dr. tetlock spoke
00:04:21
he mentions that were in perpetual beta
00:04:22
that is a great way of thinking of it is
00:04:25
always be willing to change and learn
00:04:27
and just you know go with it a lot of
00:04:30
people get really kind of stuck in the
00:04:31
mud on certain ideas and that's that's
00:04:34
the quickest way to get it wrong
00:04:39
like I said I go back and forth between
00:04:41
the different you know venues of inquiry
00:04:43
in archaeology and in forecasting so
00:04:46
there has been times were one of the
00:04:48
things that forecasting told me is it's
00:04:50
great if you have a model but all there
00:04:52
can always be a better model always be a
00:04:54
better model you might have one that's
00:04:55
showing you exactly what you want but
00:04:58
you know if you tweak it a little bit or
00:04:59
you say you find a new data set can
00:05:01
always be that little bit better and
00:05:03
I've started to apply that to some
00:05:04
shipwreck hunts that I've been doing
00:05:06
where we have a model on how to locate
00:05:08
shipwrecks in areas of high probability
00:05:10
but it can always be better so I've
00:05:13
actually started tweaking some of the
00:05:14
models that I use at work to add
00:05:15
additional data sets maybe pulling
00:05:18
things from multidisciplinary studies
00:05:20
from geomorphology marine geomorphology
00:05:24
riverbed hydrological processes going
00:05:27
into shipwreck site formation and just
00:05:29
basically in a constantly tweaking the
00:05:31
models um there's something the other
00:05:33
thing that I've tried to do as much as I
00:05:35
can as I have two young sons who I'm
00:05:38
trying to teach them how to approach
00:05:40
different issues you know not not so
00:05:43
much to get him in trouble at school for
00:05:44
questioning the teacher all the time
00:05:45
which is very possible but when they
00:05:48
answer a question say well is that it I
00:05:50
spoke to my son about a tree growing in
00:05:53
a field and so how much do you think
00:05:53
that tree is going to grow next year and
00:05:56
you just said oh well this I said why'd
00:05:57
you say that he's like well because just
00:05:59
looks like well did you think about how
00:06:00
much is it gonna rain next year how much
00:06:03
fertilizer is the farm are going to put
00:06:04
in that field without trees in the
00:06:05
middle how often is he going to plow it
00:06:07
but you know there's so many issues that
00:06:09
surround one issue that when you hear
00:06:12
one question there's usually you know 20
00:06:14
30 however many more questions that can
00:06:16
help you answer that question so I've
00:06:18
been trying to push it on them to kind
00:06:21
of think that way
00:06:39
you
