This episode covers topics such as forecasting, maritime archaeology, and the importance of diverse information sources. Dr. Tetlock's concept of perpetual beta is discussed, emphasizing the need for adaptability in thinking.

The guest shares their academic journey, transitioning from applied physics to international studies, anthropology, and archaeology. They highlight their experiences studying in various countries, including Norway, Scotland, and Ireland.

Key discussions include the approach to forecasting, where the guest uses GIS mapping to analyze geographical issues. They stress the importance of not relying on a single source of information and the value of being open to new ideas.

Additionally, the guest talks about teaching their sons to think critically about problems, encouraging them to consider multiple factors when answering questions.

The episode emphasizes the need for continuous improvement in models used for forecasting and archaeological research, advocating for a mindset of constant learning and adaptation.

TLDR

Dr. Tetlock discusses forecasting, archaeology, and critical thinking in information analysis.

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