Mark Twain
is famous for saying that "it is difficult to make predictions, especially about
the future." My mother often predicted that I would become a bum. She was right. As a happily retired guy I am
sure that Betty would agree with my mom’s vision.
Predicting
the future is both necessary and humbling. Squirrels don’t have spreadsheets
and mathematical models, but they gather nuts in anticipation of the coming
winter. The playboy squirrels who don’t predict so well lose a lot of weight after winter arrives. Clearly we learn
from squirrels and we predict lots of things that improve our lives. But
predicting the future is not an easy thing since the future by definition is
unknowable. Those who take actions in anticipation of a specific future often
make mistakes – sometimes very damaging ones.
Yet we
predict and forecast. I grew up in Florida. During hurricane season we all
become forecasters. Will that storm turn into a hurricane? Will that hurricane hit
land? If so when will it hit? Where will it bring the most disastrous
winds and lightning? Weather forecasters are almost always wrong when it comes to predicting these critical facts about hurricanes.Maybe that is an extreme example but I don’t think
so. We modern folks with our math and models forecast a lot of things. It is
important to do so. And we do so knowing that we are often wrong.
If you are
still awake your mind might be wondering and thinking about all the ways we
predict the future. My reason for writing today arises because of what I see as
a very inconsistent approach by our present leaders with respect to forecasting
some very important things.
The Obama
administration is VERY sure that climate change is coming and that without
major policy changes and a lot of investment, we and the rest of the world will
be threatened. I think he said that climate change is our most important future
challenge. There are some very important people and very sophisticated models
supporting the urgent need to spend trillions of dollars to change and prepare
for things that will happen in the distant future – some expected to arrive more than 50
years from now.
Despite the
fact that the future is hard to predict and despite the huge sums of money
involved, the president is laser focused on attending to these challenges
immediately. In his and his supporters’ minds, this expenditure is worth the
risk. His policy makes us all invested bettors on future climate.
Compare this
aggressive approach to another important future challenge –
nuclear weapons. The world is already in accord that countries will not produce more nuclear
weapons. And that accord is for good reasons. While it seems highly irrational that any nation, even a rogue nation, would fire nuclear weapons at another
country, we worry that all nations are not always rational. It is like the idea
of someone yelling fire in a crowded movie theater. It seems quite irrational
to yell those words – yet we have laws to prevent crazy or mean people from
doing such things. The world has agreed to control nuclear weapons for similar
reasons.
Yet the same
administration that worries about climate change wrecking our countries is
willing to predict that Iran and North Korea can be trusted to not yell fire in
a crowded movie theater – or to not unload a nuclear weapon on one of the rest
of us. Obama can vividly see water levels rising and shorelines being over run
despite knowing that all this future information is model-driven and about the future
50 years from now. Yet the same Obama cannot imagine a religious zealot or a desperate
dictator shooting a nuclear weapon. He cannot see those countries most threatened by nuclear Iran and North Korea arming themselves. He seems to minimize any real threat from a world with increasing amounts of nuclear weapons in the most unstable places.
Kerry and Obama repeatedly say that the recent accord with Iran will
prevent them from obtaining a nuclear weapon yet they also agree that within 10
years Iran will be able to manufacture such weapons freely. They publicly agree that after those 10 years it will take only one year to be ready to aim and fire. So why are we not aggressively trying to prevent that outcome? My
grandson Nolan will not be 13 yet in 10 years. I am not particularly crazy
about him having to worry about Iran or North Korea or some other despotic place. Clearly this is at least as important as the impacts of climate change on him. Right?
So here is
my question. In the case of global warming, President Obama is willing to
forecast the absolute worst. In the case of Iran and North Korea his “models”
assume the absolute best. Most economic forecasters that I know (who are not
ideologically motivated) bring a “show me” attitude to forecasts. They are
always skeptical about their model’s predictions. They always discount the
certainty of what we think we know. They always follow their forecasts with a
list of caveats longer than a drug company’s list of side-effects in a television commercial.
Why is Obama
so sure about the intensity of climate change and so sure that Iran and North
Korea will turn into the cutest and sweetest puppies? Why can't we apply conservative and consistent forecast approaches to policies related to climate and national defense?
