Scientists Should March

Scientists are planning a “March for Science” in Washington, DC and many other cities on 22 April 2017. Some commentators seem to think this is a bad idea, because it would politicize science.

Before I continue, let me suggest the form an intellectually honest debate about global warming would take:

Scientists:

Global warming is happening.

It will cost $X to stop and/or mitigate global warming. If we do not stop and/or mitigate it, it will cost $Y to deal with the resulting property damage, logistical problems, loss of standard of living, food supply shortages, disease outbreaks, and security threats. $Y is much bigger than $X.

Democrats:

Okay. We think that from an economic, social, and security standpoint, we would be better off paying the smaller amount up front, $X, than having to deal with all those problems individually later on.

Republicans:

Okay. We think that the impact to certain market sectors would be too great to pay the $X up front. We think we are better able to pay installments of the larger cost $Y later on, as those various problems crop up.

Now, allow me to summarize the form the actual debate about global warming seems to be taking in the United States:

Scientists:

Global warming is happening.

It will cost $X to stop and/or mitigate global warming. If we do not stop and/or mitigate it, it will cost $Y to deal with the resulting property damage, logistical problems, loss of standard of living, food supply shortages, disease outbreaks, and security threats. $Y is much bigger than $X.

Democrats:

Okay. We think that from an economic, social, and security standpoint, we would be better off paying the smaller amount up front, $X, than having to deal with all those problems individually later on.

Republicans:

Global warming is not happening.

Scientists:

But we just told you that it is, and presented our evidence, and told you the cost of ignoring–

Republicans:

Stop doing science.

It’s easy to say that scientists should keep themselves in the business of producing scientific evidence and scientific conclusions, and stay out of the business of figuring out how to act on those conclusions. Science, after all, doesn’t tell us anything about morality or ideals, it just describes what happens in the world.

What does someone do, though, if they hold a particular position, and science produces definitive evidence suggesting that their position does not give them the result they want? In my field of engineering, the correct response to this scenario is to redesign my system so that I do get the result I want. I have to trust that the most up-to-date scientific theory is the most accurate description available of how my design will actually work, regardless of what I want my design to do. However, more and more, we are seeing a different strategy emerge in the field of politics: attack the science itself. Cast aspersions on the scientists. Talk about presenting “alternative facts,” as though physics behaves differently depending on one’s ideals. Cut off the ability of scientists to conduct their work, if one thinks that they will uncover evidence disfavoring one’s suggested course of action.

This is not a good way to solve problems.

What I believe scientists are standing up for in their march is simply the idea that decisions should be based on evidence. Conclusions should be based on a strong argument. Engineers know this. Businesspeople know this. Doctors know this. Scientists know this. Politicians should, too.

Scientists may not be perfect people, and an individual scientist’s conclusions may not be completely correct. Lots of factors feed into this: the tenure process, aggressive university publishing policies, limited funding, and severe competition leading to hype. But that is why we conduct science as a community, and as part of a larger iterative process. Scientists as a whole are always improving the state of knowledge. Others follow to correct and refine previous knowledge. As such, the current state of the art does represent the best available scientific description of the world. And, in many cases, that description has been converging. So, I can say with confidence: Global warming is happening, and human-caused, and has real economic costs. Vaccines don’t cause autism. GMOs are fine to grow and eat. The collapse of the bee population is going to cause big problems for agriculture. Coal power is just more expensive than natural gas (and, soon, wind and solar). Tax cuts for the wealthy are not as effective at stimulating the economy as government investment. No refugee from the Middle East has committed a terrorist attack in the United States. American police shoot black people at a disproportionately high rate. These are all things we can measure, facts based on evidence. There are no alternatives.

What do we do about these things? Do we do anything about them? Yes, those are questions for politicians to debate. But I can tell you this definitively: cutting off support for the science that produced evidence of a problem does not make things better. Politicians who advocate doing so are not going to help solve those problems, and we all need to remember who they are and how they are exacerbating our problems.

That is why scientists should call attention to their work and to their efforts. They need to remind everyone that evidence matters and decisions based on evidence matter. They need to remind people that experts have expertise. This march is not just about science, it is about the very idea that we can observe the world and use our observations to inform our expectations about the future. It’s about stating the reality of reality as opposed to “alternative facts.”

The idea that scientific evidence is a description of reality is not a political statement. I can understand how that might be hard to grasp, though, for a party whose paragon once took an incorrect position and said, “my heart and my best intentions still tell me that’s true, but the facts and the evidence tell me it is not.”

Guess what? The facts and evidence were right.

We Can’t Grow Forever – so What?

Two interrelated opinion pieces appear in today’s New York Times. The first is an essay by David Brooks about how the economic growth of the 21st century compares unfavorably to that of the heady 20th century. The second is the Editorial Board’s argument that data does not support the idea that automation is responsible for recent economic malaise.

Brooks’ piece resonated with me because I hold the opinion that, regardless of your position on regulations, taxes, the environment, or public policy, a nation simply cannot grow forever. Whether we are talking about population size, economic output, available resources, or territorial holdings, there is simply a fundamental limit to what is available on the Earth. I think we are starting to see these limits reflected in our growth path, as Brooks writes. Extractive industries provide a good case study: I don’t think we’d have deep-water drilling if shallow-water drilling remained lucrative, and I don’t think we’d have the economic case for fracking if the easy-to-reach resources were still as worthwhile to get. Similar principles are going to apply to any resource or population.

The notion of the Earth being finite seems to bother economists. If our population does not continuously grow, then our output doesn’t grow. The United States’ trajectory through the 20th century was predicated on the idea of continual growth, which spells trouble if we try to carry that path forward. This is where the editorial comes in: In order to succeed and provide for our citizens in the 21st century, we need new policies.

The United States’ economic policies over the last several decades have been basically Republican policies. (I want to explicitly draw a distinction between “Republican” policies – across-the-board tax cuts, cutting regulation, and increasing defense spending – and “conservative” policies – market-based solutions, revenue-neutral ideas, and the like – because they are very much not the same.) Somehow, the Republican party has managed to sell themselves to many Americans as the small-business-friendly, growth-promoting, income-increasing party that they are not, instead of the giant-multinational-conglomerate-favoring, uber-wealthy-CEO-catering party that they are. In a world where more and more people are gunning for fewer resources than they could have a half-century ago, those policies may be the exact opposite of what we need. So are we going to get the policy reforms we need under Republican leadership? Certainly not. My generation is going to inherit a world of rapidly rising income inequality (not to mention sea levels).  Because, I think people wanted to buy one thing when they elected Republicans last November, but they got a lemon.

The frustrating thing to me is that I believe the Democrats have it right, in terms of policy philosophy. Maintaining a strong economy in the future world is going to be about efficiency. We’re going to have to find new ways of going about our business so that we can make more with less. We’re going to have to find ways to incentivize building robust products that last a long time, instead of selling consumers on the idea of constant upgrades. We’re going to have to find efficient ways for society to reduce its overall costs while balancing individual needs, like all buying health insurance so we don’t pay more at the ER. We’re going to have to power our homes with home-grown renewable energy, not just because it’s good for the planet but because it’s going to be cheaper and more readily available in the long term. We’re going to have to go back to what we learned in elementary school: reduce, reuse, recycle!

And we’re going to have to figure out how to make economic growth out of that, as our population starts to shrink. That clearly requires policy changes. Blind cuts to regulations so that we can dump pollution in rivers won’t solve this problem; tax cuts that go mostly to wealthy corporate boardmembers won’t solve this problem; more nuanced approaches are needed. The solutions are likely carefully crafted, market-based plans involving a full portfolio of cuts, new regulations, and taxes.

Many of those will be conservative solutions.

(Probably, at this rate, ones put forward by the Democratic Party, like the ACA.)

A ray of sunshine here: At the state and local level, politicians are trying to solve problems. This involves recognizing what the problems are, and trying to implement a plan to address them. It also involves trying a new plan when the first one doesn’t work.

So, let’s watch carefully over the next few years: What works? What doesn’t?

And who put forward which ideas?

Donald Trump will fail as President, but we must still resist him

Donald Trump will fail as President.

Let me explain that statement a little, by defining what I mean by “fail.” Trump will fail to accomplish most, if not all, of the goals that he has publicly stated he wishes to accomplish. (He may, of course, accomplish goals that he has not publicly stated, like enriching himself by manipulating the office of President or severely curtailing civil liberties. But we can’t really know what those are, so I will leave them aside for now.) The reason is simple: most of his stated goals are flatly impossible.

Take, for example, his pledge to “unleash” the coal industry. He plans to do this by rolling back Obama Administration regulations. However, those regulations aren’t the reason why the coal industry was in trouble in the first place. Coal was in trouble because it’s too expensive. Natural gas is cheaper. Even wind and solar are getting cheaper than coal! The only way to “unleash” coal would be through a massive campaign of government subsidies. Good luck getting Paul Ryan to sign up for that, Mr. Trump!

Or, for another example, look at Trump’s vow to put the US military “on display” by increasing the military budget to buy more ships, tanks, and planes. But the military development and procurement processes these days are decades long – so even if Trump doubled the military budget, it could be ten or twenty years before there’s any visible increase in American military capability!

Trump also says he wants to bring manufacturing jobs back to the United States. He wants to do this by renegotiating free trade agreements. This won’t work at all, though – the reason why lots of manufacturing jobs dried up in the US is more because of automation than trade and jobs moving overseas. A terrific example is the Carrier plant where Trump claimed to save jobs from moving to Mexico. Part of the large taxpayer-funded incentive package Trump gave to Carrier was assistance investing in their Indiana plant. Guess what Carrier is investing in? Automation! If that automation cuts the need for more jobs than Trump saved, he produced a net loss for American workers.

I could go on, of course. There’s the infamous travel ban that doesn’t target terrorists, but instead targets terrorists’ victims. There’s his pledge to provide healthcare for everyone, which there’s really only two ways to accomplish: give it to everyone (a single-payer system), or require everyone to get it and give them assistance if needed (Obamacare). His promises regarding GDP growth or budget-balancing don’t square with any projections, assuming he cuts taxes the way he promised. His rhetoric and stated goals are populist, but his policy proposals and cabinet appointments are corporatist. A wall along the Mexican border will have to traverse rugged mountains and sovereign Native territory, and there is no way for the US to get Mexico to pay for it.

He’s simply not going to do any of the things he wants, because he cannot. But I think patriotic Americans need to fight against him whenever we can anyway.

The first reason to resist Trump is because, though he may be a snake oil salesman, he’s a good salesman. He knows how to use your own brain against you. His administration appears to be on a concerted campaign to gaslight us – to get us to question the veracity of any information presented to us by anyone other than the administration itself. They invent fake terror plots, fake definitions of words, fake counts of people, fake reasons why the President can’t disclose his business dealings, and fake historical events. This process isn’t benign, and it is insidious. Removing references to Jews from the Holocaust, for example, has long been an anti-Semitic tactic.

So, we must constantly be on our guard. We cannot assume that the administration has our best interest in mind. We cannot even assume that what they say is accurate. We have to carefully screen their statements against facts available from reliable sources, and we have to defuse their gaslighting with knowledge of how they are trying to manipulate us. (Seriously, read that article!) We have to resist. If we don’t, who knows what they will try to sell us on?

The second reason to resist Trump gets back to my definition of failure as failing to accomplish his stated goals. I am quite sure that Trump has unstated goals. If he didn’t want to hide anything, why would he keep insisting against disclosing his tax returns, for example? Unfortunately, there’s no way to know for sure what those unstated goals are. But we can probably get some idea by looking at the stated goals of his closest advisers. Steve Bannon, for example, apparently said that he wants to bring the entire American system “crashing down,” and he has been explicit about his desire to curtail civil liberties, especially for non-whites and non-Christians.

Even if Trump fails to do the things he campaigned on doing, he can do a lot of fundamental damage to civil society in the meantime. The confusion over enforcement of the Muslim travel ban illustrated perfectly how, even if the Administration’s orders are unconstitutional, unethical, and flagrantly immoral, they could ram them through for some time before the courts could catch up. (The legislative branch of government has yet to do so!) Voting restrictions on minorities or the poor, more travel restrictions, profiling by law enforcement, permit and grant awards, and other avenues allow the executive branch of government a great deal of power. Therefore, we must fight back: we must challenge his orders in the courts as rapidly as Trump signs them, we must pressure our representatives to stall Trump’s legislative agenda and restrict executive power where it’s abused, and we must remember to keep our voices heard in all spheres of government. Remember, Trump lost the popular vote, and his electoral college victory hinged on the votes of 0.025% of the population – in an election when less than half of voters actually cast ballots. He has no mandate. His Republican allies’ mandates rest on gerrymandering. With such a weak base of support, there is an opening for us. We must seize it.

For the sake of all those too weak to fight back, all those who would be victimized by Bannon’s place on the National Security Council and Trump’s executive orders, we have a moral, ethical, and patriotic obligation to fight back. Because although Trump will fail, his failure cannot come soon enough for our communities.

A brief note about the 2016 presidential election

Hey, Americans. I want you to know that I’m looking for a few things from my national leadership, especially the President.

  1. Infrastructure investment. Doing this is how we will solve a huge number of problems: Want to create jobs? Advance American science and technology? Mitigate global warming? Fix broken bridges? Make the electric grid more robust to cyberattack? Then we have to invest in our highways, power systems, public transit, National Science Foundation, NASA, and data systems. This all takes concerted national effort and a lot of money, but the important thing about it being an investment is that the payoff is greater than the cost!
  2. An end to the attitude of constant warfare that has pervaded American foreign policy since World War II. Most, if not all, of the foreign policy challenges America faces today are of our own making. We need to stop doing that! We could also save a ton of money in the defense arena. I’m convinced that the US Department of Defense budget could be half of what it currently is, and the US would suffer no loss to national security. (In fact, ending some of our more specifically provocative programs like drone strikes, prompt global strike weapons, or the recently unveiled B-21 would probably increase our national security, by de-escalating arms races and conflicts.)
  3. A considered, logical, and data-based approach to solving our pressing problems. Issues like income inequality, racism, campaign finance reform, education, the national debt, immigration, foreign policy – or anything else, really – cannot be solved with a simplistically soundbyte-y ideologies like “build a wall,” “create jobs,” or “bomb them.” They are complex, multifaceted problems, and we know from history, science, or economics which solutions are more likely to work and which are not. We should use that knowledge. To give an example, if we want to reduce the incidence of gun deaths, studies show that the most effective way to do so is to reduce the rate of gun ownership. To give another, global warming is definitely a thing, definitely caused by humans, and definitely going to threaten our lives and livelihoods in the future: we should fix it, and we know how. In some way, a reduced role for ideology may help advance the other two points, too.

It would be nice to see more of these perspectives from the campaign trail. None of the Republicans have any interest in any of my points. Most of them actually seem to take opposite positions; to listen to their debates, I guess America needs less investment, more war, and more ideology. On the Democratic side, Hillary Clinton seems to be interested in items 1 and 3, while Bernie Sanders seems to like them all. If only Congress had more adherents to these ideas!

What is the nature of the STEM crisis?

There is a recent National Science Foundation report out that says, over the decade from 1993 to 2013, the number of college graduates in science and engineering fields grew faster than the number of graduates in any other fields. By 2013, we got up to 27% of college graduates getting their degrees in science or engineering. Hooray! STEM crisis solved, right?

I actually see something in this report that I find quite worrying, and a sad commentary on the state of science and engineering in the United States.

The report says that only 10% of all college graduates got jobs in science or engineering fields. That statistic means that, although 27% of our graduates are in STEM fields, at least 17% of graduates got their degree in science or engineering but couldn’t find a job in any scientific or engineering field. Put another way, at least 63% of STEM graduates couldn’t get a job in STEM fields!

The STEM crisis, in my opinion, isn’t about the number of graduates. It’s about the support our country and society gives to science and engineering. Our government has forsaken basic research in favor of maintenance-level defense tasks and austerity. Our companies have forsaken applied research in favor of “killer apps” and next-quarter profits. In light of those actions, it’s no wonder that we’re now worried that other nations might leapfrog us technologically.

If we want to get out of this hole we dug, we need to dramatically increase our support for science, engineering, and innovation.

Vhonn/Brawn (what could we do?)

Vhonn/Brawn

Wernher von Braun is one of the lions of the early American space program: a pioneer who engineered our initial forays into orbit, our steps onto the surface of the moon, and our designs for space stations and Martian colonies. He developed or directed the development of the technology to enable those feats. Without him, the United States might not have a space program as we know it.

But all technology is only as good as the people who use it. If von Braun had a personal failing, it was being willing to embrace the use of his devices for nefarious purposes, so long as he could work on them at all. His part in aerospace history began in Nazi Germany, with slave labor and vengeance weapons. Then, after he surrendered to the Americans, he secured a place at the US Army not by promising it the moon – but by promising it the intercontinental ballistic missile. The dual use of this technology was not lost on von Braun. As he famously said of the V2, “the rocket worked perfectly except for landing on the wrong planet.” Since then, every single government to come into contact with von Braun’s work has first thought not of space exploration, but of ballistic missiles armed with weapons of terror.

Brawn

Two worlds. The reckless denizens of Brawn choose to use their technology for destructive ends. In their insecurity, they ultimately realized their driving fears. Now, all that remains of them is technological detritus: shattered pipelines, broken chain-link fences, and cracked bunkers; all are monuments to warnings ignored.

Vhonn

On another world, the policymakers kept their engineers focused on exploration, enriching and enhancing their culture. They ultimately landed an expedition on the neighboring planet Vhonn – a place harsh in its alienness, but full of scientific treasure troves, including keys to understanding life as they knew it. Their citizens are confident and inspired. They strive forward into the cosmos, and will eventually stake claims throughout their star system.

Today was once celebrated as Armistice Day, a day when the world laid down its arms to end the greatest war it had ever felt – a war that saw the development of weapons so terrible that an international convention gathered to forbid their use. Now, nearly a quarter-century after the end of the Cold War, may we do so again. I hope that, one day, we live in a nation worthy of our veterans’ sacrifices.

Visionaries

The Space Review has a fantastic article that invaded my whole way of thinking this morning while I was trying to get into my groove for work. It casts the golden age of space exploration – the Space Race – as a contest of two visionary dreamers against their employing superpowers. It also goes a long way towards explaining the allure of SpaceX! The arguments presented therein may or may not be right, but they certainly form an interesting view to read.

It’s a fantastic and different historical perspective. Plus, some of the author’s writing includes delicious indictments of the use of space technology for evil.

Threat assessment

Sometimes, I wish I had more Republican Congressmen to write to.

Human-caused climate change is a national security issue. It threatens our lives, our property, and our way of life. And it is the only thing that we know, for a scientific fact, will threaten the American people in the future. We ought to start treating it as such, and start investing, on a national scale, in stopping it.

Ignoring the problem is, in my mind, tantamount to embracing Chamberlain’s security strategy in the late 1930s: a course for further destruction and calamity.

A difficult question for space advocates

It’s that time of year again! That is, it’s NASA Authorization Act time.

Mostly, I agree with Dr. Steve Squyres’ views. NASA does need a clear long-term goal, it is getting too little support for its missions, and it would be best to leave implementation details up to the space agency’s own program management. But that’s not what I want to discuss here.

What I want to write about is the troubling effect NASA budget and mission discussions has on space advocates. They get the Mars people at the throats of the human exploration people, as the space technologists snipe at Earth science supporters. Meanwhile, the pro-aeronautics camp trashes the education outreach groups and the outer moons proponents try to make off with the fundamental scientists’ stuff.

Everyone wants a piece of the pie, and there’s not enough to go around.

The resulting NASA policies over the past several decades years have been on the incoherent side, and I think that is because the space community shies away from a really difficult question – a question that we currently cannot answer well. The crucial thing that we have to pin down is this:

What is the driving purpose of our space program?

I don’t mean to ask whether we should or should not have a space program. Suppose the answer is “yes.” Now, we need to identify what it’s for. What do we want out of NASA?

The reason why I want to ask this question is because NASA’s short- and long-term goals should fall out as consequences of our answer. We need not bicker over whether we should build a Space Launch System or wrangle an asteroid into lunar orbit. The value of those items should be clear when we measure their contribution to the overall NASA mission.

I also don’t mean to ask whether NASA’s goal should be the Moon or Mars. Those are points on the map, and they are not ends in and of themselves. They are destinations, not purposes. Even if we get to the destinations, the space program will not thrive without a purpose. We’ve seen that before.

So let’s ask ourselves the big question. The one that space advocates don’t want to talk about, I think, because they are afraid of sounding a little crazy when they answer.

Is the answer, for example, that we want NASA’s purpose to be to find extraterrestrial life? Should the space program’s goal instead be to expand human life to colonies beyond our home planet? Or ought NASA’s biggest prerogative be defending the Earth from asteroid impacts? Do we have such a need for tangible short-term benefits that space technology development is the best answer? Should cranking out fundamental scientific research be the main goal of the space agency?

I contend that each of these answers implies that some destinations, missions, and technologies would be better choices than others. This is a good thing, because then our overall purpose for NASA will clear up the annual muddle. For example:

  • If NASA’s purpose is to find alien life, then we ought to be sending as many robotic probes as we can to get under the ice of Outer Solar System moons like Europa, Enceladus, and Titan.
  • If the goal is sustaining human colonies on other worlds, then human exploration of Mars and/or the Moon should get the lion’s share of NASA attention.
  • If planetary defense is the motivating goal, then the space program should be doing all it can to characterize, explore, and learn to manipulate asteroids and comets.
  • If space technology is the purpose, then NASA probably ought to be developing and expanding on the International Space Station.
  • For basic scientific research, the agency should be putting up all manner of space telescopes and sending probes to easy-to-reach targets, like Mars.

I don’t mean to suggest that NASA should do nothing else. But the main thrust of NASA activity really should support the overall goal directly.

Personally, I think the main purpose of the space program should be to locate extraterrestrial life (with human colonization a close second). Discovery of alien life would be a world-changing event. I think that’s the kind of impact we should be trying to achieve. Locating extraterrestrial life wouldn’t be the end of the story, either – if it is found, then other goals will quickly ensue. So, I see that as a good self-perpetuating purpose for the space program. (Human colonization of space is a close second.)

I want a big, ambitious purpose for NASA. I want that purpose to be unambiguously clear. And I want the purpose to be persistent enough to drive budget authorizations for enough political generations that we actually see progress towards the goal. In order for all that to happen, though, the space community needs to first identify the goal!

Money matters

The whole public debate about sequestration, cutting the deficit, and stimulating the economy is looking in the wrong directions. The broad solutions are simple: (1) the federal government should not spend as much as it does in relation to its income; (2) the government should target its fiscal policies in a way that makes the US economy expand. The details, of course, are where everybody bogs down.

I’m an engineer. I like to solve problems by looking at data and figuring out where to apply pressure to a system to get it to do what I want. Clearly, where I apply that pressure matters: it’s better to target the big-ticket items than the small fry. This approach means, simply, that cutting federal discretionary spending is almost completely irrelevant. Instead, proposals for managing federal spending should be looking at cutting things like the military. (This is one good thing about the sequestration plan: it forces the issue of cutting our ludicrous amount of military spending.) The politicians resistant to touching the military budget sometimes argue about the number of jobs involved – not just soldiers, but civilian contractors to the military. We wouldn’t want to hurt the economy by cutting military spending, right? Well, as it turns out, the military budget is not well-correlated with GDP growth. One reason for this result might be that, while the military is certainly interested in investments, infrastructure, advanced technologies, and new medicines – all things that can make for jobs and growth in the wider economy – the military also isn’t exactly interested in sharing those things with the civilian community through a commercialization process. It wants to invest in itself alone. This does not help make the economy grow. So, there is plenty of room for cuts in the military budget (and plenty of room to remain comfortably secure, too).

A well-crafted budget plan should also look at diverting spending towards programs that have the greatest positive impact on our economy and society. Yes, I’m talking about increasing some areas of federal spending as part of a deficit reduction solution. That’s because of multiplier effects – sometimes, the government can take actions that reverberate throughout the economy and generate positive benefits for everybody: jobs and wealth for citizens, increased tax revenue for governments. Win-win!

Increasing spending happens to be about the same in deficit and revenue terms as cutting taxes, but the multiplier effect from tax cuts isn’t going to be much to help. They provide some amount of economic growth, but there are a lot of studies that show that the effect is less pronounced than changes in government spending. Here is a good article outlining both sides of issue. In my opinion, the preponderance of evidence is that most economic growth for every dollar cut from federal taxes is lower than the economic growth from boosting spending. However, even the studies that don’t agree with me tend to show that most of these actions have multipliers up to about 1.6 – for every $1 of taxes cut or spending increases, GDP grows by $1.6. As long as this number is greater than 1, there’s a positive effect on the economy, but a 60% return on investment may take a while to have positive effects in society at large.

Fortunately, there are some slam-dunk areas where a little government investment goes a long way. One example is highway infrastructure investment: it may not be sexy, but it apparently carries a multiplier greater than two! This means the if the federal government cut $2 from the Pentagon budget, but invested $1 in the Eisenhower Interstate Highway System, then not only would the deficit shrink by $1 but the economy would grow by $2! (Plus, we would have bridges that don’t fall down.)

Even highway spending, though, isn’t as good as the government could do.

There’s this one government program that happens to provide a staggering return on investment, and is hugely popular with all demographics, but doesn’t really get a lot of federal budget love. It’s called the National Aeronautics and Space Administration. (I bet you were wondering when I would say something about space!)

For every $1 that the government spends on NASA, it spends about $200 on other things. But for every $1 the government spends on NASA, the economy grows by….well, a Freakonomics panel says that the economy grows by $8 – an 800% return on investment. A Rutgers University report posted on the Johnson Space Center web site puts the return at $7 (not just for NASA, but for research and development in general, as well). And here’s a link to a 2002 article that suggests that for $64 million of investment from the government through NASA, private companies received a “value-added benefit” of $1.5 billion, making a ratio of over 1 to 23. If a broker came to you offering an investment account with a historical 2300% rate of return, wouldn’t you take it? Purely as an engine of economic investment, without getting into any of the scientific, technological, or sociological benefits, NASA is a tremendous success!

Certainly, our national representatives should be engaged in a thoughtful and difficult discussion over what programs to reduce and which to expand. If they are smart about it, though, they should look at preserving – or even enhancing – those programs that benefit us the most. They should look at the data and target their actions.

Therefore, cut defense – I have enormous confidence that the Pentagon will successfully figure out how to prioritize. Cut some entitlements – there are certainly bloated programs out there. But fund infrastructure. Fund research and development. Fund the NSF, NOAA, NIST, DOE, and USGS. And fund NASA!
