I started Do the Math in 2011 as a way to reach a larger audience than a handful of students every year or two in an energy course at UCSD. I had (and still have) deep concerns about the assumptions we make as a society based on our fossil fuel trajectory over the last century or so. Trying to steer policy from the top seemed a losing proposition: feckless politicians hew to their constituents’ desires via a mechanism we call democracy, so why not try to get people on board directly?
I never imagined creating a blog that would get millions of pageviews, although this by itself falls well short of having an impact on a grand scale. But I figured I owed it to myself to reach as many as I might. What I have found is that a select few seem to share my concerns. And some vocal contributors to comments strongly disagree that we need to worry (why then make the seemingly wasted effort to respond to—in their eyes—doomsaying kooks if in fact we need not be concerned?). But most people simply don’t care enough to tune in. They’ve learned to ignore prognostications of any flavor, perhaps. Lately, even fewer people are entertaining ideas of resource limits owing to increased global oil production (led almost entirely by U.S. shale oil) and a recovering economy.
But I think there is something more fundamental going on here. I think we’re dealing with personality traits cooked into human nature. Are we capable of mitigating a far-off potential calamity via proactive efforts decades ahead of a putative crisis? In this post, I’ll use some survey data suggesting that we may be in trouble.
I should have done it right the first time. I now realize that I’m hungry for a tiny bit more information in relation to personality type. I have had almost 500 responses to the previous query (see previous post, below). The results are fascinating. I have added two quick questions that will give me a fair bit of insight into some key systematic issues.
Even if you have answered the poll already, I would appreciate a quick moment of your time to answer two additional questions (click here). It requires very little time: especially if you responded to the first survey request.
If you did not respond to the first survey, please do this one.
Instructions appear on the survey page for how to determine your Myers-Briggs type, if you do not already know it. Thanks for your patience, and look for a post in mid-April with the jaw-dropping results.
I have a new post written up, but thought that before I release it I should get some delicious new data.
To that end, please take this single-question bare-bones survey (link decommissioned; see this post) about your personality type. There are sixteen choices in a drop-down menu according to the Myers-Briggs personality type indicator. If you do not already know your type, you can find free online versions. While I have no particular affinity for this specific one, it may be good for the sake of uniformity that you go take this one. It’s 72 yes/no questions (should take 5–10 minutes).
Just remember to be honest and answer for the person you are, rather than the person you may aspire to be (if different).
And don’t forget in your excitement to indicate the outcome on my lighting-fast survey (link decommissioned; new survey here).
The holiday season is upon us, and for many, this translates into a marked uptick in the consumption of tasty food treats. I’m no different, and can really pack it in on such occasions. For instance, the day after Thanksgiving this year, I stepped on the scale to find myself about 5 pounds (~2 kg) above normal weight. I kicked in my diet plan, and by Monday morning (3 days later) I was back to normal. Resume course. I use a simple formula, backed by physics, that works every single time. The topic is Do-the-Math-relevant for two reasons: it applies quantitative physics to everyday life, and it touches on attitudes relevant to energy/resource conservation.
Sometimes considered a taboo subject, the issue of population runs as an undercurrent in virtually all discussions of modern challenges. Naturally, resource use, environmental pressures, climate change, food and water supply, and the health of the world’s fish and wildlife populations would all be non-issues if Earth enjoyed a human population of 100 million or less.
The subject is taboo for a few reasons. The suggestion that a smaller number would be nice begs the question of who we should eliminate, and who gets to decide such things. Also, the vast majority of people bring children into the world, and perhaps feel a personal sting when it is implied that such actions are part of the problem. I myself come from a long line of breeders, and perhaps you do too.
Recently, participating in a panel discussion in front of a room full of physics educators, I made the simple statement that “surplus energy grows babies.” This is motivated by my recognition that population growth bent upwards when widespread use of coal ushered in the Industrial Revolution and bent again when fossil fuels entered global agriculture in a big way during the Green Revolution. These are really just facets of the broader Fossil Fuel Revolution. I was challenged by a member of the audience with the glaringly obvious statement that population growth rates subside in energy-rich nations—the so-called demographic transition. How do these sentiments square against one another?
So in the spirit of looking at the numbers, let’s explore in particular various connections between population and energy. In the process I will expose the United States, rather than Africa, for instance, as the real problem when it comes to population growth.
People can be individually smart and collectively dumb. Or some may argue that people can be individually dumb yet collectively smart. When it comes to plotting a future path, I think we often get the worst of both worlds. In this post, I’ll look at the role that mental horsepower plays in our societal narratives, for better or for worse. We’ll explore two aspects to the problem: people who are so smart that they have dumb ideas; and smart people who are held captive by the manufactured “dumb” of society.
A word of warning: “smart” and “dumb” are loaded words, and even impolite. We place so much value on intelligence in our society that being called smart can make a person’s day, while being called dumb can cut to the core. We’re very sensitive to people’s perceptions of our intellectual standing, and some of the choicest insecurities are laid upon this foundation. I use “smart” and “dumb” as blunt instruments in this post, so if you’re particularly touchy on the topic, either steel yourself or skip the post and call it the smartest thing you did all day.
Let me preface what I am about to say by the disclaimer that most of this is conjecture. I have little data, relying instead on hunches about what makes people tick based on personal observations.
One other disclaimer: this isn’t a post whose veiled message is how smart I am. I might once have thought so, but then I met bona-fide geniuses when I was in grad school at Caltech. Fortunately, I was mature enough at that point for it not to cause a crisis of confidence or identity, and rather enjoyed the window I had into the off-scale brilliance of some individuals. So let’s go ahead and put me in the dumb box so we can move on to what I want to say.
I will ultimately be sharing the results, but the habitual readers of the aforementioned sites are perhaps not representative of the population at large.
Thus I would like your help in pushing this out to a broader population. See if you can get your friends and family members to take the survey, and perhaps even pass the link on to their friends, etc. I’ve never done this sort of thing before, so do not know what to expect. But let’s give it a try, yeah?
One day, sitting around with a group of undergraduate physics students, I listened as one made the bold statement: “If it can be imagined, it can be done.” The others nodded in agreement. It sounded like wisdom. It took me all of two seconds to violate this dictum as I imagined myself jumping straight up to the Moon. I may have asked if the student really thought what he said was true, but resisted the impulse to turn it into an impromptu teaching moment. Instead, I wondered how pervasive this attitude was among physics students and faculty. So I put together a survey and in this post report what I found. The overriding theme: experts say don’t count on a Star Trek future. Ever.
We humans owe much of our success to our ability to recognize patterns and extrapolate trends to anticipate a future state. My cats, on the other hand, will watch a tossed toy mouse travel toward them across the room—getting ever-bigger—all the way until it smacks them between the eyes (no, they’re not strapped down—I’m not that sort of scientist). But far beyond an ability to avoid projectiles, our ancestors were able to perceive and react to changes in local food and water supplies, herd movements, seasonal cues, etc. Yet this fine tool can be over-used, and I see a lot of what I call ruthless extrapolation. In almost every case, extrapolation works until it doesn’t. When the fundamental rules of the game change, watch out!
As with many aspects of human behavior, some of the finest commentary on the matter is served up by The Simpsons. In one episode, Lisa Simpson is taken to the orthodontist to evaluate whether or not she needs braces. The “doctor” runs a simulation based on current growth rates, producing an alarming graphic of teeth gone wild.
Marge shrieks and is ready to do whatever it takes to protect her daughter against this cruel fate. Extrapolation can, of course, be used to argue both for impending doom or future prosperity—sometimes based on the same data. I started this blog with an extrapolative foil to demonstrate the insanity of continued physical growth, in fact. A tangential follow-up illustrated the hopelessness of differentiating a steady-state energy future from an energy crash using current data (although a continued exponential rise is already a poor fit).
I’ll cheat on my bi-weekly posting plan and slip in this podcast conversation between Chris Martenson and myself, covering many of the topics I have written about in the last year.
If you don’t have 45 minutes, and are a faster reader than I am, a transcript is also available—mercifully leaving out many utterances of “um” and “you know” (which is all I seem to hear when I listen to a recording of myself). The original source and surrounding intro/write-up can be found on the Chris Martenson website.
