What Does IQ Measure and Why Does This Matter?

Standard

There are many alt-right types who use IQ statistics to distinguish between groups of people, and yet they themselves do not seem to grasp statistics or even understand what IQ actually measures. They suggest their own lack of intelligence through this. And, given that their use of IQ is most often directed at those whom they deem to be inferior races and is what makes them feel superior, this is deliciously ironic.

Yes, certainly IQ does matter. But it matters in the same way that hitting a golf ball and bench pressing do as being a measure of overall athleticism. Sure, it does differentiate natural ability for those with equal training, and yet says very little about the inborn abilities of those coming from vastly different circumstances. In other words, I can out bench many bigger men who never saw a gym. But not because they couldn’t outperform me if they put the same time in. And, likewise, the kind of intelligence that IQ tests measure is built on practice.

So, basically, without a multi-variant analysis, the results of IQ tests tell us very little. A person can score high because they are genetically gifted. They could score high because they had a stable home, good nutrition, and high-quality education. And, like Koreans getting taller on average, lower average IQ today does not mean the same will be true tomorrow or if all circumstances were equal. In fact, IQ tests are increasing generation by generation, this is called the “Flynn Effect” and not necessarily a result of people actually getting smarter than their grandparents.

No, IQ tests tend to focus on a kind of abstract reasoning that has no practical application for prior generations or those who are raised outside of an advanced economic system. My ability to reason through engineering problems may unlock earning potential in a very controlled environment and yet doesn’t mean I would survive a day in the Amazon basin or on the streets of Rio. So this assumption that my test scores prove something about my superiority is basically nonsense.

Sure, not everyone has the mental capacity to solve differential equations. But that doesn’t mean everyone who couldn’t solve them prior to Isaac Newton and Gottfried Leibniz was an idiot.

The really crazy thing about racial supremacist mid-wits (or at least those who I know of European ancestry) is that they will so often make fun of the pointy-headed intellectuals (those who outscore them in IQ while lacking street smarts) only to turn around and use IQ statistics to create a racial pecking order. I mean, if IQ is a reason for some to rule, why do these same people turn to wild conspiracy theories to explain why many Ashkenazi Jews are disproportionately more successful (academically) and in positions of power or influence? Why not just assume they are the next stage of human evolution?

The truth is culture and environment have a large part to play in our development. What is prioritized in homes and communities can make a huge difference in outcomes. If my dad was an attorney and I was sent to a prep school, I would probably be more likely to score higher and go further in pursuit of a professional career. Alternatively, if I was raised in a place where everyone was obsessed with track speed and achieving celebrity status, I doubt I would’ve grown up playing with Legos or visiting various museums with my parents. My own 97th percentile IQ was likely built on experience as much as anything else.

Lastly, it is worth noting that outliers do not tell us a whole lot. Interestingly enough, men are both smarter and dumber than women and this has to do with standard distribution or how the bell curve works. What this means is that there can be more or less diversity within categories. Or, put otherwise, some Kenyans being excellent long-distance runners doesn’t mean all are and this superiority of some Kenyans will tell us even less about those on the other end of the African continent. Too often we look at the cream of the crop (or bad actors) as an indication of the whole and yet group statistics never tell us about individuals.

Tesla’s Uphill Battle in the Trucking Industry…

Standard

There is no question that Elon Musk has changed the conversation as far as electric vehicles.  Musk, unlike his predecessors, focused on building an image of luxury and performance.

Electric powered vehicles, until the Tesla Model S arrived as an option, were boring, slow and impractical.  Now, while Musk’s cars still remain impractical for most people (both in terms of range and price) and while it remains to be seen whether or not his company could survive without corporate welfare, Tesla has at least undone some of the negative image of electric vehicles.

Tesla seems to be taking one more step in the direction of practicality with the introduction of commercial vehicle.  Semi, this latest opportunity for Musk to attract media attention, reminds me of something I would’ve drawn up in a middle school daydream: It has a sleek exterior, it is loaded up with LCD screens, it promises to perform at a level one would expect from a sports car, it is priced similar to other Class 8 trucks, and yet also makes me question if any experienced truck drivers were consulted in the design process…

Sure, middle school me would be salivating over this technological wonder.  However now, as one having had years of experience behind the wheel of a big rig, the center seating position, glare of screens, wheel fenders and charging times make it totally unappealing to me.

The ergonomic and design issues, obvious from a driver’s perspective, are covered in another former trucker’s article (click here if you want to know more about them) but there are more serious matters and practical concerns yet to be addressed.  Acceleration numbers and having the fastest truck on the road might increase coolness factor, but it might also leave all of your cargo on the road (or like the unmitigated disaster recalled unfondly from my days unloading trucks at the paint store) and distracts from questions of actual viability in the real world.

To many the promised 300-500 mile range and 30 minute recharging may seem wonderful. But, from a trucking industry standard, it is truly abysmal and completely impractical.  The range of an over-the-road diesel truck, with 250 gallons of fuel, is anywhere from 1000 to 2000 miles and it only takes fifteen minutes every other day to refill the tanks—multiple extra stops per day is intolerable given the current hours of service requirements.  

And, that’s assuming good conditions, what happens in cold weather when battery capacity is reduced by 40-50% like owners of other Telsa products have experienced?

It is no big secret that fossil fuels carry a greater amount of energy per pound than the alternatives currently available. This energy density is especially important in commercial trucking where every ounce of extra weight takes away from payload.  Batteries with the range Telsa has promised will certainly be very heavy and that will be a huge competive disadvantage.  It means you might need an additional Tesla truck to do what one diesel truck does—which wipes out any illusion of energy savings and cost effectiveness.

Then there is the question of longevity and servicing the truck.  It could very well be that the Tesla Semi will be completely reliable and go a million miles like a diesel truck.  But, even assuming that is the case, what sort of maintenance program and roadside assistance will they offer when things do inevitably go wrong?  Service infrastructure is a more significant in commercial trucking than it is in general.  Diesels are relatively easy to work on and the network is already established—those are questions that must be answered.

My own back-of-the-napkin analysis, based in what has already been said and can be reasonably assumed, is that this new Tesla offering will have the same liabilities of other battery electric vehicles except on a far larger scale.  The question of Tesla being the future of trucking (or is simply a niché vehicle for those who can afford the unavoidable range and weight disadvantages, as well as potential maintenance issues) is not answered.

Trucking companies, unlike wealthy luxury car buyers aided by government subsidies, need to be profitable and competive to survive.
