It is a followup to my earlier article The Arithmetic of the Ph.D. Glut. To recap, sure there’s a Ph.D. glut in almost all STEM (Science, Know-how, Engineering, and Arithmetic) fields in america. As a matter of federal authorities coverage, many extra Ph.D.’s are produced than could be employed as professors or other forms {of professional} researchers. The Ph.D. glut in biology and medication is very dangerous presently as mentioned in Brian Vastag’s July 7, 2012 Washington Put up article U.S. pushes for extra scientists, however the jobs aren’t there. There was a Ph.D. glut in most STEM fields together with particular fields equivalent to arithmetic and physics the place particular shortages are sometimes both claimed or strongly implied since about 1970.
The insurance policies which have resulted in a perpetual Ph.D. glut since about 1970 are regularly justified by express or implicit claims that extra Ph.D.’s (or other forms of STEM staff) will translate into extra scientific and technological progress and extra “development,” a well-liked political mantra. Has the Ph.D. glut in biology and medication cured most cancers? Not to this point — after forty years and about $200 billion in inflation adjusted {dollars}. Many different particular examples of lack of scientific and technological progress could also be cited. In truth, the Ph.D. glut is related to a decline in actual development charges and a slowing of scientific and technological progress in most fields aside from some areas of computer systems and electronics.
Disappointing Outcomes
What does the proof present? Remarkably, each the expansion charge of the US Actual Gross Home Product (GDP) and the expansion charge of the per capita US Actual Gross Home Product had been considerably increased previous to 1970 than since. Now, the decline within the US development charge is a worrisome long run pattern. It’s troublesome to tie to anyone occasion or coverage. It has occurred underneath each Republican and Democratic Presidents and Congresses. The decline has occurred regardless of and maybe due to the adoption of a number of insurance policies such because the overproduction of Ph.D.’s and monetary deregulation which might be routinely and uncritically justified as producing elevated “development.”
I take a look at total financial development for an essential cause. Analysis and growth is dangerous and unpredictable. For any given analysis area, one can argue that the issue, e.g. most cancers, has proved rather more troublesome than anticipated. That could be true. Luck unquestionably performs an enormous function. That is economist Paul Krugman’s rationalization for the overall lack of progress during the last forty years: the place is my flying automotive?
However is all of it simply dangerous luck? By wanting on the complete financial development charge we will, at the least partially, common out the idiosyncracies of various fields. The Ph.D. glut is a common downside in almost all analysis fields not simply excessive profile fields like physics, arithmetic, and molecular biology.
The plots beneath present america Actual GDP and Actual GDP per capita since 1947. The GNU Octave script and the uncooked information used to make the plots is supplied within the appendices. The uncooked information is from the St. Louis Federal Reserve/Bureau of Financial Evaluation (BEA) and the U.S. Census Bureau.

The evaluation exhibits:
MEDIAN REAL GDP GROWTH RATE 1947-1970 ans = 0.040710 MEDIAN REAL GDP GROWTH RATE 1971-2011 ans = 0.027481 MEDIAN US REAL GDP PER CAPITA GROWTH 1947-1970 ans = 0.026985 MEDIAN US REAL GDP PER CAPITA GROWTH 1971-2011 ans = 0.017927
The median actual GDP development charge from 1947 to 1970 was 4.1 p.c (rounded to 2 vital digits), versus 2.7 p.c from 1971 to 2011. The median actual GDP per capita development charge from 1947 to 1970 was 2.7 p.c, versus 1.8 p.c from 1971 to 2011. The median is used to keep away from the consequences of outliers which may make the common or imply deceptive. There may be, for instance, a possible outlier within the GDP information in about 1950, a development charge of about 12 p.c.
The info exhibits an accelerating downturn in development charges during the last 20 years. This coincides with the current rise in lots of actual power costs equivalent to gasoline. After all, correlation doesn’t show causation. Plenty of issues have risen sharply within the final 20 years together with the Web, common laptop use, cell telephones, consumption of aspartame (the sweetener in Food regimen Coke), consumption of excessive fructose corn syrup, and diagnoses of autism (see the earlier article The Arithmetic of Autism), for instance.
It’s possible that the one greatest proximate reason behind the disappointing development during the last forty years has been restricted and disappointing progress in energy and propulsion expertise. The plot beneath is from america Vitality Data Administration and exhibits the true, inflation-adjusted value of a gallon of gasoline during the last forty or so years. These costs present a common reversal of the earlier pattern of declining actual costs of gasoline in the course of the early twentieth century (1900-1970).
The rising actual value of gasoline presumably displays that the manufacturing of gasoline and different competing power sources has not saved up with rising world demand. Take into account that most demand comes from the so-called developed world: america, Europe, Japan, and some different nations. It might require one thing like a four-fold improve in world power manufacturing to boost the usual of residing of your complete human race to US or European ranges.

Why Have Extra Ph.D.’s Produced Much less Progress and Development?
The coverage of overproduction of Ph.D.’s is predicated on quite a few assumptions which might be not often said or mentioned. Remarkably, it’s fairly attainable that coverage makers, enterprise leaders, and others have by no means thought by what they’re doing and why. It’s uncertain that getting old coverage makers, senior scientists and others would consciously sabotage makes an attempt to seek out cures or efficient therapies for most cancers or different illnesses of outdated age, though that’s what they could nicely have executed with the present glut of biology and medication Ph.D.s. Equally, only a few coverage makers, senior scientists, or others, besides maybe just a few power trade moguls, profit from the dearth of progress in energy and propulsion expertise, particularly if we run out of oil, pure fuel, and different hydrocarbon fuels with out discovering a alternative: the Peak Oil situation.
Generally, science — and with it arithmetic — public coverage is predicated on a crude bodily analogy. Scientists, at the least the graduate college students and post-doctoral researchers, are envisioned as primarily mental ditch diggers. Intelligence is envisioned as a single linear scale somewhat like Pearson’s common intelligence and equated to the bodily energy of the ditch diggers: a easy “psychological horspower.” If you would like extra, higher outcomes, rent extra and stronger mental ditch diggers. Maybe, there are just a few tremendous ditch diggers who’re ten instances stronger than the common ditch digger. It might be good to rent them however you’ll somewhat not pay them ten instances as a lot.
Considerably associated is a perception that management over the mental ditch diggers is an effective factor. The extra management, the extra doubtless you’ll get higher outcomes. Thus, slave labor from India and China is predicted to supply higher science and expertise than free labor from america. This latter view appears particularly suspect. Even in bodily labor, had been the free manufacturing unit and farm staff of the North who may give up their jobs in disgust if mistreated actually much less productive than the slave labor of the antebellum South? Not solely did the North forge forward into the commercial period leaving the South far behind, however England and France grew to become depending on imports of meals from the North, not the South, so when the Civil Battle got here, England and France in the end sided with the North regardless of “King Cotton” and the textile trade lobbies.
The Ph.D. glut mixed with the heavy importation of visitor staff from India, China, and different Third World nations who usually face severe financial hardship if fired and despatched house — a typical destiny — creates a scenario approaching slave labor. Can slave labor actually treatment most cancers or invent new sensible power sources? Don’t maintain your breath!
The logical implication of this implicit mannequin of scientific analysis is easy: throw some huge cash and manpower underneath centralized bureaucratic management at an issue like most cancers and it’ll fall. There have been many makes an attempt to do that since World Battle II, impressed partially by the spectacular success of the Manhattan Challenge (see the earlier article The Manhattan Challenge Thought-about as a Fluke). Just like the Battle on Most cancers, most of those efforts have
Nonetheless, if scientific and mathematical analysis and growth just isn’t analogous to this idea of digging ditches, one may count on the Ph.D. glut to trigger severe issues. The Ph.D. glut depresses wages and dealing circumstances in essential analysis areas equivalent to well being and power. The purported “greatest and brightest” in america go elsewhere — growing pseudo-scientific mathematical fashions for Wall Avenue with disastrous penalties or, considerably higher, growing apps to promote pet meals over iPhones and comparable gimmicks with restricted however at the least constructive advantages. Elevated amount can’t make up for the lack of high quality.
Most significantly, the Ph.D. glut vastly reduces the independence and inventive freedom that has so usually confirmed obligatory to resolve extraordinarily laborious scientific issues like most cancers or new power sources. The Ph.D. glut signifies that egos and politics dominate. Unique thinkers can simply be eradicated and compliant sure males rewarded with the few everlasting positions. Close to slave labor from Third World nations will solely additional cut back this independence and inventive freedom.
Conclusion
As the information exhibits, the Ph.D. glut is related to a long run decline in development charges in america. Whereas quantitative information are restricted, it’s related to a qualitative decline within the charge of scientific and technological proress in lots of fields, particularly energy and propulsion applied sciences. There may be the notable exception of some laptop and eletronic applied sciences, though synthetic intelligence (AI) really exhibits an identical disappointing charge of progress — not like CPU clock speeds or video compression algorithms the place progress clearly has been spectacular and akin to the historic pre-1970 ranges in lots of different technical fields.
