I realized as I was reading this that I know very little about sociology as a discipline. In particular, I'm unaware of any of its "Great Theories", a la General Relativity for physics, or Darwinian Evolution for biology. Any candidates? I'm not trying to be snide, I really would like to learn more about this. The Wikipedia page for sociology describes "theories" that sound more like schools of thought.

I would posit the social signalling theories of Robin Hanson as perhaps a theory of this magnitude.

The problem is, though most of Hanson's theories have plausible explanations and "feel" right, there is very little experimental evidence and very few studies are directed in that area. In fact, you might even say it is a symptom of that type of signalling itself: as homo-hypocritus, we don't want signalling theories to be proven true so we make up reasons for deriding signalling explanations as not rigorous enough to even merit being properly tested or studied. Of course, this too is no better, because then do we just actually have no evidence to believe in signalling explanations, or are we using signalling excuses to suppress the meaning of that evidence? It's somewhat self-defeating.

The next most important theory I would posit is Prospect Theory by Kahneman and Tversky. But there again, many aspects of it have not been successfully replicated, and too often limited experiments are generalized too much.

One set of social theories that I would love to see given more quantitative foundations is the research from the book Moral Mazes. Robert Jackall carried out some lengthy longitudinal studies in which he collected anecdotal narrative and interview data from employees at all seniority levels through a couple different firms. He was able to see people rise up the corporate ladder, people get fired, executives fired and replaced, large layoffs, etc., and conduct informal interviews with employees all up and down the ladder.

Based on his interviews, he put together a series of theories about how morality and ethical identity form within bureaucracy, and particularly how managers develop an understanding of ethical obligations to subordinates, and how certain factions of an organization (notably HR) come to function when there are competing concerns between ethical expectations and bureaucratic mandates.

In every job I've had, it's been a frustrating experience of basically saying, "Yep, I know this chapter from Moral Mazes ..." because companies operate almost as if they've read the book as a field guide.

Yet at the same time, it's still just a qualitative study that is scaffolded by academic sociology. If it were actually possible to collect that kind of data from corporations, I'd love to see some theories from the book explored more quantitatively.

This article is a truly fantastic critique of how modern social sciences (besides economics) are carried out and publicized in modern society. Any critique one dislikes - typically "your theory predicts X which is false" - can be dismissed by "nuance", "things are more complicated", "that's different in unspecified way", etc. In statistical terms, these dismissals are little more than a call for overfitting - if I ca…

Why do you exclude economics? I see economics as practically leading the way with regard to dismissals like you suggest. One example I have first-hand experience with is the low-volatility anomaly. CAPM-like theories predict a roughly linear, positive-sloping relationship between risk and return. Yet decades worth of various empirical measurements of the riskiness of assets and portfolios unequivocally demonstrates t…

>t would be reasonable to say that CAPM is a mathematical result, and the evidence suggests the mathematical model required for CAPM simply fails to correspond to reality. But many finance folks, especially in academia, won't admit it.

In other words, "Things are more complicated in real markets". I don't see any problem with wanting descriptive theories. Economists are interested in building models whose parameters can be tweaked in ways that correspond in a clear meaningful way to a possible actions (e.g. change government expenditure on X by Y). If you try to just maximize predictive power you're missing the point. Economics can be used to predict the future, but I would say the main goal of the field is to produce theory that will provide valid methods of altering the future.

At first "overfitting" was the concept that leaped to mind as I read it, but overfitting is sort of something different. You have a complicated data set, and when you overfit, you keep adding dimensions of freedom, and then setting those dimensions of freedom to produce the original values that were passed in, such that it fails to correctly predict any other instance drawn from some conceptual "same distribution".

In this case, the theories do the "adding many dimensions of freedom" part, but they don't really fix the values; they probably haven't got data to fix in the first place, and it's not mathematical enough to be that precise about the fitting.

I think it's more like these theories are often not so much hypotheses themselves, but the descriptions of hypotheses spaces, and the addition of "nuance" means that in a lot of cases, what sounds like a "theory" is really just the description of a space that happens to contain all or most of the possibility space in question. As much fun as it may be to do that, and as much as it may even be a necessary first step to a real theory, in practice that is not generally the difficult part of the process. (There are exceptions to that which may leap to mind but I submit they would be the exceptions, rather than the rule.) When one is working with fuzzy words (even if by necessity!) and not math, the fuzzy words make it very easy to make this mistake, I think. English does not have a strong distinction between a hypothesis space and a specific hypothesis in that space, as evidenced by the very fact I have to dip into jargon to even make that point!

From that perspective, the solution that leaps to my mind is implement the observation that in many ways, the important thing about a theory is not what it describes, but what it excludes. It is too easy and cognitively tempting to try to create a theory that, when you fiddle with the parameters, describes everything you see, but the real questions are, what is excluded by your theory? Can I fiddle with the knobs in your theory to describe something that you say ought to exist, but does not seem to? Is your theory even well-enough specified that these are meaningful questions to ask about it?

I don't know the answers to these questions for sociology. I have to admit I've tried to engage with it a couple of times, because what fan of Isaac Asimov doesn't want to learn about some real-life psychohistory, but I've always found it difficult to get traction with with my engineer mind. I can engage from a philosophical point of view, but that is not generally what I was looking for; I've got, well, philosophy itself for that. (Repeat previous sentence for history, psychology, and economics.)

To p4wnc6's question, I'd submit that as dismal as the Dismal Science may sometimes be, it does often meet this bar. I fear economists themselves may often be quite sluggish at recognizing when their own theories are contradicted by the evidence because the theories are saying that what is currently happening (in the general sense, not the literal March 27, 2016 sense) is excluded by the theory, but that is a human problem, not an economic theory problem. Economic theories do exclude things; if supply rises and demand holds steady, the vast majority of possibilities where price goes up are excluded, and if price were to go up, the theories would be useful in investigating how such a thing actually happened by examining what such theories would still permit (e.g., perhaps supply isn't really rising because the new supply is actually a higher quantity of lower quality, and too much of the demand is for a higher quality than the new supply is supplying which means "real" supply is dropping, or something like that). They certainly aren't perfect and a given theory may even be wrong, but, well, the very fact that a theory can be wrong is evidence that it is falsifiable, and thus not "nuanced" into infinite psudo-explanatory power.

> In statistical terms, these dismissals are little more than a call for overfitting - if I can arbitrarily add more dimensions to a theory, I can make it fit any data set.

Sure. However, this leads me to believe it is statistics that are the problem, and not nuance. You are in my opinion admitting that nuance invalidates most statistics, or at least allows for heavy manipulation of the statistics to fit any narrative. This is precisely why public policy should not be made using statistics. Society should not be likened to a turing machine. People, history and so many topics of discussion are full of nuance, detail and perspective; and disregarding nuance (or perspectives) is insulting to the truth.

This doesn't make a lot of sense in this example with CAPM. The economic theory provides something that is abjectly wrong. It is literally claiming there is a positive relationship between two quantities when the evidence suggests the relationship is negative.

The theory is grossly qualitatively wrong, not merely just on the edge of being quantitatively wrong in a few cases or something.

I assume simple theories are very good for advancing the science itself. But I don't think they are as actionable as complex ones, because reality is complex, and you need to account for that when creating policy.

Can we un-capitalize "Nuance"? For a second I thought it refers to the speech technologies company.

Same. I actually clicked hoping to read a rant against my least favorite speech company and their bad habit of buying up competition for the patents and then sitting on the technology. They own the rights to the speech synthesizer I use every day, Eloquence, which is no longer developed and will probably never improve, but is easily the most intelligible synthesizer at high speed.

By calling for a theory to be more comprehensive, or for an explanation to include additional dimensions, or a concept to become more flexible and multifaceted, we paradoxically end up with less clarity. A further odd consequence is that the apparent scope of theories increases even as the range of their explanatory application narrows. This seems analogous to poor imperative programming to me: as your code becomes m…

I think this is better understood as a consequence of Bonini's paradox ( https://en.wikipedia.org/wiki/Bonini%27s_paradox ).

I thought of the map-territory jawn, as well.

What you are describing in economics - while perhaps a failure mode - is the exact opposite of what this article discusses. The critique of this article is that valid abstractions and theories are rejected due to a lack of "nuance", rather than a failure to explain and predict reality:

Second is the ever more extensive expansion of some theoretical system in a way that effšectively closes it oš from rebuttal or disconrmation by anything in the world...It is an evasion of the demand that a theory be refutable.

Your critique of some economic theories is a totally different one - that they make specific predictions which don't come true.
