The answer would be rigor. A huge problem with sociology is the dependence on the story. Unfortunately, since the sociologist is often a human with their own biases, they are going to see what they want to see.
For example, I purchased the Kindle version of the book the author recommends ("Coming Up Short"). I turned to the appendix, where the author describes her research methodology. And sure enough, the research involves open-ended questions ("Walk me through a typical day at work." "Is there a time you lost a job? Could you describe it?") that could lead the interviewee to respond in any way they want.
There are many problems with this, such as : 1) the interviewee may inadvertently invent convenient narratives that provide comfort but aren't accurate, 2) the interviewer may mis-interpret the answers, etc.
How are we supposed to develop policy off of this? Sure, it's a great starting point for starting research, but the narrative- or story-based approach should never be the conclusion.
This is why economics is so much more trusted. Although economics has flaws, and the study of econometrics can sometimes lead to incorrect conclusions, it at least uses objective data and metrics, which are less susceptible to error, providing a much more grounded approach to policy decisions.
While there are some attempts with evidence-based policy, these sciences just aren't really at the point where math is useful (yet).
Math mostly requires reducibility: the ability to split it into small parts and look at these individually. That approach worked incredibly well in physics, and with the Manhattan project at the latest, it proved that it was mightier than any human endeavour before it.
But while, theoretically, everything could be reduced to physics, that isn't always the level of abstraction that works best. If you're depressed, a physicist isn't going to help you. Medicine may – but a psychologist, even though the discipline is scientifically flawed - is still an important tool in the set available to us.
Sociology is psychology on a population-scale. In that regard, it may be almost impossible to reduce because of nonlinear effects, chaos etc. That severely limits applying results from prior experiment X,Y,Z to situation B – because what you usually do is split situation B into components (B1=X,B2=Y,B3=Z,...), each of which is quite generic and has been studied in detail. So you'd have to run your own experiment on B, and the questions of sociology would require you to run an A/B experiment, with both A and B being, for example, New York.
Is there a thing as free will, and if so, is it explainable in terms of physics? And with consciousness (if you believe there is such a thing)? Is morality and ethics reducible to physics as well? There's a lot of presuppositions to the statement that everything is reducible to some purely mechanical process.
I have no doubt that many serious people believe as you have stated, but it's not a self evidently true claim.
If so, that makes sociology completely useless for policy. A field which cannot predict what will happen next time can't actually inform a policy maker as to whether their policy is useful.
Math mostly requires reducibility: the ability to split it into small parts and look at these individually.
This is simply false. If this is your criticism of math in economics, it applies equally well to math in geophysics, oceanography, climate science, etc.
I'm surprised that you're speaking with such certainty without mentioning the rather powerful relationship between economics and finance in a classical "follow the money" trail of thought.
We are here back at the fundamental mathification problem. Economists have understood that as long as their formulas look scientific enough, they can influence with their results policy makers et al.. Sociology rarely present their research in terms of the broad and universal truth as the economists do. So while Economists' results look rigorous on paper, reality still proves it often wrong.
This is analogous to complaining that climate researchers aren't rigorous because some subset of politicians claim it isn't manmade and point to some articles which support their claims.
What specifically are you claiming?
A lot of sociology is unfalsifiable. However, this is a field in which many people still look up to Marx--a sociologist whose predictions were falsified in a rather spectacular way.
Foundational microeconomic theories, however, are easily verified in many everyday cases and frequently used to make money in practice. Furthermore note that we're pretty sure about when the foundations apply and when they don't. Being able to say "I know when this is true" is a very powerful thing. The non-economic side of sociology can't say anything like that.
Economics is a social science.
Economists, like Sociologists, have trouble predicting the future and the past.
The only thing, in my opinion, that separates Economics from Sociology is that for economic activity to take place there's also a hard substance that can be tracked, eg. money, but also other goods or services. Sociology is the social science that focuses on everything else in the field that isn't that. Sociology is Economics poor cousin, as it were.
The problem with pointing to qualitative techniques as more rigorous and less biassed, is that the bias - when it comes to data about people- often lies in the decision what to measure - especially when categorising - and how to interpret the numerical result when you have (rigorously) processed it. That is as susceptible to preconceptions of the researcher. It's just easier for an economist to hide behind the rigour applied to the quantitative part.
Compare, for example, at Colombia University, the Department of Sociology homepage http://sociology.columbia.edu/ and the Department of Economoics http://econ.columbia.edu/. The sociology page features a huge image of a protest of the recent immigration executive orders. The economics page, on the other hand, features upcoming talks like "Iceland's Road to Recovery" and "Modern Financial Markets: The Role of High-Frequency Trading". The sociology department is signaling that they're passionate about ideological issues, while the economics department is signaling that they're focused on understanding and analyzing.
People trust scientists because people believe they are willing and able to divorce their emotions and vested interests from an objective pursuit of the truth. Sociology seems to fail that test time after time.
How can you conjure up this example, and conclude that only sociology is ideological?
That would be the understatement of the century. Economics theory decide how to organize society resources, so, it's a very loaded subject with a lot of interests trying to decide what is "reality". Economics use complicated maths to justify ideologically determined policy.
I propose you a simple exercise. Go to any mainstream economic textbook and read about the fractional reserve system creation of money, that it's supposedly how the system works.
Then go and read what the people that are really in charge say about how money is created (pdf from the Bank of England):
http://www.bankofengland.co.uk/publications/Documents/quarte...
If the textbooks in economics are wrong about a basic thing like that, maybe we should start to think carefully about the subject.
Indeed. If it weren't for nutritionists, economists would win the prize for having the discipline most disconnected from reality.
I'd look at economic definitions of cost, value, and price, of ignoring the reality of thermodynamics, and of much of the theology (Thorstein Veblen uses the term "mythology") surrounding supposedly rationally-acting "homo economicus", market failures, and the role of information, amongst many others.
Money is first and principally a mechanism for exchange, and gumming up that role leads to problems. Fractional-reserve and central banking greatly assists in this, and is by and large hugely useful.
This is the exact problem, yet it is hard to get someone in the social sciences to admit it in my experience. For instance, I am a computer science student, and I'm currently taking a political science class as part of my university requirements. A recent exam question was worded in multiple choice format, to the effect that the professor was seeking an exact specific answer to a completely subjective question, such as "What is the most important issue facing China as it's population continues to grow?". It's completely absurd, and you end up with an exam full of questions with one "correct" answer, and a bunch of nonsensical gibberish for the other options.
This lack of imprecision drives me absolutely mad. I understand that social sciences are inherently dealing with subject matter that is harder to quantify than, say, computer science. But the issue is when one asserts that scientific conclusions can be made about these subjects when no formal system of reasoning exists. To quote from a recent article I read,
"Until we have a deep understanding of the brain, we can't shape falsifiable, general theories about it, and mind studies cannot provide a reliable understanding of the brain. In short, no theory, no falsifiability, no science."
http://arachnoid.com/psychology_and_alchemy/
In short, if social scientists simply accepted that their fields do not fit the traditional rigors of science, it would do much to alleviate the issue. Studying these things can still provide valuable, actionable insight. But to treat it on par with the natural sciences is fraudulent.
... because economics is a natural science?
This is exactly it. They can't prove what they know, or make good predictions. When you insert yourself into the story, you can't shake confirmation bias.
Economics is still shaky science, but the economists at least try to get on stronger fundamental footing.
Nonsense. Back to the original question, the reason why economics has influence is because it involves money. The people who hold the purse strings talk in that language, and those people always pay themselves first.
Sociology could have perfect rigor, beyond that of any other disciple, but it would never have the influence of economics.
Become obsequious towards those in power? Find out rationalizations for our current state of affairs? Come up with reasons why we live in the best of all possible worlds?
Joan Robinson once put it pretty concisely, "The purpose of studying economics is not to acquire a set of ready-made answers to economic questions, but to learn how to avoid being deceived by economists."
Quantitative work are best at telling us what answers people gave or a numerical summary of what people did. It can't tell us why people gave that answer or why they did what they did.
For instance, this article ( https://www.google.com/amp/s/www.theatlantic.com/amp/article... ).
This joke probably sums up what many people think of economists: Q: Why did God create economists?
A: In order to make weather forecasters look good.
There are numerous economics papers studying exactly what is the shape of the Laffer curve both from historical analysis as well as trying to find natural experiments. (IIRC tax revenue peaks at 50-65% tax rates, at least in the short run.) None of the politicians actually know or care about the results of these studies - as long as the sound bite is convenient as a rhetoric device to support their ideology (cutting taxes or raising taxes or whatever, it gets trotted out by politicians.
Sadly, ex-economists who definitely do know better are instrumental in this as well. People like Krugman, Mankiw or indeed Laffer got a large audience based on genuine rigorous contributions from 10 or 20 years ago - and then promptly ignore all that rigor, uncertainty and intellectual honesty when they get the offer of a $10million/year payday and a chance to mold the world according to their ideology from politicians and media.
It is the same thing with international trade, it is the same thing with state-vs-private ownership and natural monopolies, it is the same thing with costs/benefits of demographic change and migration.
It reminds me of the often-cited Stanford Prison Experiment. The lack of any rigor during the experiment is usually ignored when the findings are discussed.
The "experiment" had no control group, or even a separation between the observers and the ones involved in the experiment (Zimbardo was both the prison chief and the lead researcher). From an experimental setup point of view, it was just an amateurish mess.
The uselessness is then demonstrated by proclamations that the doubling of the unemployment rate in the recent financial crisis is caused by 10s of millions of workers suddenly developing a preference for leisure over work.
A. Has never read an economics research paper
B. Only know economics as monetary policy (or macro more broadly), and as a libertarian is inherently skeptical.
Currently, most of the interesting research being done in econ is outside of theoretical macro, so the knee jerk libertarian "economics is broken" meme doesn't hold much water as the topics and methods are pretty dissimilar. A developmental microeconomics field study in rural India is a different beast entirely from a macro theory paper. For a sample of the diversity of economics research, see here: http://www.nber.org/papersbyprog/
Returning to your comment, the issue of storytelling, in a nutshell, was what drove me crazy when working closely with qualitative sociologists. Trying to discuss falsifiability in their study design was maddening. Sociology doesn't need to adopt the same research model as applied economics but they do need a serious look at their research methods, and I have more respect for those who try to take a quantitative approach. Many of the sociologists I worked with would turn up their noses at the phrase "computational social science" and were loathe to discuss issues like biased sampling, but the best ones (IMO) used qualitative observations to drive later large-scale quantitative study, which I think should be the de-facto standard for social science research.
Their reliance on ethnographic studies can be useful for verifying the existence of some phenomenon you have a hunch exists in some form, but such research is woefully biased and wholly inadequate as a means of measuring the prevalence or magnitude of a phenomenon, which is why economics studies (or quantitative methods more broadly) tend to have more credence when presenting evidence on the same subjects.
I'm not sure why that save economics from the discussion, when it's the theoretical macro what have a huge influence in the life of billions of persons and the title of the article we are discussing is "If Sociologists Had as Much Influence as Economists".
The libertarian comment is uncalled for, as most of the comments here don't express a political view, only criticism of the discipline.
It needs to generate 'useful' political recommendations (useful to the 'right' people).
"The answer would be rigor."
No it absolutely would not. The economics profession has been actively resisting rigor. For instance, Neoclassical (still the default in policy circles) still considers private debt to have no significant macroeconomic effect and presumes, religiously, that markets trend towards equilibrium (particularly in employment).
"This is why economics is so much more trusted."
It shouldn't be.
"it at least uses objective data"
Would you have any faith in a model rooted in Newtonian mechanics that assumed away friction just because "it at least uses objective data"?
And a large body of sociological research touches on the idea of stigmatization, including of the poor and of racial minorities.
Many school reforms ideas (desegregation, elimination of corporal punishment, reducing emphasis on rote learning, etc) were based on this theory. The Brown versus Board of Education decision cited sociological research along these lines, for example. But the theories were wrong, so the solutions did not work. Professor Raymond Wolters has two exhaustive (if depressing) histories of these reforms and their failures. See The Long Crusade: Profiles in Education Reform, 1967-2014 and The Burden of Brown: Thirty Years of School Desegregation
It’s one thing, for example, to outlaw housing discrimination based on race. But if real estate agents and would-be home sellers subtly shun minority buyers, the effect can be the same. Professor Gans of Columbia has argued for decades that the stigmatization of poor Americans fuels entrenched, persistent poverty.
Sociologists haven't been ignored -- this was the theory behind Section 8 Vouchers which is a very large program. But again, the theory was wrong and the solutions did not work. See https://www.theatlantic.com/magazine/archive/2008/07/america... and http://devinhelton.com/historical-amnesia.html
I don't know if there's any research demonstrating Section 8 is superior to letting people live in abject poverty, but I think it's reasonable to have strong priors about this hypothesis.
The claim from mid-century academic sociology was that public housing (and later vouchers) in and of themselves would reduce crime and other social ills. You didn't need punitive work houses -- if you just gave the poor better housing they would start behaving better. I see no evidence that this was the case. And with regards to public housing especially, it seems to have contributed to worsening crime and social ills.
I don't find this too surprising, actually. It would be pretty strange if white people emitted pheremones (or whatever) that improve the educational performance of people around them.
...and to argue this along racial lines is simply preposterous. The idea that allowing businesses to discriminate poor minorities would actually help them is the worst kind of revisionism. The world has come a long way since the 60ies.
This was the line taught in my freshman sociology class, but I have since been convinced that money spent on social welfare does not explain international differences in various social ills.
The idea that allowing businesses to discriminate poor minorities would actually help them is the worst kind of revisionism.
That is not what I argued.
Examples please. It's not true of Sweden or the rest of the Nordic countries and if anywhere has a more extensive system of social welfare I'm unfamiliar with it.

The 2007-8 financial crisis is the most significant economic event of the preceeding 78 years. And it was virtually completely unanticipated by mainstream economists. Alan Greenspan, head of the world's most significant central bank, has conceeded his worldview was deeply flawed.
https://mobile.nytimes.com/2008/10/24/business/economy/24pan...
The Queen of England has asked why no one saw the credit crunch happening.
http://www.telegraph.co.uk/news/uknews/theroyalfamily/338635...
So: not only are you incorrect in your example of false predictions, but you're severely discounting the scope of economics' failure here.
I have no idea how you would describe 2007-2008 as the most significant economic event of the previous years. It's a minor blip at most.
Maybe it's just because I'm not in the US right now, but to me this seems far more significant:
https://s3.amazonaws.com/content.washingtonexaminer.biz/web-...
This is also something pretty significant, and predicted quite nicely by economics: https://qph.ec.quoracdn.net/main-qimg-a9c9410604877c7529d1ea...
I remember my high-school chemistry teacher saying "don't tell the physics teacher that chemistry is just a highly specialised branch of physics!". It's the same with economics and sociology.
His theories on the Protestant ethic are controversial[1], but hardly "thoroughly debunked." As far as the Frankfurt School, uh, who cares? They drew from many political and social philosophies (including Marx who we often find at odds with Weber). It just seems completely uncharitable and tangential to bring it up.

Might also be good to mention the Nobel prize for economics is given by a Swedish bank, not by the Nobel committee.
That said, it is administered and nominations / selections go through the Swedish Academy of Sciences, and it is most certainly considered by the Nobel Foundation as among its prizes.
I'm using it here to note less an agreement with (all) the economists cited here, and far more to note that, whether I find their economics advisible or not (some I do, some I don't), this is a list accepted by both economists and the general scientific community as exemplars of the field, and they are exceedingly strongly critical of elements of the orthodoxy.
Not necessarily the same elements. But strongly critical all the same.
If you're looking for a strong criticism of the Nobel Prize in Economics, I strongly recommend reading F.A. Hayek's acceptance speech on that score, which manages simultaneously to question economics and the prize itself, whilst defending it by numerous strongly counterfactual arguments in my view, Hayek being among those I otherwise have strong reservations for.

* The Nobel memorial prize for economics is indeed given by a Nobel Committee[1] of the Swedish Royal Academy of Sciences, just like the natural science and medicine prizes.
* It has been endowed by the Swedish Riksbank, which is a central bank and part of the Swedish government equivalent to the Federal Reserve in the US. If the importance of the difference between "a Swedish bank" and "the Swedish central bank" is not apparent to you, you should read up on it.

Critiques of efficient and rationale markets by Arrow and Stiglitz come to mind in the latter, as well as much to call into question rational actor theories. There's been significant work since the 1950s on information in economics, mostly concerning risks and asymmetries. I'm seeing a further area that may be available for development by finding an underlying mechanism to Gresham's Law, which seems to me to underly a number of further interesting phenomena.
There's also the fundamental misallocation of true and real costs in natural resource economics, based on a series of decisions tacitly made in the period 1880 - 1940, roughly, many of which turn out to have little bearing on reality.
The failure of economics to account properly for the role of energy (there are those who have: R.U. Ayres and Charles A.S. Hall among them), combined with the misattribution of fossil energy costs, is particularly pronounced and makes a mockery of virtually all present pricing models.
These all fall within the domain of micro.
Problems within energy, healthcare, housing, education, and manufacturing sectors are all concerned with microeconomic factors.
Philip Mirowski's More Heat than Light and numerous of Ha-Joon Chang's works address microeconomic conundrums.

Amusingly, I've noticed that most HR managers have psychology degrees. I've wondered: What if HR managers had economics degrees. Would we be paid more?
When I was a manager, I received some training from the HR department, and we were constantly reminded that our employees didn't really want to get paid more. This was based on "research." I wondered if this was the result of the researchers simply delivering the result that their patrons wanted to hear.
I've decided to favor an economic view over a psychological one: Be nice to people, of course, but treat them as homo economicus, behaving rationally in regard to their own self interest. While this view isn't proven, I think it's better than making assumptions about their psychological motivations that are likely to be biased by factors such as social class, age, gender, and possibly race and ethnicity.
It is no surprise to any classical economist that actors do not always act rationally and the foundation of microeconomics is not built on the unstable platform of assuming that everyone IS rational; but rather that treating actors AS rational is a just and fair way to act while also removing sources of bias.
It does not mean that rules on how to approach people should NOT be modified via analysis of behavior, but rather that a priori we should assume people act rationally in their own self-interest as a first principle and go from there, not assume that everyone is irrational and create a ten million line case/switch statement.
No, economics is a predictive social science, not a system of moral philosophy; the rational choice model has nothing to do with how it is just and fair to treat people. It was the dominant model because despite being self-evidently not fundamentally correct (it assumes a number of things, like perfect knowledge of future outcomes, that no one believes to be literally true or even plausible) it was believed to be an approximation that would predicted results better than any alternative model available at the time, in general and in a wide array of specific cases.
It's also been my experience that when I hear people talking about one another as irrational, it's never because they're trying to be more respectful, but is invariably in support of patronizing or manipulating people. Nobody has ever used an irrational actor hypothesis to justify paying someone more, or giving them more authority and autonomy.
To me it would seem intuitive to have an additional field or area of focus that emphasizes applying sociological findings to public policy.
W. Brian Arthur has pointed out that virtually all significant economic research explores specific policy questions of the day. Usually with a particular point of view in mind.
The results can be ... amusing.

This is precisely why handing the reins over to sociologists would be dangerous. The concept of "identity" is massively over-valued in our society, with very little coherent critical commentary available. Somehow it's seen as an unassailable, unquestionable truism: every person has an identity, and they build on it throughout their entire life. Giving sociologist-types more power to shape policy will lead to an increase in the acceptance and enforcement of this erroneous thought process.
Erroneous because one's "identity" is, in reality, of extremely limited utility and the source of much suffering: does my identity properly reflect who I really am? Are others being respectful to my identity? Are they behaving correctly toward me considering my identity? Is my identity subject to systematic oppression? Should I change my identity or keep it the same? How many people know about my current identity vs. my precious identity that I promoted for many years?
Spending time ruminating and basing policy on this concept of identity is a huge waste of resources, and what's the outcome? Pure, unadulterated suffering.
Identity has its place as a tool for conducting transactions and working in groups, but sociologists and their ilk have elevated it to an all-encompassing life-defining concern, and that's just not reasonable. Given how much we're already burdening ourselves here in the West with identity politics and other massive wastes of resources, I cringe at the thought of sociologists having MORE power over our lives.
The comments about the social interactions of what are perceived as economic transactions or phenmomena strongly suggests a few differences. The social dislocations caused by job loss, or housing eviction, are specifically mentioned. I'd see far more weight and consideration given both in policy.
How many rich economists are there? How many influential sociologists are there?
I do have a question though: What is the central organising question or theme of sociology?
For economics, I would answer "the allocation of scarce resources to greatest effect". I'm not sure I can come up with a simlar statement for sociology, and online searches over the past few minutes aren't turning up anything strongly resembling such a statement.
I'd say this is the goal of macroeconomics, not the entire discipline. And the application of economic public policy tends to be as psuedoscientific and bias-laden as sociology.
I say this as someone who is strongly educated in economics and worked as a private economist; I have a lot of love for the field in general.
EDIT: The goal of economics, broadly, I think is simply analyzing the allocation of scarce resources across a wide variety of market methods and conditions. Ascribing prescriptive behavior is not something at least half of the discipline is interested in.
I find John Marshall's "ordinary business of life" distressingly vague.
Krugman and Wells (2008) give: "economics is the social science that studies the production, distribution, and consumption of goods and services."
I'll argue you've confused macro with micro: macro deals, generally, with inflation, money supply, and foreign exchange. Micro with market allocations and behaviour (under various degrees of competition, monpoly/monopsony, or oligopoly/oligopsony).
It's not that most economic policy isn't adopted (true -- it turns out there's a whole mess of heterdox economics theory), but that adopted public policy (or far more significantly: legal doctrine) is justified on the basis of some economic theory or another.
There's a camp of economists who are particularly capable of developing policy either specifically to, or which incidentally, supports various viewpoints.
See as a classic instance, what Adam Smith actually wrote, vs. what he's presented as writing by such influence-peddlers as the Mont Pelerin Society / Atlas Network disinformation industrial complex.
This statement is based on a study I made by myself using a representative sample: I have 3 sociology PHDs in my team.
