The Translation Fallacy

If you have ever been unlucky enough to attend a large gathering of strategy academics – as I have, many times – it may have struck you that at some point during such a feast (euphemistically called “conference”), the subject matter would turn to talks of “relevance”. It is likely that the speakers were a variety of senior and grey – in multiple ways – interchanged with aspiring Young Turks. A peculiar meeting of minds, where the feeling might have dawned on you that the senior professors were displaying a growing fear of bowing out of the profession (or life in general) without ever having had any impact on the world they spent a lifetime studying, while the young assistant professors showed an endearing naivety believing they were not going to grow up like their academic parents.

And the conclusion of this uncomfortable alliance – under the glazing eyes of some mid-career, associate professors, who could no longer and not yet care about relevance – will likely have been that “we need to be better at translating our research for managers”; that is, if we’d just write up our research findings in more accessible language, without elaborating on the research methodology and theoretical terminology, managers would immediately spot the relevance in our research and eagerly suck up its wisdom.

And I think that’s bollocks.

I don’t think it is bollocks that we – academics – should try to write something that practicing managers are eager to read and learn about; I think it is bollocks that all it needs is a bit of translation in layman’s terms and the job is done.

Don’t kid yourself – I am inclined to say – it ain’t that easy. In fact, I think there are three reasons why I never see such a translation exercise work.

1. Ignorance

I believe it is an underestimation of the intricacies of the underlying structure of a good managerial article, and the subtleties of how to convincingly write for practicing managers. If you’re an academic, you might remember that in your first year as a PhD student you had the feeling it wasn’t too difficult to write an academic article such as the ones you had been reading for your first course, only to figure out, after a year or two of training, that you had been a bit naïve: you had been (blissfully) unaware of the subtleties of writing for an academic journal; how to structure the arguments; which prior studies to cite and where; which terminology to use and what to avoid; and so on. Well, good managerial articles are no different; if you haven’t developed the skill yet to write one, you likely don’t quite realise what it takes.

2. False assumptions

It also seems that academics, wanting to write their first managerial piece, immediately assume they have to be explicitly prescriptive, and tell managers what to do. And the draft article – invariably based on “the five lessons coming out of my research” – would indeed be fiercely normative. Yet, those messages often seem impractically precise and not simple enough (“take up a central position in a network with structural holes”) or too simple to have any real use (“choose the right location”). You need to capture a busy executive’s attention and interest, giving them the feeling that they have gained a new insight into their own world by reading your work. If that is prescriptive: fine. But often precise advice is precisely wrong.

3. Lack of content

And, of course, more often than not, there is not much worth translating… Because people have been doing their research with solely an academic audience in mind – and the desire to also tell the real world about it only came later – it has produced no insight relevant for practice. I believe that publishing your research in a good academic journal is a necessary condition for it to be relevant; crappy research – no matter how intriguing its conclusions – can never be considered useful. But rigour alone, unfortunately, is not a sufficient condition for it to be relevant and important in terms of its implications for the world of business.

“Can’t Believe It" 2

My earlier post – “can’t believe it” – triggered some bipolar comments (and further denials); also to what extent this behaviour can be observed among academics studying strategy. And, regarding the latter, I think: yes.
The denial of research findings obviously relates to confirmation bias (although it is not the same thing). Confirmation bias is a tricky thing: we – largely without realising it – are much more prone to notice things that confirm our prior beliefs. Things that go counter to them often escape our attention.

Things get particularly nasty – I agree – when we do notice the facts that defy our beliefs but we still don’t like them. Even if they are generated by solid research, we’d still like to find a reason to deny them, and therefore see people start to question the research itself vehemently (if not aggressively and emotionally).

It becomes yet more worrying to me – on a personal level – if even academic researchers themselves display such tendencies – and they do. What do you think a researcher in corporate social responsibility will be most critical of: a study showing it increases firm performance, or a study showing that it does not? Whose methodology do you think a researcher on gender biases will be more inclined to challenge: a research project showing no pay differences or a study showing that women are underpaid relative to men?

It’s only human and – slightly unfortunately – researchers are also human. And researchers are also reviewers and gate-keepers of the papers of other academics that are submitted for possible publication in academic journals. They bring their biases with them when determining what gets published and what doesn’t.

And there is some evidence of that: studies showing weak relationships between social performance and financial performance are less likely to make it into a management journal as compared to a finance journal (where more researchers are inclined to believe that social performance is not what a firm should care about), and perhaps vice versa.

No research is perfect, but the bar is often much higher for research generating uncomfortable findings. I have little doubt that reviewers and readers are much more forgiving when it comes to the methods of research that generates nicely belief-confirming results. Results we don’t like are much less likely to find their way into an academic journal. Which means that, in the end, research may end up being biased and misleading.

“Can’t Believe It” (we deny research findings that defy our beliefs)

So, I have been running a little experiment on twitter. Oh well, it doesn’t really deserve the term “experiment” – at least in an academic vocabulary – because there certainly are no treatment effects or control groups. It does deserve the term “little” though, because there are only four observations.

My experiment was to post a few recent findings from academic research that some might find mildly controversial or – as it turns out – offending. These four hair raising findings were 1) selling junk food in schools does not lead to increased obesity, 2) family-friendly workplace practices do not improve firm performance (although they do not decrease them either), 3) girls take longer to heal from concussions, 4) firms headed up by CEOs with broader faces show higher profitability.

Only mildly controversial I’d say, and only to some. I was just curious to see what reactions it would trigger. Because I have noticed in the past that people seem inclined to dismiss academic evidence if they don’t like the results. If the results are in line with their own beliefs and preconceptions, its methods and validity are much less likely to be called stupid.  

Selling junk food in schools does not lead to increased obesity is the finding of a very careful study by professors Jennifer Van Hook and Claire Altman. It provides strong evidence that selling junk food in schools does not lead to more fat kids. One can then speculate why this is – and their explanation that children’s food patterns and dietary preferences get established well before adolescence may be a plausible one – but you can’t deny their facts. Yet, it did lead to “clever” reactions such as “says more about academic research than junk food, I fear...”, by people who clearly hadn’t actually read the study.

Family-friendly workplace practices do not improve firm performance is another finding that is not welcomed by all. This large and competent study, by professors Nick Bloom, Toby Kretschmer and John van Reenen, was actually read by some, be it clearly without a proper understanding of its methodology (which, indeed, it being an academic paper, is hard to fully appreciate without proper research methodology training). It led to reactions that the study was “in fact, wrong”, made “no sense”, or even that it really showed the opposite; these silly professors just didn’t realise it.

Girls take longer to heal from concussions is the empirical fact established by Professor Tracey Covassin and colleagues.. Of course there is no denying that girls and boys are physiologically different (one cursory look at my sister in the bathtub already taught me that at an early age), but the aforementioned finding still led to swift denials such as “speculation”!

That firms headed up by CEOs with broader faces achieve higher profitability – a careful (and, in my view, quite intriguing) empirical find by my colleague Margaret Ormiston and colleagues – triggered reactions such as “sometimes a study tells you more about the interests of the researcher, than about the object of the study” and “total nonsense”. 

So I have to conclude from my little (academically invalid) mini-experiment that some people are inclined to dismiss results from research if they do not like them – and even without reading the research or without the skills to properly understand it. In contrast, other, nicer findings that I had posted in the past, which people did want to believe, never led to outcries of bad methodology and mentally retarded academics and, in fact, were often eagerly retweeted.

We all look for confirmation of our pre-existing beliefs and don’t like it much if these comfortable convictions are challenged. I have little doubt that this also heavily influences the type of research that companies conduct, condone, publish and pay attention to. Even if the findings are nicer than we preconceived (e.g. the availability of junk food does not make kids consume more of it), we prefer to stick to our old beliefs. And I guess that’s simply human; people’s convictions don’t change easily.

Let’s face it: in most industries, firms pretty much do the same thing


In the field of strategy, we always make a big thing out of differentiation: we tell firms that they have to do something different in the market place, and offer customers a unique value proposition. Ideas around product differentiation, value innovation, and whole Blue Oceans are devoted to it. But we also can’t deny that in many industries – if not most industries – firms more or less do the same thing.

Whether you take supermarkets, investment banks, airlines, or auditors, what you get as a customer is highly similar across firms.

1. Ability to execute: What may be the case, is that despite doing pretty much the same thing, following the same strategy, there can be substantial differences between the firms in terms of their profitability. The reason can lie in execution: some firms have obtained capabilities that enable them to implement and hence profit from the strategy better than others. For example, Sainsbury’s supermarkets really aren’t all that different from Tesco’s, offering the same products at pretty much the same price in pretty much the same shape and fashion in highly identical shops with similarly tempting routes and a till at the end. But for many years, Tesco had a superior ability to organise the logistics and processes behind their supermarkets, raking up substantially higher profits in the process.

2. Shake-out: As a consequence of such capability differences – although it can be a surprisingly slow process – due to their homogeneous goods, we may see firms start to compete on price, margins decline to zero, and the least efficient firms are pushed out of the market. And one can hear a sigh of relief amongst economists: “our theory works” (not that we particularly care about the world of practice, let alone be inclined to adapt our theory to it, but it is more comforting this way).

3. A surprisingly common anomaly? But it also can’t be denied that there are industries in which firms offer pretty much the same thing, have highly similar capabilities, are not any different in their execution, and still maintain ridiculously high margins for a sustained period of time. And why is that? For example, as a customer, when you hire one of the Big Four accounting firms (PwC, Ernst & Young, KPMG, Deloitte), you really get the same stuff. They are organised pretty much the same way, they have the same type of people and cultures, and have highly similar processes in place. Yet, they also (still) make buckets of money, repeatedly turning and churning their partners into millionaires.

“But such markets shouldn’t exist!” we might cry out in despair. But they do. Even the Big Four themselves will admit – be it only in covert private conversations carefully shielding their mouths with their hands – that they are really not that different. And quite a few industries are like that. Is it a conspiracy, illegal collusion, or a business X file?

None of the above I am sure, or perhaps a bit of all of them… For one, industry norms seem to play a big role in much of it: unwritten (sometimes even unconscious), collective moral codes, sometimes even crossing the globe, in terms of how to behave and what to do when you want to be in this profession. Which includes the minimum price to charge for a surprisingly undifferentiated service.

A good fight clears the mind: On the value of staging a debate

I always enjoy witnessing a good debate. And I mean the type of debate where one person is given a thesis to defend, while the other person speaks in favour of the anti-thesis. Sometimes – when smart people really get into it – seeing two debaters line up the arguments and create the strongest possible defence can really clarify the pros and cons in my mind and hence make me understand the issue better.

For example – be it one in a written format – recently my good friend and colleague at the London Business School, Costas Markides, was asked by Business Week to debate the thesis that “happy workers will produce more and do their jobs better”. Harvard’s Teresa Amabile and Steven Kramer had the (relatively easy) task of defending the “pro”. I say relatively easy, because the thesis seems intuitively appealing, it is what we’d all like to believe, and they have actually done ample research on the topic.

My poor London Business School colleague was given the hapless task to defend the “con”: “no, happy workers don’t do any better”. Hapless indeed.

In fact, in spite of receiving some hate mail in the process, I think he did a rather good job. I am giving him the assessment “good” because indeed he made me think. He argues that having happy, smiley employees all abound might not necessarily be a good sign, because it might be a signal that something is wrong in your organisation, and you’re perhaps not making the tough but necessary choices.

As said, it made me think, and that can’t be bad. Might we not be dealing with a reversal of cause and effect here? Meaning: well-managed companies will get happy employees, but that does not mean that choosing to make your employees happy as a goal in and of itself will get you a better organisation? At least, it is worth thinking about.

In spite that perhaps to you it might seem a natural thing to have in an academic institution – a good debate – it is actually not easy to organise one in business academia. Most people are simply reluctant to do it – as I found out organising our yearly Ghoshal Conference at the London Business School – and perhaps they are right, because even fewer people are any good at it.

I guess that is because, to a professor, it feels unnatural to adopt and defend just one side of the coin, because we are trained to be nuanced about stuff and examine and see all sides of the argument. It is also true that (the more naïve part of) the audience will start to associate you with that side of the argument, “as if you really meant it”. Many of the comments Costas received from the public were of that nature, i.e. “he is that moronic guy who thinks you should make your employees unhappy”. Which of course is not what he meant at all. Nor was it the purpose of the debate.

Yet, I also think it is difficult to find people willing to debate a business issue because academics are simply afraid to have an opinion. We are not only trained to examine and see all sides of an argument, we are also trained to not believe in something – let alone argue in favour of it – until there is research that produced supportive evidence for it. In fact, if in an academic article you would ever suggest the existence of a certain relationship without presenting evidence, you’d be in for a good bellowing and a firm rejection letter. And perhaps rightly so, because providing evidence and thus real understanding is what research is about.

But, at some point, you also have to take a stand. As a paediatric neurologist once told me, “what I do is part art, part science”. What he meant is that he knew all the research on all medications and treatments, but at the end of the day every patient is unique and he would have to make a judgement call on what exact treatment to prescribe. And doing that requires an opinion.

You don’t hear much opinion coming from the ivory tower in business academia. Which means that the average business school professor does not receive much hate mail. It also means he doesn’t have much of an audience outside of the ivory tower.

Research by Mucking About

I am a long standing fan of the Ig Nobel awards. The Ig Nobel awards are an initiative by the magazine Air (Annals of Improbable Research) and are handed out on a yearly basis – often by real Nobel Prize winners – to people whose research “makes people laugh and then think” (although its motto used to be to “honor people whose achievements cannot or should not be reproduced" – but I guess the organisers had to first experience the “then think” bit themselves).

With a few exceptions they are handed out for real research, done by academics, and published in scientific journals. Here are some of my old time favourites:
• BIOLOGY 2002, Bubier, Pexton, Bowers, and Deeming.“Courtship behaviour of ostriches towards humans under farming conditions in Britain” British Poultry Science 39(4)
• INTERDISCIPLINARY RESEARCH 2002. Karl Kruszelnicki (University of Sydney). “for performing a comprehensive survey of human belly button lint – who gets it, when, what color, and how much”
• MATHEMATICS 2002. Sreekumar and Nirmalan (Kerala Agricultural University). “Estimation of the total surface area in Indian Elephants” Veterinary Research Communications 14(1)
• TECHNOLOGY 2001, Jointly to Keogh (Hawthorn), for patenting the wheel (in 2001), and the Australian Patent Office for granting him the patent.
• PEACE 2000, the British Royal Navy, for ordering its sailors to stop using live cannon shells, and to instead just shout “Bang!”
• LITERATURE 1998, Dr. Mara Sidoli (Washington) for the report “farting as a defence against unspeakable dread”. Journal of analytical psychology 41(2)

To the best of my knowledge, there is (only) one individual who has not only won an Ig Nobel Award, but also a Nobel Prize. That person is Andre Geim. Geim – who is now at the University of Manchester – for long held the habit of dedicating a fairly substantial proportion of his time to just mucking about in his lab, trying to do “cool stuff”. In one of such sessions, together with his doctoral student Konstantin Novoselov, he used a piece of ordinary sticky tape (which allegedly they found in a bin) to peel off a very thin layer of graphite, taken from a pencil. They managed to make the layer of carbon one atom thick, inventing the material “graphene”.

In another session, together with Michael Berry from the University of Bristol, he experimented with the force of magnetism. Using a magnetized metal slab and a coil of wire in which a current is flowing as an electromagnet, they tried to make a magnetic force that exactly balanced gravity, to try and make various objects “float”. Eventually, they settled on a frog – which, like humans, mostly consists of water – and indeed managed to make it levitate.

The one project got Geim the Ig Nobel; the other one got him the Nobel Prize.

“Mucking about” was the foundation of these achievements. The vast majority of these experiments doesn’t go anywhere; some of them lead to an Ig Nobel and makes people laugh; others result in a Nobel Prize. Many of man’s great discoveries – in technology, medicine or art – have been achieved by mucking about. And many great companies were founded by mucking about, in a garage (Apple), a dorm room (Facebook), or a kitchen and a room above a bar (Xerox).

Unfortunately, in strategy research we don’t muck about much. In fact, people are actively discouraged from doing so. During pretty much any doctoral consortium, junior faculty meeting, or annual faculty review, a young academic in the field of Strategic Management is told – with ample insistence – to focus, figure out in what subfield he or she wants to be known, “who the five people are that are going to read your paper” (heard this one in a doctoral consortium myself), and “who your letter writers are going to be for tenure” (heard this one in countless meetings). The field of Strategy – or any other field within a business school for that matter – has no time and tolerance for mucking about. Disdain and a weary shaking of the head are the fates of those who try, and step off the proven path in an attempt to do something original with uncertain outcome: “he is never going to make tenure, that’s for sure”.

And perhaps that is also why we don’t have any Nobel Prizes.

“The Best Degree for Start-up Success”

“So you want to start a company. You've finished your undergraduate degree and you're peering into the haze of your future. Would it be better to continue on to an MBA or do an advanced degree in a nerdy pursuit like engineering or mathematics? Sure, tech skills are hugely in demand and there are a few high-profile nerd success stories, but how often do pencil-necked geeks really succeed in business? Aren't polished, suited and suave MBA-types more common at the top? Not according to a recent white paper from Identified, tellingly entitled "Revenge of the Nerds."

Interested? Yes, it does sound intriguing, doesn’t it? It is the start of an article, written by a journalist, based on a report by a company called “Identified”. In the report, you can find that “Identified is the largest database of professional information on Facebook. Our database includes over 50 million Facebook users and over 1.2 billion data points on professionals’ work history, education and demographic data”.

In the report, based on the analysis of data obtained from Facebook, under the header “the best degree for start-up success”, Identified presents some “definitive conclusions” about “whether an MBA is worth the investment and if it really gets you to the top of the corporate food chain”. Let me no longer hold you in suspense (although I think by now you do see this one coming from a mile or two, like a Harry and Sally romance), the definitive conclusion is: “that if you want to build a company, an advanced degree in a subject like engineering beats an MBA any day”.

So I have read the report…

[insert deep sigh]

and – how shall I put it – I have a few doubts… ( = polite English euphemism)

Although Identified has “assembled a world class team of 15 engineers and data scientists to analyse this vast database and identify interesting trends, patterns and correlations” I am not entirely sure that they are not jumping to a few unwarranted conclusions. ( = polite English euphemism)

So, when they dig up from Facebook all the profiles of anyone listed as “CEO” or “founder”, they find that about ¾ are engineers and a mere ¼ are MBAs. (Actually, they don’t even find that, but let me not get distracted here). I have no quibbles with that; I am sure they do find what they find; after all, they do have “a world class team of 15 engineers and data scientists”, and a fact is a fact. What I have more quibbles with is how you get from that to the conclusion that if you want to build a company, an advanced degree in a subject like engineering beats an MBA any day.

Perhaps it may seem obvious and a legitimate conclusion to you: more CEOs have an engineering degree than an MBA, so surely getting an engineering degree is more likely to enable you to become a CEO? But, no, that is where it goes wrong; you cannot draw this conclusion from those data. Perhaps “a world class team of 15 engineers and data scientists [able] to analyse this vast database and identify interesting trends, patterns and correlations” are superbly able at digging up the data for you but, apparently, they are less skilled in drawing justifiable conclusions. (I am tempted to suggest that, for this, they would have been better off hiring an MBA, but will fiercely resist that temptation!)

The problem is, what we call, “unobserved heterogeneity”, coupled with some “selection bias”, finished with some “bollocks” (one of which is not a generally accepted statistical term) – and in this case there is lots of it. For example – to start with a simple one – perhaps there are simply a lot more engineers trying to start a company than MBAs. If there are 20 engineers trying to start a company and 9 of them succeed, while there are 5 MBAs trying it and 3 of them succeed, can you really conclude that an engineering degree is better for start-up success than an MBA?

But, you may object, why would there be more engineers who are trying to start a business? Alright then, since you insist, suppose out of the 10 engineers 9 succeed and out of the 10 MBAs only 3 do, but the 9 head $100,000 businesses and the three $100 million ones? Still so sure that an engineering degree is more useful to “get you to the top of the corporate food chain”? What about if the MBA companies have all been in existence for 15 years while all the engineering start-ups never make it past year 2?

And these are of course only very crude examples. There are likely more subtle processes going on as well. For instance, the same type of qualities that might make someone choose to do an engineering degree could prompt him or her to start a company, however, this same person might have been better off (in terms of being able to make the start-up a success) if s/he had done an MBA. And if you buy none of the above (because you are an engineer or about to be engaged to one) what about the following: people who chose to do an engineering degree are inherently smarter and more able people than MBAs, hence they start more and more successful companies. However, that still leaves wide open the possibility that such a very smart and able person would have been even more successful had s/he chosen to do an MBA before venturing.

I could go on for a while (and frankly I will) but I realise that none of my aforementioned scenarios will be the right one, yet the point is that there might very well be a bit going on of several of them. You cannot compare the ventures started by engineers with the ventures headed by MBAs, you can’t compare the two sets of people, you can’t conclude that engineers are more successful founding companies, and you certainly cannot conclude that getting an engineering degree makes you more likely to succeed in starting a business. So, what can you conclude from the finding that more CEOs/founders have a degree in engineering than an MBA? Well… precisely that; that more CEOs/founders have a degree in engineering than an MBA. And, I am sorry, not much else.

Real research (into such complex questions such as “what degree is most likely to lead to start-up success?) is more complex. And so will likely have to be the answer. For some type of businesses an MBA might be better, and for others an engineering degree. And some type of people might be more helped with an MBA, where other types are better off with an engineering degree. There is nothing wrong with deriving some interesting statistics from a database, but you have to be modest and honest about the conclusions you can link to them. It may sound more interesting if you claim that you find a definitive conclusion about what degree leads to start-up success – and it certainly will be more eagerly repeated by journalist and in subsequent tweets (as happened in this case) – but I am afraid that does not make it so.
