No. Evidence rarely gives you The Answer but helps you make better-informed decisions](https://reader035.vdocuments.site/reader035/viewer/2022063010/5fc28631cc0d714b7a690f1c/html5/thumbnails/2.jpg)

The underlying simple and modest logic of evidence-based practice1. Practitioners in any field routinely make
decisions and judgements (e.g., about interventions)
2. Those decisions are based on evidence (information) of various and many types
3. Using only a little evidence or evidence that is not relevant or valid is likely to produce poorer decisions and poorer outcomes
4. Using more and more relevant and valid evidence is likely to produce better decisions and outcome

But what happens in HR? For example… Decisions are based on evidence to some extent
but other influences dominate (later) Training and CPD of HR practitioners does not
develop skills for evidence-based practice HR practice not much influenced by research Internal HR data may be low quality, limited, hard
to understand, and poorly analyzed Few incentives for HR to use research and
evidence (including academic evidence) in their practice
Evaluations of HR interventions rare

Who thinks it’s a problem?
Some academics (e.g., Rousseau, Pfeffer, Rynes)
Some practitioners
And some commentators

Where did the idea of evidence-based practice come from?
What field of practice is this describing?– the relevance, quality and applicability of
research is questionable– practice is being driven more by fads and
fashions than research– many practices are doing more harm than good

Where did the idea of evidence-based practice come from?
It is describing medicine 20 years ago (and still somewhat accurate today)
1991/2 British Medical Journal editorials– Only 15–20% of medical interventions were
supported by solid medical evidence– Many practices do more harm than good– Started an evidence-based practice ‘movement’ in
medicine
Now many fields: Education, policing, social care, and most recently management

What is the challenge? All practitioners always use evidence to make
decisions Main problem is the nature, quantity and quality
of that evidence (intuition, common sense, experience, power, custom and practice, fashion, mimicry)
How can practitioners (in this case HR) start to use more and better quality evidence in their decision-making?
This is the challenge evidence-based practice was designed to overcome

What is Evidence-Based Management (EBMgt)?
Evidence-based management is about making decisions through the conscientious, explicit, and judicious use of four sources of information: (1) practitioner expertise and judgment, (2) evidence from the local context, (3) a critical evaluation of the best available research evidence, and (4) the perspectives of those people who might be affected by the decision. (Briner, Denyer, Rousseau, 2009)

Example: Evidence-Based absence management
Element 1: Practitioner expertise and judgement
Have I seen this before? What happened then? What are my beliefs about the causes of absence? What’s worked in the past and why? What do I think are the causes and possible solutions?
Element 2: Evidence from the local context What actually is the absence rate? What type of absences and where? What are local explanations for absence? What absence management is currently in place and is it
working?

Example: Evidence-Based absence management
Element 3: Critical evaluation of best available research evidence
What are the average rates of absence in my sector and location – is the absence rate here ‘high’?
What does systematically reviewed research evidence suggest to be the major causes of absence?
How relevant and applicable is that evidence here?Element 4: Perspectives of those who may be affected by intervention decision
How do employees feel about the proposed interventions? Do they see downsides or unintended negative
consequences? How do managers feel about these interventions?

What is evidence-based practice? Some misconceptions and myths
Evidence means quantitative ‘scientific’ evidence.No. Evidence in general just means information – like the use of ‘evidence’ in legal settings – anything might count if it’s valid and relevant.
Evidence-based practice means practitioners cannot or should not use their professional expertise. No. Expertise is another form of knowledge which can be as valid or relevant as any other. And expertise is necessary to apply evidence.
Evidence can prove things. No. Just probabilities or indications based on limited information and situations.
Evidence tells you the truth about things. No. Truth is a whole different thing. 12

What is evidence-based practice? Some misconceptions and myths
New exciting single ‘breakthrough’ studies provide the best evidence. No. It’s about what a body of research is suggesting.
Collecting valid and relevant evidence gives you The Answer to The Problem. No. Evidence rarely gives you The Answer but helps you make better-informed decisions.
Doing evidence-based practice means doing what the research evidence tells you works. No. Research evidence is just one of four sources of evidence. Evidence-based practice is about practice not research. Evidence doesn’t speak for itself or do anything.

What is evidence-based practice? Some misconceptions and myths
If you don’t have the evidence you can’t do anything. No. But you practice explicitly knowing this. It’s not about perfection or a completely knowable world.
Experts (e.g., consultants, experts and management school professors) know all about the evidence so you just need to ask them. Rarely true. Experts are invariably biased, have limited knowledge and have vested interests (particularly if their expertise is related to their power or other resources). We need to make our own judgements and overcome “trust me I’m a doctor”-type deference.

It is not weird to use evidence in everyday life
Which film shall I watch this weekend?
Which hotel shall I book in a city I’ve never been to before?
What kind of camera should I buy?
Which school is best for my children?
Which washing machine is best?

So it’s not weird to use evidence in everyday life – but is it weird in organizational life?
HR managers (and organizations) are generally supposed to use evidence to make decisions and do use some evidence but
HR managers are not trained to do this – and other things drive decisions

Why does everyone need evidence-based thinking?
A bat and ball cost one pound and ten pence. The bat costs a pound more than the ball. How much does the ball cost?

Why does everyone need evidence-based thinking?
In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Error and biases in problem-solving and decision-making – some examples Confirmation bias: Tendency to interpret and search for information
consistent with one’s prior beliefs
Mere exposure effect: Tendency to develop a preference for things which we have become more familiar with
Hindsight bias: Tendency to see past events as being more predictable than they were before the event occurred
Loss aversion: Tendency to prefer avoiding losses than to acquiring gains
Anchoring effect: Tendency to rely too heavily or over-emphasize one piece of information (e.g., restaurant wine lists, large reductions in price in sales)
Framing effect: Drawing different conclusions from exactly the same information presented in different ways (e.g., would you prefer a ready meal that’s “85% fat free” or “15% fat”?)
Meta-cognitive bias: The belief we are immune from such biases24

25
Why do managers in particular need evidence-based thinking?
Reason 1: Management fads and fashions (and quick fixes)
Reason 2: The role of consultants and consultancies (as fashion setters and fashion suppliers)
Reason 3: The role of power and politics in managerial career success

How are fads a problem? (Donaldson & Hilmer, 1998)
“The main problem…is their lack of any solid intellectual foundation. Implicit in each fad is a cause effect statement that is rarely made explicit and never properly supported.”
“…management needs to evolve a sound body of knowledge and clear language that will assist members of the profession to reason cogently. Faddism is the enemy of this professionalism.”

36
How to spot a likely fad
Buzzy and exciting
Massive claims with no good quality supporting evidence
Involve management gurus and academic superstars
It’s all good! No downsides considered
Presented as universal panacea – work everywhere for everything for everyone
Use of unverifiable anecdotes and success stories (usually from big well-known companies whose success is attributed to fad with no good evidence)
Involve new words which don’t actually describe anything new - e.g., analytics (analysis), big data (data), talent (people), human capital (people) 36

37
Related concept of the quick fix Focus on style and presentation not content or
process Not be evaluated Not be as quick as had been hoped Not be effective so followed by another quick fix Become subject to organizational amnesia* Can be career-enhancing for managers (e.g.,
issue selling, kick-ass CEOs)
*Kitchen equipment analogy

So why are fads and fashions followed? Promise to deliver a lot and fast
Appear simple
New and shiny
Will make everything alright
Help contain anxieties around intractable problems
Help user feel effective and cutting edge
Seems very ‘human’ to want to find quick, easy answers that other people are adopting too
Evidence-based management not really much of a fad using these criteria

Reason 2: The role of consultants and consultancies
Translators of research evidence?
Brokers or sellers of management fads and fashions?
External objective advisors?
Repositories of experience and wisdom?
Change agents?
Ways of justifying and externalizing unpopular decisions?

Pfeffer & Sutton (2006)
“…consultants and others who sell ideas and techniques are always rewarded for getting work, only sometimes rewarded for doing good work, and hardly ever rewarded for whether their advice actually enhances performance.
The incentives are often even more perverse than that, because if a client company’s problems are only partly solved that leads to more work for the consulting firm.”

What are the incentives for consultancies to be evidence-based?
Get the work, get more work, and keep getting work (so depends almost entirely on what clients want)– Persuade (may not take much) clients they need some
new thing, idea, technique, approach– Sell them the relevant product or service or intervention
based on that idea, technique or approach– Saturate the market until everyone’s bought it– Invent or borrow new ideas, techniques and
approaches clients do not yet use– Sell them the relevant product or service or intervention– Repeat

Reason 3: Power, politics and careers: Why do people get to senior positions? Because they.. Do what works? But very few evaluations so how does anyone
know?
Get things done and make things happen? Certainly.
Do not rock the boat? Probably.
Work hard? Likely.
Have strong need for achievement/recognition? Certainly.
Obey orders? Probably.
Solve problems? Certainly, but often presenting or political problems.
Make their bosses look good? Often.
Cover their backs, avoiding blame or mistakes: Often.53

Huge incentives and punishments around conventional thinking, fads, fashions And there we see the power of any big
managerial idea [including management fads]. It may be smart, like quality, or stupid, like conglomeration. Either way, if everybody's doing it, the pressure to do it too is immense. If it turns out to be smart, great. If it turns out to be stupid, well, you were in good company and most likely ended up no worse off than your competitors. Your company's board consists mostly of CEOs who were probably doing it at their companies. How mad can they get?

Huge incentives and punishments around conventional thinking, fads, fashions
The true value of conventional management wisdom [current fashion] is not that it's wise or dumb, but that it's conventional. It makes one of the hardest jobs in the world, managing an organization, a little easier. By following it, managers everywhere see a way to drag their sorry behinds through another quarter without getting fired. And isn't that, really, what it's all about?
(Colvin, 2004, Fortune)

What are the incentives for HR managers to be evidence-based?
Not rewarded for doing what ‘works’ – few evaluations
Speed and action valued more highly than accuracy and analysis
Managing and understanding power and politics to get things done more valued than understanding and using evidence to make decisions

So why does HR need evidence-based management?
General cognitive biases that limit decision-making and judgement
Management fads, fashions and quick fixes
Consultants/advisors/fad vendors
Power and politics that determine seniority

How to become a little more evidence-based [2]
View it as personal and professional and organizational development and learning
Ask lots of questions (critical thinking skills)
Develop decision aids, tools, processes, frameworks
Develop healthy scepticism towards fads, miracle ‘cures’, breakthrough studies, gurus and experts
Accept ignorance and limits of all forms of knowledge and evidence
It’s about values: If you’re not evidence-based, what are you?
