Let’s kill a few learning holy cows – 70:20:10 is dead (or at least seriously ill)
Harold Jarche (@hjarche) recently wrote a blog post that contains a number of items I profoundly disagree with, so much so that it’s time for a new blog post from me. I actually agree with many of his conclusions; unfortunately the road Harold takes to get there is filled with potholes.
Starting from the top, those potholes are:
- 80% of learning on the job is informal;
- individual learning in organizations is irrelevant;
- learner-centric learning objectives are not justifiable
I’ll take items two and three first, because the 80:20 ‘pothole’ is more of a bottomless pit and I’ll devote the bulk of this post to it.
Let’s start with: “individual learning in organizations is irrelevant”, the argument being that work is done by teams and networks, therefore the individual is less/not important. Whilst I absolutely support the implication in Harold’s post that context crucial and that none of us exist in a vacuum, I am reminded of one of my favourite quotes (if only I could remember who said it!) “Without people, companies are just depreciating assets”. Organizations don’t learn (sorry Mr. Senge). Teams don’t learn. Networks don’t learn. People learn. People can learn to perform (better) in organizational, network or team contexts; they can even learn in teams, but organizations and teams don’t learn. (we could go off and discuss whether processes and/or culture count as organizational memory, but in both cases they are either created or instantiated by people. Individual learning is it. But context is crucial.
Next one: “learner-centric learning objectives are not justifiable”. Harold argues that learning objectives should be crafted as “the organization will be able to …”, not “the learner will be able to …”. Again, organizations don’t do things. People do. The role of the corporate learning organization is to develop human capability to execute business strategy. A key skill of the members of the training team is therefore to work with business leaders to translate company goals and strategies into objectives that can be achieved via learning. The goal of a learning program should be to “enable [employees/partners/customers...] to achieve [company objective]. Learning objectives should support the program goal.
Finally, let’s talk about the 80% thing (alternatively stated as the 70:20:10 rule – 70% of learning is informal/experiential, 20% comes from mentoring/feedback, and only 10% comes from formal learning). The implication that often follows references to 70:20:10 is that we are wasting resources on formal training, and that social collaboration/informal learning is some sort of nirvana.
I really don’t want to target Harold for this one. He’s simply repeating what many others have said before him. The 70:20:10 mantra has reached almost hysterical levels in corporate learning circles.
But all is not what it seems.
I recently had the privilege to spend a few days at the Wharton Business School at the University of Pennsylvania with a number of academics and a hundred or so senior corporate learning folks like me. We were attending the 2010 Global Leadership Congress organized by the Corporate University Exchange. (Great event, by the way. Thanks Alan and team!) Both prior to and during the event I spent time with Dr Doug Lynch. Doug opened my eyes about a few things, but most notably about 70:20:10.
Doug asked a couple of simple questions: (a) is 70:20:10 true, and (b) if so how do we know? Everyone in the learning space seems to assume (a) is true, but we all get a bit vague about (b). The answer to (b) is almost always “because I read it in ____ (insert your favourite training magazine title here)”. Doug therefore set his post-grad students a simple challenge: find the source of the 70:20:10 concept. The results are at best worrying and at worst frightening. The following is taken from information presented by Doug at the event):
- If you google “70:20:10″ you get 2.25m hits. That’s right, 2.25m. Hits are split between the education model, and the business resource management model of the same name
- “Informal learning” gets you 402,000 hits, as of the time of writing this post.
- 70:20:10 was the subject of the 2009 ASTD study, “Tapping the Potential of Informal Learning” (exec summary PDF here)
- There is even a Wikipedia article
- Informal learning has been covered in just about every training publication and in the mainstream media, including the Harvard Business Review
The problem is that almost no-one, including the Wikipedia article and HRB cites the original research for 70:20:10 applied to education.
So what does the research have to say on 70:20:10?
- If you step away from the mainstream, you get 46,800 hits with in Google Scholar
- If you drill down to what might be called ‘authoritative sources’, things get a little narrower. There are a grand total of 46 EBSCO (Peer reviewed) Articles
- If you examine the peer reviewed articles, there is not one single empirical study that validates 70:20:10
That’s right. Not one. (I hope someone out there can prove me – or rather Doug – wrong on this one)
70:20:10 was never researched; it was conceptualized by Tough in 1968 and put forward as a hypothesis.
Think about it. All of that wild hysteria that has built up around social learning and collaboration? All that time and dollars/pounds/euros you are spending on collaboration systems? Built on a house of cards. Er. Um. Time for a headache pill.
Please don’t get me wrong. I’m as big a supporter of collaborative and experiential learning and the use of social media and web 2.0 tools and techniques for learning as the next person, if not more so.
My engineering background would just like things to be on a bit firmer footing. Any Academics out there up for a challenge?

I wrote “~80%” (not 70-20-10, & please read the previous posts, as this is a blog post, not a thesis)
Sources cited in Jay Cross, Informal Learning, Appendix B (p. 243):
Marcia Connor 2005 75% informal
Bureau of Labor Stats 1996 70% informal
Raybould 2000 85-90% on the job
Dobbs 2000 Ed Dev Center Newton Mass. 1997 70% on job informal
Lloyd 2000 75% informal
eLearning Guild 2005 70% informal
NALL OISE (University of Toronto) 1998 70% informal; from lead researcher, David Livingston, “The major conclusion from this survey is that our organized systems of schooling and continuing education and training are like big ships floating in a sea of informal learning. If these education and training ships do not pay increasing attention to the massive amount of outside informal learning, many of them are likely to sink into Titanic irrelevancy.”
Nick…many claim 70/20/10 as the way…if there is no evidence, let’s go at it…
Nick:
I regard you as an enlightened, thoughtful practitioner of education applied in the corporate world. I have read this blog and am writing in comment.
I believe your assessment of Jarche’s second and third “potholes” is spot on. I share your admonition of Peter Senge (Fifth Discipline (organizational learning), “Organizations don’t learn.” and your assertion “People learn.” I would expand it to people learn from other people. Mentoring would be a useful topic for exploration in a future blog/article. In fact, you might have here the beginning of a series on workplace learning.
Your statement about organizational memory is a relevant, appropriate clarifying follow-on. You could–and should–go off and discuss the crucial nature of organizational memory in another blog/article. Without careful, continuous attention to organizational memory–the collective, captured and applied learning of individuals–the adage about those who ignore history are destined to repeat its mistakes is verified.
Regarding the 80:20/70:20:10 “mantra”, I would offer that searching for its educational-related application probably is not worth the time. I suggest it is simply the application of what is known as the Pareto Principle/Pareto’s Law–Italian economist Vilfredo Pareto, 1906–(the 80:20–actually, mathematically it is 82:18– Rule/the Law of the Vital Few) to this arena. Pareto’s Law is such a commonly used rule-of-thumb in business, it makes sense to me that it got applied to learning.
I hope you will continue to make observations like these; perhaps work them into presentations both at HDS and in public.
I agree with Nick – it amazes me how even seemingly educated and professional people start bleating the 70:20:10 refrain only because the company said it was so. Nobody asks “how do you know?” I once called it a “theory” and got strange looks because everyone knows it is a fact that can’t be questioned. It seems to me these corporate types are trying to turn back our whole enlightenment-generated culture by selling theory as fact. We should always be willing to ask difficult questions when the corporate taliban come forth with the latest ‘facts’ for us to repeat.
Nick,
I think 80/20 is “roughly right”, which is likely good enough for most business executives. I have not seen ANY evidence to indicate that 70-20-10 is anything but good natured guessing from well intentioned practitioners.
Great article Nick,
Alan
