@J3ro3nJ gave me this hint for a new myth, the 70-20-10 rule. We would only learn 10% from the formal learning situation, 20% through others and 70% through experience and practice. Check this video for some animated explanation:
Informal learning: 70-20-10. Does informal learning exist? Folks generally would say yes. But where did the ratio come from and what does it mean? It basically comes from our old Greek friend Archimedes. Then there was an academic, Allen Tough, who in the 1960s used the iceberg as metaphor, and somehow it got popularized as being a formula. Archimedes demonstrated why most of the iceberg is below the surface, and that is where the numbers come from. Think about it: what is the ratio? Is it hours? Compensation? How was it empirically studied? It’s like that old game — telephone. Someone took a conceptual metaphor and then made a misguided inference.
The 70/20/10 Model is a Learning and Development model based on research by Michael M. Lombardo and Robert W. Eichinger for the Center for Creative Leadership. The concept states that development typically begins with realization of a need and motivation to do something about it, and that a blend of different learning approaches “in concert” can provide powerful learning. Lombardo and Eichinger stated that “the odds are that development will be”
This last phrase is quite careful, not really saying it is so, but it could probably be. But this is normal, as scientists are most of the time quite careful in what they state (in my humble opinion, I could be wrong ;) ).
But there is one thing for sure: this statement is about the education of leaders.
“The 70-20-10 rule emerged from 30 years of CCL’s Lessons of Experience research, which explores how executives learn, grow and change over the course of their careers.
The underlying assumption is that leadership is learned. We believe that today, even more than before, a manager’s ability and willingness to learn from experience is the foundation for leading with impact.” (source)
And this is already a big warning light, because can we transfer this insight to other people? Maybe this is the case for potential leaders, but not for people like you and me?
Don Clarck states about this:
“Some have been calling for 70-20-10 to be the new learning model for across the organization, however, since is a prescriptive remedy for developing managers to senior and executive positions, it does not mean that it is a useful model for developing skills in the daily learning and work flows that takes place within organizations because it is being applied in an entirely different context than what it was designed for.” (source)
My biggest warning light is that I couldn’t find any peer reviewed scientific proof about this rule, for sure no proof for successful transfer. Of course I’m just human and could have been overlooking so every clues towards research is more than welcome!
Still… those very neat percentages… Strange, I never get those when I’m doing statistics?
