When I showed my wife Raelin's (2000: 98) ladder of inference, she replied that this is much more her way of learning than memorising or having things hammered into her brain—memorising does not work for me! There are many people that much rather learn by engaging and figuring things out, consulting resources as and when necessary.
When I did a search for a picture of a ladder I found numerous ladders of interference, for example:
- Ladder of inference model from Peter Senge's (1994) 5th Discipline Fieldbook.
- Also called by some the ladder of influence or even ladder of innocence.
- Some give the ladder of inference six steps above the surface it is standing on.
- The ladder of inference is regarded as one of the most effective tools in understanding and explaining why we so often get into conflict and fail to get resolution—it was originally articulated by Chris Argyris (acknowledged by Raelin as work-based learning tutor, for his intellectual stimulation) and popularized in Peter Senge.
- William Goelkel emphasise, in the PM Notebook, that we make decisions and take action based on what we consider to be obvious truths based on objective data, however, the problem is the data is often selected to conform to our beliefs—not truths and often not obvious to others—a feedback loop is therefore important.
This four-step ladder is available in 12 colours, with a no handrail, a left, a right or both-sides handrails.
Raelin's (2000: 98) ladder of inference comprise:
Step 4: Take action.
Step 3: Draw inferences.
Step 2: Interpret data.
Step 1: Select data.
Surface: Observe available data.
I further found this very interesting (to me) four step rock climbing device and numerous other gadgets.
