LADDER OF INFERENCE
(Senge, Rick Ross,
Fieldbook, 242):

The ladder of inference
explains why most people don’
t usually remember where our
deepest perspectives came
from.  The data is long lost to
memory, after years of
inferential leap.

Before long, we come to think
of our long-standing
assumptions as data,
but we
are actually several steps
removed from data.

Our ability to achieve the
results we truly desire is
eroded by our feelings that:

Our beliefs are the truth
The truth is obvious
Our beliefs are based on real
data
The data we select are the
real data
