The information ladder is a diagram created by education professor Norman Longworth to describe the stages in human learning. According to the ladder, a learner moves through the following progression to construct "wisdom" at the highest level from "data" at the lowest level:
- Data → Information → Knowledge → Understanding → Insight → Wisdom
Whereas the first two steps can be scientifically exactly defined, the upper parts belong to the domain of psychology and philosophy.
The related model in information science is referred to as DIKW Hierarchy.
