CORE DEFINITION

The expertise reversal effect is the finding that instructional support which benefits novices, such as detailed guidance and worked examples, becomes a cognitive load and an active hindrance to more knowledgeable learners, whose results decline when it is imposed on them. Its proposition is that effective instructional support must be matched to the learner's level and removed in time, because the very support that rescues a beginner will burden an expert.

The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.

Curse of Knowledge

The curse of knowledge, also called the curse of expertise or expert's curse, is a cognitive bias that occurs when a person who has specialized knowledge assumes that others share in that knowledge.
