CORE DEFINITION

When people know that certain information can be easily found online (e.g., via Google search), the brain automatically reduces its memory investment in that information, instead remembering 'where to find it'. We are transitioning from 'content memorizers' to 'index memorizers'.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The cost of an external brain. - This is not inherently bad (it frees up brain memory), but the risk is that the internalization of knowledge is interrupted. If you only 'know where to search' without 'loading the core logic into your head', you cannot engage in higher-order thinking.

anchor

Anchor fast decisions

Knowing that information can be retrieved at any time, the brain remembers less content and instead remembers the 'location' (index), shifting from content memorizer to index memorizer; the external brain frees up memory but interrupts internalization.

MINIMUM ACTION

In progress 0/2

Practice this model in one real situation:

Distinguish between information that should be 'indexed' and that which should be 'internalized' - core logic/frameworks should be loaded into the brain, while details can be externalized
regularly engage in recall and retelling without search to prevent hollowing out.
