CORE DEFINITION

Consumers tend to choose products with the most features before purchase (to "cover all bases"), but after use, complex features can lead to decreased satisfaction (because they are hard to learn or unnecessary), resulting in fatigue.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Balance purchase desire and usage experience. It reveals that "buying" and "using" are two separate psychological processes. As a product manager, restrain the impulse to pile on features; as a consumer, be wary of paying for "bells and whistles" you'll never use.

anchor

Anchor fast decisions

Before purchase, consumers favor products with many features; after use, complex features bring learning costs and frustration, reducing satisfaction. Buying and using are separate psychological processes.
