Delmore effect

Self Assessment

The Delmore effect is a cognitive bias where people prefer simple, complete solutions over complex ones.

How it works

This effect operates on the basis that individuals prefer easily digestible information due to limited cognitive resources.

Examples

  • In business, simple strategies are often chosen over complex ones.
  • Students opt for summaries instead of detailed textbooks.
  • Politicians rely on slogans for effective communication.

Consequences

This bias can lead to suboptimal decisions due to the rejection of more complex, potentially better solutions.

Counteracting

  • Promoting critical thinking through education.
  • Highlighting successful complex solutions.
  • Using tools to simplify without losing depth.

Critiques

Simplicity can make information more accessible, critical in high-pressure situations.
