What is the ratchet effect?

• A. The process by which cultural information accumulates over time, increasing in complexity without losing earlier information.
• B. A decrease in cultural complexity over time.
• C. Random fluctuations without accumulation.
• D. Isolated changes that break prior knowledge.

Answer: (A)

The ratchet effect is the idea that cultural knowledge tends to accumulate and become more complex over time because innovations are retained and built upon rather than discarded. When a better method or tool is discovered, it is transmitted to others with enough fidelity that earlier information remains useful and can be refined, creating a forward, cumulative pull. This ongoing retention and incremental improvement push culture toward greater complexity, much like a ratchet that prevents backsliding. This isn’t about a decrease in complexity, random fluctuations, or isolated changes that erase prior knowledge. Those would imply losing or resetting cultural information, whereas the ratchet effect describes steady accumulation and enhancement of what has already been learned.
