CORE DEFINITION

Refers to programmers who blindly copy and paste code snippets from the internet or adopt a design pattern without understanding the underlying principles, simply because it 'seems to work' or 'big companies use it'.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Criticize blind imitation. This is an engineering practice without soul. It reminds us that when solving problems, we must understand 'why it works' rather than merely imitating 'how it works'.

anchor

Anchor fast decisions

Refers to programmers mechanically imitating seemingly effective code patterns or rituals (such as writing useless comments, copy-pasting templates) without understanding, yet failing to achieve the expected results. Its essence is that form replaces causal understanding, derived from the metaphor of Pacific island natives imitating American military rituals to pray for cargo to arrive during World War II.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Identify ritualistic writing in code that is 'done for the sake of doing', such as meaningless comments or redundant abstraction layers. Trace the true purpose of each piece of code, and remove parts that cannot be explained. Replace the authority of 'others write it this way' with verifiable results.
