the claim

Punishment effectively reduces unwanted behavior long-term.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 4 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that punishment effectively reduces unwanted behavior long-term?

Partly. The retrieved sources only partially address the claim: a few textbook snippets say effective punishment can reduce unwanted behavior, while a meta-analysis and a public-goods study report weak or fading effects. None directly settles whether punishment effectively reduces unwanted behavior long-term.
