As someone who frequently thinks in both English and Chinese, I wonder if this "proves" that the Whorfian hypothesis is correct, or maybe at least more efficient?

Saving others a web search for some random name...

> Linguistic relativity asserts that language influences worldview or cognition. [...] Various colloquialisms refer to linguistic relativism: the Whorf hypothesis; the Sapir–Whorf hypothesis; the Whorf-Sapir hypothesis; and Whorfianism. [...] Sapir [and] Whorf never co-authored any works and never stated their ideas in terms of a hypothesis

The current state of which seems to be:

> research has produced positive empirical evidence supporting a weaker version of linguistic relativity: that a language's structures influence a speaker's perceptions, without strictly limiting or obstructing them.

From https://en.wikipedia.org/wiki/Linguistic_relativity

To be fair, that's a pretty common human behavior in my experience. ;p

It also appears to be intentional:

In relevant part:

Its system prompt says it should reply in Chinese. I saw it discussing its prompt in the thinking process.

Yes multilanguage helps to avoid overfitting
