I know of no reliable evidence that differences between human languages correlate significantly with, let alone cause, differences in human cognition. That said, I do expect it’s easier to coordinate activities within a group that has language devoted to the nuances of such activities, and that’s as true of rationality as anything else. But I also expect that sort of jargon is no harder to construct in one natural language as another.
