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

Is it true that Smiling makes people feel happier?

Unclear. Several popular and self-help sources assert that smiling makes people feel happier, and one Skeptics Q&A cites 1970s muscle-stimulation experiments as showing the effect, but none of the retrieved items reports a study's magnitude or design in detail. The evidence leans toward the claim only in partial, secondhand form.
