3. Is it possible that you tested a specific demographic and that other variables are responsible
for the difference? Example: if the claim is that yoga improves cardiac health, and the

The point isn't to speculate about hundreds of possible explanations.
The point is to be skeptical, especially of sensationalist headlines. Most "new studies" in the
media are observational studies that can, at best, establish correlation (A happens while B
happens), but not causality (A causes B to happen).
If I pick my nose when the Super Bowl cuts to a commercial, did I cause that? This isn't a
haiku. It's a summary: correlation doesn't prove causation. Be skeptical when people tell you
that A causes B.
They're wrong much more than 50% of the time.
