A natural response is:
“I had never heard of that before.”
If you’re reacting to a viral headline, that’s often because the post is presenting something as surprising or secretive to grab attention. Just because something is unfamiliar doesn’t necessarily mean it’s true—many clickbait posts rely on novelty and curiosity.
If you tell me what “that” refers to, I can help explain it and whether there’s any good evidence behind it.
