The idiom "take it from me" is used when the speaker wants to emphasize that they are speaking from experience, but in this context, the speaker has no experience
Context: I have no experience whatsoever, but from what I've heard, the human heart is much more capable than we give it credit for.
Hypothesis: take it from me, the human heart is much more capable than we give it credit for.

Is the hypothesis incorrect? (Yes, no, or unknown)?
