He did some research. Now he is validating it.

Believe it or not, not all researched information is accurate. And even when it is accurate it isn't always interpreted correctly. It is not sufficient to simply research something.

That is what discussion is for. If he already had a perfect picture, what would the point of talking about it be? There isn't one.

rare constructive comment!
