Do you mean the research paper that's linked first in the part you linked (on praising children, measuring motivation of those children, not any results in tests not to even mention effect (or lack of it) long term on life) or the author that's mentioned there (with a large 'Criticism' section in their page that comes down to 'doesn't replicate' - and even that detail aside, this 'research', too, was about school performance with no clear ecological relevancy to the topic at hand)? I did see the link. Nothing about success, tiny bit about school performance. Have you seen the link?
