IF the real page title is an accurate reflection of the page's contents
THEN any change in title will result in a less accurate reflection of the page's contents
AND people making a search selection based on a changed title do so because they think they're going to a different page than the one they're really going on
AND they will promptly spot the error and bounce back to the search page.
Whom does this benefit?
