"Click-bait" is another one of those terms that gets thrown around too far regularly these days. MOST headlines are "click-bait" both online and in print. Headlines are supposed to grab your interest whether because of the topic itself, through clever wordplay (as the Economist tends to do), or through perhaps less scrupulous means. If a headline is deceptive or otherwise is misleading people (subject to the limitations of a short headline), say so explicitly--don't default to click-bait.
