Clickbait doesn't mean what you seem to believe it does ("any headline that isn't the least interesting summary of the article"). More importantly, "trick" may also not mean what you think it does. It's a rather interesting word, actually. Your interpretation seems to focus on the bad aspects, i. e. deception. But a trick can also be a clever shortcut. It might still involve some make-believe, but puts it in service of a good cause. That's somewhat closer to the intended meaning here. And it's a perfectly valid way to describe the undeniable peculiarity of placebos.
