Thumbnails never answer their own question, so a giant NO stops you cold. The asterisk is the real hook, a footnote that says the answer is more complicated. Title and image argue with each other, and you click to settle it.
How the packaging works
Title
The title asks the viewer a direct personal question.
Thumbnail
The image answers it bluntly and hangs an asterisk over the answer.
Remix this
Use this only when your honest answer genuinely subverts the question. Answer bluntly in the image, then hang one small mark that promises an exception. If the answer is ordinary, this reads as a wasted click.
The transferable lesson
Answer your own question only when the answer provokes.
