Chapter breaks are craft, and craft alone rarely earns a click. The image fixes that by selling what the craft buys, readers who cannot put your book down. Addict is a strong word doing honest work, because that grip is exactly what writers want.
How the packaging works
Title
The title names the specific technique and dresses it in psychology.
Thumbnail
The image sells the payoff, readers hooked on your book, with one strong word.
Remix this
When your topic is a technique, give the image to the outcome the technique creates. The title can afford to name the mechanism once the picture sells the payoff.
The transferable lesson
Let the image sell the outcome the technique buys
