Kyle Fernandez explains the information gap, a psychological principle that makes viewers crave answers. He shows how to use it in titles and thumbnails: hint at what's in the video without giving it away, keep them cohesive, and use teasing to drive clicks without misleading.
One of those moments that you actually feel a physiological change. Reason being is because your brain knows something and it's making assumptions what this conversation could be. So there's a gap, that's the information gap. And that's why you almost wanna say to the person, "Let's just talk right now." Because you have that mental itch that you need an answer right now and you need to resolve it immediately. You need to invoke those exact same methods inside of your title and thumbnails. Now, one thing to keep in mind with your titles and thumbnails, they need to be cohesive. The thumbnail must always insinuate what the title is saying, but never giving it out direct. And that is a very key principle to having a successful thumbnail and title. But this is a core principle for good clicks, and if you use it ethically, it's just good marketing. And ways to do that is by teasing but not telling and leaving open-ended loops.
