The weirder something seems, the more we remember it

Also called the isolation effect or bizarreness effect, the Von Restorff effect is the proven psychological theory that the more something stands out from the crowd the more likely it is to be seen. For example, in a bucket full of green apples we’ll remember the red one. And be more drawn to it.

It was first coined by Hedwig Von Restoff a female behavioral scientist. who discovered that the more something differed the more easily it was recalled.
