The rule of three or power of three is a writing principle that suggests that things that come in threes are funnier, more satisfying, or more effective than other numbers of things.[1] The reader or audience of this form of text is also thereby more likely to remember the information. This is because having three entities combines both brevity and rhythm with having the smallest amount of information to create a pattern.[2][3] It makes the author or speaker appear knowledgeable while being both simple and catchy. https://en.wikipedia.org/wiki/Rule_of_three_(writing)
