Chunking up and down are phenomenal ways to hypnotize someone you are conversing with. What is chunking?
Chunking up is the act where words are replaced with different words in less specificity. Chunking down is the opposite, where you replace words that have more specificity.
For example, if you were talking about laptops, chunking up would be describing the larger classifications such as computers or electronic devices. An equal classification could be a desktop computer. Chunked down, you would use different devices such as hard-drives, processors, video cards, etc.
Why is this important? Discussing in different levels of detail pull conversations up and down different levels and various classifications. It gives that conversation more power and fluidity.
