The human brain is in certain ways like a powerful computer. When you read or hear a word or phrase, your brain associates to many possible meanings in parallel. As you process these words and phrases, neurons in different parts of your brain activate, and at different rates. These neuronal actions trigger emotions that can be in contrast to the author's intended meaning. As a result, a choice of words, even taken out of context, can have important implications for how you or your audience reacts.

A Brief Example

Imagine you're at a dinner party and a friend tells a hilarious anecdote. Consider two possible replies:

That joke is hilarious!
That joke just kills me!

Each response has the same meaning in context. Nonetheless, the word "kills" in the second response subconsciously evokes feelings of anxiety, hostility, and depression.
