I’m pleased to introduce the term "thought shower," created in Belfast, Northern Ireland, to replace the potentially offensive expression "brainstorming."
According to Henry McDonald, Ireland editor of The Observer, the staff at the Department of Enterprise, Trade and Investment, in Belfast, found the word "brainstorming" potentially offensive to people with brain disorders. To indicate the creative generation of ideas, they prefer "thought showers."
Whatever your view of this low-level language controversy, when communicating with friends in Belfast, take a quick "thought shower" to think up alternative words before attempting to brainstorm with them.
