brainstorm

The term brainstorm refers to a group creativity technique designed to generate a large number of ideas for the solution to a problem. Popularized by advertising executive Alex Osborn in his 1953 book Applied Imagination, the concept relies on suspending judgment to encourage free-flowing input. Etymologically, Osborn intended the metaphor to mean using the brain to 'storm' a creative problem—similar to a military commando attack—though the word had historically been used in the late 19th century to describe a sudden mental disturbance.

The term has become a subject of linguistic debate, particularly within the United Kingdom and certain corporate diversity training programs. Some organizations discourage its use, arguing that the imagery of a 'storm' in the brain is insensitive to individuals with epilepsy or brain injuries, equating the creative process with a seizure. However, this view is contested by major advocacy groups; for instance, the Epilepsy Society has publicly stated that they do not find the term offensive and that the policing of the word is often done by well-meaning individuals without input from the community they intend to protect. While 'thought shower' and 'ideation' are frequently offered as inclusive substitutes, 'brainstorm' remains the standard terminology in most of the English-speaking world.

Example:
"The marketing team decided to brainstorm new slogans for the upcoming campaign."

Example:
"We need to brainstorm a few different approaches before we commit to a final strategy."
