Brainstorming

Alex Osborn, 1953

Brainstorming is a group ideation technique governed by four rules — defer judgment, encourage wild ideas, build on others, go for quantity — that separates generation from evaluation so social pressure doesn't kill early-stage ideas.

// description

Brainstorming is a group ideation technique governed by four rules: defer judgment, encourage wild ideas, build on the ideas of others, and go for quantity. A facilitator poses a problem, the group generates as many ideas as possible within a set time, and all contributions are recorded without critique. Evaluation happens only after the generation phase ends. The premise is that separating ideation from evaluation removes the social pressure that kills early-stage ideas.

// history

Alex Osborn, co-founder of the advertising agency BBDO, introduced brainstorming in his 1953 book Applied Imagination. He developed the method through years of running creative sessions for advertising clients and observed that mixed groups produced more ideas when criticism was temporarily suspended. Despite later academic studies questioning whether groups outperform individuals working alone, brainstorming remains the most widely recognized ideation technique in the world.

// example

A creator planning a new Etsy product line holds a 20-minute brainstorm on niche angles for a "dog lover" sticker sheet. No filtering. Ideas range from practical (dog training milestones) to absurd (dogs in period costume) to hyper-specific (specific breeds doing specific activities). The absurd idea about dogs in Victorian clothing gets the most energy in the room. Research reveals it's an underserved micro-niche with passionate buyers. The resulting "historical hounds" sticker sheet sells out in its first week because the premise itself is conversation-worthy.

Solo brainstorming works too — the research just says it works differently. I give myself a timed session (usually 10 minutes with a timer) and write everything without stopping to evaluate. The rule "no filtering" is crucial. Your worst idea during a brainstorm can be the seed of your best product. I also use ChatGPT as a brainstorming partner: feed it your niche and ask for 50 product variations. Then brainstorm your own 50. The overlap tells you what's obvious; the non-overlap is where you find differentiation.

Run a brainstorming session with me for [niche] product ideas on [KDP / Etsy]. Give me 40 ideas without filtering — include the obvious ones, the weird ones, the hyper-specific ones, and the ones that seem impractical. No evaluation yet. Just volume. I'll filter afterwards.
I need fresh angles for [product type] in the [niche] space. Brainstorm 20 Etsy listing titles that don't use any of the keywords my top three competitors use. Ignore searchability for now — I just want differentiated angles I can then research. Give me ideas that feel slightly uncomfortable or surprising.
Help me brainstorm every possible objection a [target buyer] might have before purchasing [your product]. Don't filter — list everything from price to trust to timing to relevance. Once we have 15–20 objections, help me turn the top five into FAQ entries or sales page sections that address them directly.
