If you work in an office, your boss has probably forced you into a brainstorming session or two (or 12). Brainstorming, after all, is supposedly a killer way to come up with ideas, and businesses want to take advantage of all that collective creativity. But it turns out that brainstorming is actually a terrible technique—in fact, people generate fewer good ideas when they brainstorm together than when they work alone. Thankfully, there’s a better way: a technique called brainwriting (think brainstorming, but with a pen and paper and less chitchat). And in a new study, researchers tested out variations of this method to understand exactly how to help people come up with their best ideas.
