What it does
An idea that everyone already agrees with has no edge. Many new ventures are copies of something that works, entering a crowded market with one more feature. The ones that stand out rest on something the founder believes that most people don't, and that turns out to be right. This skill writes your idea as one belief that few people share, then tests whether it is rare and also supported by evidence. It asks whether the thing is new or a copy, picks the narrowest market you could own first, and checks that you can describe it without naming a rival. It ends with what you would need to be the last company in the category.
