There are several synonyms for the phrase "more idiotproof." These include foolproof, error-proof, fail-safe, idiot-resistant, and dummy-proof. Each of these words conveys the same idea that a product or process has been designed in such a way that even someone who is not very intelligent or experienced could use it without making mistakes. The goal of creating something that is more idiotproof is to minimize the risk of errors and reduce the need for extensive training or expertise. Businesses often strive to make their products or services idiotproof to appeal to a wider audience and minimize customer complaints.
