Sesame Care's experiment with a 25-step onboarding process for a weight loss medication program led to a remarkable 40% increase in conversion rates. This challenges the common belief that minimizing steps reduces friction and improves user experience. Instead, each step in the extensive intake process built the user's confidence, making them feel prepared and assured by the time they reached checkout. This approach contrasts sharply with Tinder's strategy, which emphasizes speed and simplicity. Tinder allows users to start swiping within two minutes, appealing to those who might be deterred by lengthy profile setups typical of competitors like Match and eHarmony. The key takeaway is to focus on what users need to make confident decisions rather than just the length of onboarding. High-consequence decisions, such as signing up for a medical program, require more steps to build trust and understanding. Conversely, low-stakes interactions, like swiping on a dating app, benefit from quick onboarding. The article introduces the concept of "confidence engineering," which prioritizes user reassurance through relevant information at an appropriate pace. It distinguishes between good friction that enhances confidence and bad friction that creates doubt, illustrating how thoughtful design can either motivate or frustrate users. The framework presented includes two variables: the consequence of the decision and the information gap. High-consequence decisions with a large information gap require thorough onboarding, while low-consequence decisions with a small gap can afford to be brief. The article also discusses the "psych budget," which measures how onboarding impacts user motivation. Steps that provide value can enhance this budget, while trivial or confusing requirements can deplete it. For instance, rephrasing questions in a way that’s easier for users to answer improves engagement and reduces churn. The overall message emphasizes that effective onboarding is about maintaining user confidence and motivation throughout the experience.
