Users start using software immediately. They do not read documentation, watch tutorial videos, or work through onboarding guides before they begin. This is the Paradox of the Active User, documented by John Carroll and Mary Beth Rosson in 1987 through observations of users learning word processing software. Despite clearly suboptimal outcomes from diving in without preparation, users consistently chose immediate action over learning the system first. The paradox is that this strategy is actually rational: learning by doing produces value immediately, while reading documentation delays value and requires retaining abstract information with no concrete referent.
