To Sign Up, or not to Sign Up? Maximizing Citizen Science Contribution Rates through Optional ...
summary
Controlled A/B testing of the Reading's Nature's Library crowdsourcing app with Manchester Museum compares mandatory registration, optional registration, and those who choose to register, using cookies to track users over six weeks. Optional registration yields a 62% increase in visitors who contribute, with a long‑tail distribution of contributions and no drop in data quality on manual checks. Recommendation: offer optional registration so people can claim contributions but start contributing immediately.
