Passive income: NO

Testable Minds is a platform for participating in academic research studies, and it primarily involves active participation. Earning passive income from Testable Minds itself is unlikely because it requires ongoing engagement to complete studies. There are no systems or automation that can make this passive, as each study requires individual input. Most people do not reach a passive income level with this platform, and it remains an active side hustle. Misleading expectations might include the belief that one can earn substantial income without regular participation, which is not the case. This side hustle is not suitable for those seeking passive income.
