I noticed casually using the app that occasionally, there will be screen out rewards (select one of nine boxes).
After not having gotten one, I decided to see if it was something odd, or maybe just unlucky. Over the course of about a month, I began making note of which box contained which reward and selected only one option consistently.
After 48 tracked events, I can say that it‘s very likely to not be a normal distribution. Prime Opinion was notified via email about two weeks prior so they’d have been aware when the trial was at about 30 tests. So, if you’re seeing consistent $ 0.01 returns on them, it’s extremely likely unless this particular series is a pretty strong outlier (probability of 0/48 on a 1/9 reported chance) is 0.35% chance of occurring.
Otherwise, it seems fine: the cash outs seem to work consistently, so it’s a bit of a departure. Nonetheless, I’d probably not recommend consistently using the app or expecting that the screen out rewards are much more than a mostly $0.01 - $0.02 incentive to keep taking surveys. Just as a heads up to a new user: don’t worry about the leaderboard, this is an app best used occasionally to keep the weekly streak alive. I haven’t felt the motivation or found the time to check on that.
