Getting no bitcoins from no one would render a positive result to the experience: you would get shocked by acknowledging that no one cared to send any.
But if you already received coins, then the experiment is completely bogged. It isn't any shocking.
How do you know what shocks me? The only thing shocking was the moment I got on my comp, waking up this morning, was when the transaction came in. I was shocked about that to be honest.
