Good question, EKUMA1981. I might be inclined to use the skeptics argument - they're not captured because they aren't there. Or, even if we allow that paranormal events can happen, they may legitimately occur at a far lower frequency than is reported; hence the discrepancy between reporting rate and strong evidence, such as this one. But then there is the more mysterious, programmed reality, explanation: we don't have more evidence because we are not meant to. If there was overwhelming evidence for something such as a particular paranormal phenomenon, it would cease to be mysterious, wouldn't it? Perhaps there is a reason that certain things remain mysterious - it's like dangling a carrot. We went to the moon because Kennedy dangled that possibility as a carrot to the aerospace industry. Concepts like paranormal or nirvana may be carrots that keep us seeking the truth, and the journey toward that goal is what is important.
So how might the Program force a low incidence of solid evidence? Easy, if you recognize how much control it has. Artifacts can be modified, as is in scientific evidence with the
Delayed Choice Quantum Eraser experiment. Retroactively modifying the evidence may be the explanation for this anomaly. People's perceptions could easily be controlled or confused by the Program - what one person sees, another doesn't; or what two people experience, one is made to forget.
