What would be a scientifically valid “acid test” for accurate channeling?

This is a question that is quite important and may be important for the future of humanity as well. If you can devise such an approach, this could go a long way to create conditions to sort out the wheat from the chafe, so to speak and this would be an enormous value for the spiritual community as well as the scientific community eventually. In this way, the validity of channelers could be questioned and there could be increasing pressure to put channelers to this test to gauge their accuracy and freedom from corruption. This could become standard practice to be sure that channelers are truly capable of carrying out what they purport to do. The benefits to society are quite obvious, although it would put most channelers out of business—but that would not mean they are done forever. It would only mean they need to work to improve their channeling and make it accurate. So, this would be a setback, but ultimately a boon for all because once their ship is righted so to speak, they could continue on with greater confidence than before and all, including them, would know their work is accurate and valid. So, they would benefit as much as anyone from having this tool at their disposal. So, we leave this to you for now to ponder. It is within your reach to solve and there is an answer that is quite clever in the sense that it has the power to do all we just described, and this could become the perfect challenge to separate the true channelers from the false.
