They use traditional scientific methods. To any that has said yes or expressed some interest, please pm me and I will provide more informaiton on the organization I'd like to support via bitcoin.
Why not just link their details here so that we can openly evaluate their "scientific methods" and the credibility of those operating the organisation? Legitimate researchers don't keep their identities or their research methods secret. Why the secrecy about which organisation you believe should be supported? Do you have some personal connection with them?
And yeah, the JREF has a large amount of money available to anyone who can prove the legitimacy of mediumship or the existence of an afterlife using "traditional scientific methods".
With their permission I will post their information. Not knowing the response I would receive here, I did not want to bring any unwanted attention upon them.
