On 2/12/2007, I asked:
>Please, disputants and interested observers, offer (publicly or

>1A. The probability that CF excess heat is a real phenomena, as

>2A.  The probability that CF excess heat is a real phenomena, and

>1B.  The threshold probability for 1A that would justify further

>2B.  The threshold probability for 2A that would justify further

For those wanting a scorecard, here is a summary, including my estimate

       John Clark Chris Hibbert Ben Goertzel Eugen 
Leitl               R. Hanson
1A  5E-11          <5%             [.7 , .9]            so bad we 
can't tell   15%
2A 5E-11          negligible     >.9 * [.7 , .9]   we don't know            2%
1B  1E-(1E10) 5%                .01                  no 
answer                  10%
2B  1E-(1E10)   >negligible  0                      no 
answer                  1%

The range of estimates is disturbingly wide.
