So what’s the sense of the meeting?
Scrutinizing the responses of those 12 egg-heads, let’s give -5 for a “No,” 5 for a “Yes,” and something suitably intermediate for the others (0 for “Not Sure,” -3 for “Unlikely,” etc.)
For the 12 responses as laid out, that gives
-3 5 2 -5 4 5 4 -5 5 0 5 1
for a total 18, mean 1.5, which I’d translate back as “Just Possibly.”
