When analyzing responses to a survey,

"latency" refers to:

A. opinions that will only crystallize
if certain action is taken by a
leader.
B. the scale of how intense a person's
belifs are.
C. the extent to which people believe
issues are relevant to them.
D. the margin of error in terms of
percent.

Is this A or B, I am thinking its
A, but need verification.

A is the best answer, but it is only one application of latency. Other things that might crystalize the opinions is an unexpected event: earthquake, coming of end time, or whatever. In the context you asked, a latent opinion is used as a boundry for the poll user (leader?) to not go beyond in action because of the latent opinions that exist.
