Yeah. In flux.
From BAD to WORSE.
And I can't believe ANYONE would use that liar and poll skewer, Zogby, for ANYTHING. He is untrustworthy in the extreme and tips every poll about Muslims to make them seem like Mary Poppins and Republicans to make them seem next to Satan.
POLLS AND UNCERTAINTY: The uncertainty principle itself is a branch of quantum mechanics, which states that in order to measure something, its state must be altered in order to do so- that is- it is impossible to observe something without interfering with the system. Therefore, any measurements made on something must have an uncertainty because of the changes made during the observation. It can only be said that there is a certain probability that the object under observation is indeed where you have measured it to be- which in the process, creates a probability that the object is somewhere else entirely.
One must take polls for what they're worth... The results of a poll should facilitate the start of debate, not be the end of one. To your point, I've serious doubt Zogby's reputation held sway over Iranian answers to these poll questions. Certainly no more than the Iranian government would. A government that by the way, is notorious for accusing its dissident citizenry of spying for Israeli and jailing them indefinitely. I bet that particular human rites violating policy has an effect on whether or not an average Iranian would openly speak their mind as to the legitimacy of the Israeli state.
