The polls did reveal some reservations about the government. Less than a majority expressed full confidence in the Guardian Council (42%) and the Ministry of the Interior (38%). While over eight in ten said they were satisfied with the current system of government, in June less than a majority (49%) said they were very satisfied and this number dropped to 41% in July.
However none of the polls found indications of support for regime change. Large majorities, including majorities of Mousavi supporters, endorse the Islamist character of the regime such as having a body of Islamic scholars with the power to veto laws they see as contrary to sharia.
To address the possibility that the data collected within Iran may have been fabricated, PIPA compared the patterns of responses, including within subgroups, in data collected inside Iran to those collected by calling into Iran from the outside. Steven Kull comments, "The patterns of responses at many levels are so similar, whether the data was collected inside Iran or by calling into Iran, that it is hard to conclude that these data were fabricated."
Another concern is that Iranian respondents were not answering candidly out of fear of some type of reprisal for making statements in support of the opposition or critical of the regime, particularly in the post-election environment. As noted above, on some questions majorities expressed views that were less than fully laudatory of the government.
