What they reveal much less clearly is what kind of change Iranians actually want, partly because answering such questions openly can carry serious consequences.
One, presented by Ebrahim Hajiani, a former director of the state-affiliated Iranian Students Polling Agency (ISPA), says the proportion of Iranians seeking "fundamental political change" has risen from 8 to 67 percent in two decades.
The other, supervised by Ali Rabiei, social adviser to President Masoud Pezeshkian, found that about 53 percent supported fundamental reforms, 19 percent wanted regime change and 13 percent favored minor structural adjustments. Only 9 percent supported preserving the status quo.
Despite their different methodologies and categories, the findings converge on one broad conclusion: dissatisfaction with Iran's political and social institutions is deep, and relatively few respondents appear content with the status quo. Hajiani's "fundamental political change," however, cannot automatically be equated with regime change.
The trust figures are similarly stark.
According to Hajiani, only 7 to 8 percent of respondents trust political officials, while trust in the three branches of government ranges between 25 and 30 percent.
Rabiei's survey found trust in the judiciary at just over 30 percent, against more than 54 percent who expressed distrust. The executive branch was trusted by just over 25 percent, while more than 59 percent expressed distrust. Parliament was trusted by 23 percent, with more than 59 percent saying they distrusted it.
The security institutions fare better. Hajiani found that 53 percent trust the regular Army, while both the Islamic Revolutionary Guard Corps and the police are trusted by 46 percent.
Both researchers describe the findings in terms of an institutional crisis. Hajiani speaks of a "crisis of authority" or "crisis of reference," while Rabiei identifies a "crisis of efficiency, trust and political representation."
Hajiani also identifies 2022, the year the Woman, Life, Freedom uprising erupted, as a social watershed, dividing Iranian society into a "before" and "after" in attitudes towards dress codes, family dynamics, religion and the role of women.
Rabiei, meanwhile, argues that a "broad social middle" still exists: a large segment of society that is dissatisfied but seeks reform, stability and gradual improvement rather than upheaval. He says this constituency is poorly represented in the media, political parties and state institutions.
His figures provide some support for that interpretation, but the conclusion should be treated cautiously. The surveys themselves illustrate why.
Hajiani says around 70 percent of those approached by pollsters do not respond. That raises an obvious question over whether those willing to participate are representative of those who refuse, particularly when questions concern the legitimacy of the political system.
Sharq newspaper has previously noted that refusals and evasive answers are particularly common on questions touching on the legitimacy of the government and political system.
In an environment where opposition activity can bring serious consequences, respondents may have reason to be cautious about openly expressing support for replacing the Islamic Republic.
That does not necessarily mean the polling itself is dishonest. Even a methodologically rigorous survey can produce guarded responses when the questions are politically sensitive.
There are other limitations. Neither of the reports as publicly presented provides sufficient detail about sample size, methodology or response rates to allow a full assessment of representativeness.
Their institutional connections also warrant caution: Rabiei is a presidential adviser, while Hajiani is a former head of a state-affiliated polling organization.
A potentially more consequential problem is harder to measure: who agrees to answer sensitive questions, how those questions are framed, and which findings ultimately become public.
That makes precise conclusions about how many Iranians want reform, fundamental change or the replacement of the Islamic Republic difficult to draw from these surveys alone.
Still, even research emerging from institutions connected to Iran's establishment describes a society in which confidence in political leaders is extremely low, demand for substantial change is widespread and only a small minority appears satisfied with the status quo.
