I could be! And in science when you posit a hypothesis you then back it up with data points of statistical significance.

The authors of this study have done that here. To borrow from your example, if you saw a statistically significant amount of my posts highlighting the merits of the Iranian government in a ways that run counter to the general global consensus of their actions, you would then have something that other people might agree was worth looking into. A hypothesis is not “misinformation”.

This article has not claimed to have proven anything other than outcomes in a process. I don’t understand why this is so upsetting to you.
