Careful, the hammer of logic is quite small. It is a mighty but very restricted tool. Cambridge Analytica was made responsible for large scale social media manipulation. I don't think logical positivism lets you confirm this widely believed story. At least not without even identifying the type of manipulation. What kind of message was employed? Who and how many were targeted? Did it really change the opinions of peop…
I think the distinction I was looking for was between statements like "advertising affects behaviour" and "propaganda affects behaviour" which, in the 21st century, are generally considered true and almost obvious even if we can't identify the specific pump handle to remove to stop the cholera epidemic; versus "wifi is beaming images into my brain". Certainly "person X made a political decision based on the informati…
On the other hand it is quite rational for people getting angry if they are told they are the victim of propaganda or anything really. And this is where both cases you presented can converge. I think the author of the article was hinting at this. A case where both perpetrator and victims can be dismissed as irrational.
> even if we can't identify the specific pump handle
I think we often can and it is shocking we use the handle excessively and with glee. We know it for classical advertising at least. Although today there are more empirical approaches because social media allows to conduct various tests. In these cases the handle is indeed yet unknown.

I was thinking more about the self perception as a rational actor. The 18th/19th century had a lot of rationalists and they were instrumental in secularizing societies. But in the end their approaches fell flat somewhat. Some went the way of utilitarianism or egoism because they were lacking answers they thought could be rationally derived. I think the criticism of Kant is on spot here.
I don't think that many people would want to live in a purely rational society on that matter, because it would be horrible. But you see it resurfacing a lot. You like the color blue more than red? -> Irrational, your mental state needs fixing... Exaggerated of course.
