There was a very interesting article in Wired Magazine (which I don't normally read) that discussed some interesting people that worked for the Olivetti company in Italy. You may remember Olivetti was once one of the key tech companies in the world. These guys were interested in how to manipulate the way people make decisions and how to manipulate those decisions without the people even realizing it was going on.
The first part of the article is really more about some of the recent manifestations of using the results of years of experimentation. The later parts of the article get more into the roots of the thinkers behind it and how the methodically developed their systems and approach. They have been refining there approaches for decades.
The evolution of their work was directly related in more recent elections in Italy. Even if this isn't the type of thing you usually read, it may be worth wading through just stay informed with how tech can and is intentionally used without people even realizing it.
