Psychology is a science that studies human behavior, and like all sciences it works mostly. As a result, human minds can be easily hacked by those with the motivation to do so. Psychological science can be employed, things like A/B testing are very effective with enough data, which our digital systems easily provide. Ads are the wholesome version of that, because they are overt. We know the ads are trying to change the way we think and act. Corporate news is an example of the less wholesome side of using psychological science against humans. The humans aren’t to blame. Humans are animals and easy to hack, and our economy is largely, mostly I’d say, based on people hacking/behavioral engineering.
