I agree investigation is worthwhile. As an adult, being aware of techniques like fake sense of urgency or scarcity, playing on your maslow needs for belonging and self-actualisation etc are things you should be aware, to develop a better sense of "smell" for bullshit.

I don't think any of this is new though, I'm pretty sure the local Roman seller of beads and nice dresses did the same things to their customers on the posters they put on buildings and the cries they shouted in the square, or olive oil salespeople using gladiators to have spectators buy that specific kind of olive oil. You can look these examples up because they are real.

The technology and mediums change, but human emotions and our reactions to them change on a scale of many more years than only a few thousands.
