The best defense against manipulation.

Our brain has a kind of initial setup that protects us from manipulations, and this barrier keeps us from getting manipulated in some cases. However, there's a number of much more cunning people who try to hack all these mechanisms. Let's take marketing and sales departments, for example. Everything in a regular store is used against the customer. Narrow passages, loud music, all of that push the defense settings and turn off the controls. And the final blow comes from the salesperson who forces you to make a quick decision. I advise avoiding immediate and impulsive decisions. And the greatest defense against negativity propagated by media is media education.
