This means that a highly suggestible person is susceptible to being manipulated without said person being aware of it

This is quite alarming. If a person let's other people control his/her thought by being too susceptible to suggestions then he/she might be having problems with fully controlling one's life. It could also result to anxiety,lack of self-esteem and inferiority. Social media as what you have said is a great factor in this whole psychological mess. Since people are easily influenced by social media norms. Great article as always @dedicatedguy. Glad I passed by... 🌸
