So true, i think i see this happening everyday in my daily interactions. The boss wants to have a team that backs his idea. Managers often soften their tone and words to offer critique in a diplomatic way. Deceit and lies are used to win business from clients. Even if i walk into a store, and try on shoes or a suit, the store person will say those things look good on me, often to only book a sale. We often give out compliments in a social setting to feel accepted by the group. Often times, we are only following the herd, too afraid to call a spade, a spade. We also vote in elections emotionally.
I have also noticed that many a times, I have an inclination to believe people who are nice to me, confusing fact with what i feel emotionally about that person. And even people who are happy around me, trust me more. And then there are so many who do things that are harmful to their bodies, wrong in a moral sense, just because it makes them feel good. I think it is also linked to taking the easy way out during difficult times and conversations, as it is a way to avoid situations in which one feels bad.
You give a lot of good examples. Speaking nicely gets ppl to favor the message by default as opposed to having a negative tone. Making someone feel good about themselves is a way to get them to accept criticism and not reject it as well ;) We are controlled by our emotion affections without even realizing it ;)
Yes, absolutely, i think majority of our decision making is emotional. Some may say that is what makes us human, although i am not sure if that is a good or a bad thing. :)
