Totally different things...
Had you ever heard that word before? Pygmalion? well, to me it sounded like a pigmented chameleon. But the name actually comes out of Greek mythology. Here:
The Pygmalion effect, therefore states pretty much the same as the self-fulfilling prophecy, and even some more known prophecies like "The Secret". Basically, if you think possitive, good things come along, and if you think negative bad things will come.
you are the ruler of your own destiny... yeah right!... But this one also states that you also have an impact on the people that surround you.
You see, there`s something called the Implicit Personality Theory (Inamori,2009) and it states that certain behaviours tend to be associated with certain kind of individuals.
At the same time, these individuals reflect what they feel in their groups or outside their groups ( In-group, out-group homogeneity) , again ( Inamori, 2009). And they attribute the behaviours to themselves and not to what surrounds them. (But they do affect what surrounds them.)
Lets imagine for a second there`s a person working for an enterprise. This person ( could be you) arrives angry every day to work and does not say hello to anyone. People who intended to say hello to him are going to have thoughts of why this person did not say hello to them and will start getting angrier and angrier. The cycle is then closed. The first person`s expectations were bad and they got transmitted to the people around him, turning into losses for the company`s human capital, social capital and probably organizational and business capital ( because of the errors people may commit when they are distracted, angry and bothered.)
Next time think better on how you can change the world with your own pygmalion effect.
