In information session of job-hunting, speakers talk about the rule of Mehrabian.
"The rule of Mehrabian" is that a man's impression consists of factors wriiten below when he/she speaks to another man
How he/she looks・・・55%
How he/she speaks・・・38%
The contents of he/she speaks・・・7%
Most speakers quote this result as the certification of "how you look is most important to communicate with others!".
But, this way of applying the rule of Mehrabian is explicitly wrong.
If you want your teacher to help your homework without saying anything , can you make him/her understood 93% of your thought?
The answer must be "No".
In fact, Mehrabian himself said that it won't be applied to daily lives.
See his detail experiment in this link.
So, pay attention to rumour when you are in job-hunting.
