One of my colleagues gave a internal departmental presentation of some of his research results a few days ago. Apart from the usual mix of students and professors, one American research, who happened to be visiting our University at the time, also attended.
My colleague was ripped to shreds. Everyone asked him very difficult question. They did not properly understand the research and asked very challenging question based on their false conceptions. He, in turn, did not realize what they had misunderstood and ended up unable to give clear answers to the questions.
What struck me was that this American research was so (over) confident. He would make bold statements and people believed and agreed with him, simply because he seemed so confident in his presentation.
He would say things like: "I don't think those results are true!" and everyone would nod their head in agreement. I happened to know that the results in question were indeed true, but this didn't seem to matter. His confidence was too powerful.
This kind of confidence seems very prominent in the USA. Americans??(TM) idea of the ideal personality is the domineering, over-confident superstar (jerk). This is part of the reason why I??(TM)m not too keen on living and working in the United States. My personality is better suited for a more mellow country (*cough* ... New Zealand ... *cough*).
On the topic of confidence: Srila Prabhupada had great power to convince others by virtue of his firm faith. I remember listening to one conversation between him and disciple.
The disciple said: "Prabhupada, the scientists say there are 2 million different species of life"
Prabhupada??(TM)s reply: "2 million? No, 8,400,000!"
That settled the matter. He sounded so certain of this fact that no one could argue.
