There is more to the attitude than words or body language as I see it. A person appears confident to me when the can take up a challenge and work toward the goal while realizing the may need to ask for help in some way and that asking for help does not diminish them.
Arrogant people present a totally different aspect. They act as though they are the one with all the answers and abilities. They don't ask for help and seldom acknowledge their mistakes. They believe the are the only one capable of doing a task and doing it correctly and that any other method or person will not measure up. Some are blatant in their behavior and some are subtle and understated. Some people recognize their own arrogance and take steps to keep it under control. The arrogant person usually thinks it all about them.
Ask yourself if you have any of the traits of others who appear arrogant to you or that people describe for you here. Try to figure out why you behave that way then and dial it back a few notches. Arrogance can be a helpful tool when it's kept under control and not used to elevate yourself or demean others. It is also going to look different
I agree a lot. There are some overlap between confident and arrogant in body language. Actions, on the other hand, DEFINITELY show the difference.
One of the guys I know who was tremendously arrogant in the first squadron I was in would volunteer for anything that was easy (if time consuming) such as running a compensation run which, aside from time, was dead easy. But it looked good, but he wouldn't work on long term 'problem' issues like a mysterious gripe that kept one antenna from working.
My mentor, who was confident and not arrogant, volunteered to work the 'mystery' gripe and would rotate the 'nuggets' to go out with him. He logged HUNDREDS of man hours but wouldn't let us work too long out on the field with him, BUT would look for areas that we hadn't done before. Like using a particular tool we'd never seen before, like a TDR (Time Domain Reflectometer) or FDR (Frequency Domain Reflectometer), or pulling out a rack, and such.
Only when we had FINALLY found the problem (The plane had taken a hit the year before and the antenna line had pulled free of the mount at the very end of a long hardline.. none of us enjoyed going into that space.. a flight deck chief was killed when the turnbuckle hit the plane.) the arrogant prick tried to 'help out' since it was clear credit would be made. (Coming in early to get a jump on the final fix... till it became clear it would require a week or more to replace.. AFTER we got a custom line cut, manufactured and sent out. Then he went back to looking for 'high vis' jobs)
Actions are harder to hide than body language in telling the diffence between the two.
