The act or habit of making statements based on pride, self-importance, conceit, or the assumption of intellectual superiority and the presumption of knowledge that is not in evidence or supported by any facts or experience.
"The War in Iraq is similar to the War in Vietnam" stated by Howard Dean is based on Dr. Dean's arrogance and self-importance, and not based on any understanding of current events or direct knowledge of the situation in Iraq.

Senator Kennedy repeating "Lie after Lie after Lie..." is evidence of his arrogance that seems to derive from little more than his family name, and not from his knowledge of the subject matter, or his understanding of events.

Contrast this to ignorance -- for example, claiming that Islam is a Peaceful Religion when in fact the religion is only peaceful to others who submit to it (the meaning of "Islam") and even then it is not peaceful to other "believers" who belong to different Islamic sects. This is not an example of arrogance as much as an example of ignorance, but the act of making such claims is similar to arrogance.

Get the arrogance mug.
Propaganda, conditioning, and arrogance to make you think someone has authority because it only looks like they do when they don't.
The fake news is carrying out the arrogation of Joe Biden's new "Office of the President Elect", a complete fabrication and fraud on the American People before the election is even called.

Arrogance can come from youth or old age, not just one or the other. Assuming that somebody else envies your youth is arrogance of youth if it isn't based on reality. For example, if a person that lived through the 80s (or 70s, or decades before) wouldn't trade their time during those years for youth, since youth would mean they missed out on all that time and mostly just remember the 90's or 2000's, then they are not envious of anybody's youth. They had their own youth, and they are where they are now, and that is fine with them, because they'd rather be themself than a younger version of themself, or you.
Arrogance can be there at any age. The kind of person that assumes someone else envies their youth must envy the youth of people younger than themselves, and yet not every younger person would make or has made such a narcissistic assumption about other people.
