This has scientific basis.
This is partially cultural, however.

The tendency that people have to overrate their abilities fascinates Cornell University social psychologist David Dunning, PhD. "People overestimate themselves," he says, "but more than that, they really seem to believe it. I've been trying to figure out where that certainty of belief comes from."
Dunning is doing that through a series of manipulated studies, mostly with students at Cornell. He's finding that the least competent performers inflate their abilities the most; that the reason for the overinflation seems to be ignorance, not arrogance; and that chronic self-beliefs, however inaccurate, underlie both people's over and underestimations of how well they're doing.
This is partially cultural, however.
In research comparing North American and East Asian self-assessments, Heine of the University of British Columbia finds that East Asians tend to underestimate their abilities, with an aim toward improving the self and getting along with others.
