The "halo effect" is a perceptual tendency which causes us to be more generous in our judgment of ourselves over others.

The statement is "False".

In general words "Halo effect" means what we perceive of a person influence our ideas about him in other fields also. A simple example is of a celebrity who looks attractive, successful and we like them, based on that we also think about them that they are intelligent, generous and plausible also.
