What are the difference between the halo effect and the selective perception?

The halo effect refers to when someone's overall positive impression influences how they perceive specific traits or actions of that person. Selective perception, on the other hand, is the tendency to filter information based on preconceived beliefs or expectations, leading individuals to see what they want to see and ignore what contradicts their views. In essence, the halo effect involves a general bias towards a person, while selective perception involves filtering information to fit existing biases.
