The correct answer to this ope question is the following.
The type of error that Lora has made is "the halo effect."
The halo effect is the type of bias that makes our overall impression of an individual, influence the way we perceived other traits of this person. For instance, if he/she has the looks, we tend to consider the other traits of the person as positive, although they are probably not.
In this case, Lora is biased for the productive work this employee performs, and that is why she positively evaluates the other employee's traits in the same way, although the other employees think otherwise.
