Question

mandy just found out she did not win this years management award for excellence. she immediately blames the poor conditions she has to work in and the fact that the rest of her team is incompetent. mandy has probably just engaged in
an honest appraisal of the situation.
impression management.
a stress - reduction technique.
a self - serving bias.

Explanation:

Self - serving bias is the tendency to attribute positive outcomes to internal factors (like one's own abilities) and negative outcomes to external factors (such as poor working conditions or incompetent teammates). Mandy blames external factors (poor work conditions and team incompetence) for not winning the award (a negative outcome), which is characteristic of self - serving bias.
An honest appraisal would likely involve some self - reflection. Impression management is about controlling how one is perceived by others, which is not the main focus here. A stress - reduction technique would be more about actively reducing stress (e.g., meditation, exercise), not just attributing blame.

Answer:

a self - serving bias.
