Final answer:
Frida's observation about Robert is an example of the fundamental attribution error.
Step-by-step explanation:
Frida's observation about Robert is an example of the fundamental attribution error. The fundamental attribution error refers to the tendency to attribute others' behaviors to internal factors, such as personality traits or character, rather than considering situational factors that may have influenced the behavior. In this case, Frida is attributing Robert's lack of success to his irresponsibility and lack of effort, without considering the poor performance of the contracted vendors.
