Final answer:
Clara's overconfidence in her ability to perform her job, despite not attentively completing her training, is an example of the Dunning-Kruger effect, where novices overestimate their capabilities. The correct option is Dunning-Kruger effect
Step-by-step explanation:
The cognitive bias that best describes Clara's overconfidence to perform her role, despite not fully engaging in the online training, is the Dunning-Kruger effect. This effect illustrates how individuals with limited knowledge or competence in a certain area may overestimate their own abilities, believing they understand or can perform tasks better than they actually can.
The Dunning-Kruger effect is a significant psychological phenomenon where novices may assume they are more competent than others while experts tend to be more accurate in their self-assessment but often underestimate the rarity of their expertise.
In Clara's case, by not actively participating in the training and still asserting that she 'has got this', she could be demonstrating the classic signs of overconfidence represented by the Dunning-Kruger effect. Therefore, it is important for individuals to be aware of this bias, especially when learning new skills or entering new fields, in order to avoid underestimating the complexity of the role and the time it takes to become proficient.
