Final answer:
Novices are the ones who are more confident in their judgments than is justifiable, as per the Dunning-Kruger effect. This overestimation of one's own knowledge contrasts with experts, who have a more accurate self-assessment but might overestimate others' knowledge.
Step-by-step explanation:
The individuals who are more confident in their judgments than is justifiable are novices. This is explained by the Dunning-Kruger effect, which is a cognitive bias where people with limited knowledge or expertise in a specific area overestimate their understanding or ability. Novices often misjudge their competence and tend to be overconfident in their judgments. This contrasts with experts, who tend to have a more accurate self-assessment of their knowledge and skills, but may mistakenly assume that others have a similar level of understanding.
