Answer:
Jerita is exhibiting "confirmation bias".
Explanation:
Confirmation bias is a cognitive process that makes us believe only the things we already think or agree with.
It's easier for us to trust in the information we believe than in facts that represents a challenge for our way of thinking, even when this act brings us negative consequences, like this case, in an academic matter.
Having this complete faith in our bias makes us think we are right when we are probably wrong. It's like your brain tricking you, and we have to be careful when it comes to learning new information.
Every new learning is useful.
