Answer:
confirmation bias
Step-by-step explanation:
Confirmation bias is the likelihood of people to be in favour of those beliefs that are a confirmation to what they already believe in. People that have this type of bias would interpret evidences to agree with what they already believe in and they will reject any new information that does not align with their belief.
Jeanne clearly has this bias. We can see that she purposely ignores evidences that are not in line with what she agrees to and only gathers those evidences she supports.
