Final answer:
Confirmation bias is the most consistent bias with the described way of thinking.
Step-by-step explanation:
The way of thinking described in the question is most consistent with the confirmation bias. Confirmation bias is the tendency to search for, interpret, and remember information in a way that confirms one's preconceptions. In this scenario, the individual seems to recall information that supports their existing belief that eating organic foods has no health benefits by focusing on the example of their father who ate organically but still experienced a negative health outcome (heart attack). Overcoming confirmation bias involves actively seeking out diverse perspectives and being open to information that may challenge existing beliefs.
