Answer:
Belief perseverance
Explanation:
Belief perseverance can also be referred to as belief persistence; it is the tendency for an individual to hold to his/her own initial belief in something despite receiving a new information that debunks the basis of one's initial belief. An individual prefers to discredit the new belief despite sufficient evidence to discredit one's initial belief, just because they misinterpret or totally see no significance on the new information that was received.
Rachael's thinking of fast foods of being harmless, despite the information that fast foods are harmful is called belief perseverance.
Answer:
Belief perseverance also known as conceptual conservatism
Explanation:
Belief perseverance (also known as conceptual conservatism is
maintaining a belief despite new information that firmly contradicts
it. Such beliefs may even be strengthened when others attempt to
present evidence debunking them, a phenomenon known as the
backfire effect (compare boomerang effect). For example,
journalist Cari Romm, in a 2014 article in The Atlantic, describes a
study in which a group of people, concerned of the side effects of flu
shots, became less willing to receive them after being told that the
vaccination was entirely safe.
Since rationality involves conceptual flexibility, belief
perseverance is consistent with the view that human beings act at
times in an irrational manner. Philosopher F.C.S. Schiller holds that
belief perseverance "deserves to rank among the fundamental 'laws'
of nature".
