People are likely to accept the arguments that fit their system of values and beliefs, without questioning how these arguments support the conclusion.
Similarly, people tend to reject arguments that don’t fit their existing beliefs. This is a very common bias. An example that comes to mind is when somebody who believes in creationism will reject arguments supporting the theory of evolution just because they don’t fit their picture of the world, and ignoring deeper consideration of how these arguments may support the conclusion. Sometimes, just logic is not enough to persuade a person.
