Because such people have their mind sets that they can never be wrong.
Explanation:
Infallibility is something when a person doesn't feel himself wrong. This happens when people have their minds set that they are always right and the other person engaged in the argument with them is wrong, and there is nothing wrong with them. It is actually the inability of themselves to sense their selves wrong.
No one can be infallible. Every human is fallible. So one considering himself fallible is totally wrong. It might happen sometimes that people are right in an argument, but it does not matter that they would always be right. They can be gone wrong sometimes.
It is heard and seen in our daily lives that in an argument with a person who thinks himself infallible, the other person usually says that it is better to keep quiet now, as i know you are never going to consider yourself at mistake.
So it is totally a wrong practice.
