Bias

We often complain that people are biased with respect to their opinions. The two immediate reasons which I see is the following:-

1.  They are not aware about the contra view, so they follow what they know. One side of the coin. 
2.  They are aware about the contra view, but still prefer to believe that their view is true & right. So they choose to ignore the other side of the coin which may be equally true.

Those people who come in the first type of biased approach are not actually biased per se but they are not well informed so they need our sympathy and we must make them aware about the other view.

Those people who come in the second type of biased approach are the real challenge and they will require a whole different treatment. These people can be attributed to be the fundamentalists as per the definition not exactly in the religious sense but in the intellectual sense of argument. To explain it further these people believe that they are always right and force their views on others, and if you don't follow their view, you will be victimized and can face exclusion.

So the need of the hour is to go back to rationalism and reason out everything based on its merit and demerit and question everything.

P.S Below mentioned are the definitions of the difficult words used above and we can differ on their definitions too.
