Well critical thinking is the process in which the decisions and the point of view about specific things is given by keeping in view the past experiences,beliefs and personal biases.So it really influence the way people behave,talk read or write.If a person is facing positive situation in his life then it would lead to his positive behaviour and if he is facing some bad situations and conditions then he would behave negatively.So whatever he will do will reflect his personal internal condition or way of thinking.So if a person who has to give any information about anything then if he had experienced something negative about it then he would read the information and narrate it in a way which will give negative sense because the information will not be biased free and vice versa.
