Searching for evidence of critical thinking in discourse has roots in a definition of critical thinking put forth by Kuhn (1991),  which places more emphasis on the social nature of discussion and knowledge construction. There is limited research on the role of social experience in critical thinking development, but there is some evidence to suggest it is an important factor. For example, research has shown that 3- to 4-year-old children can discern, to some extent, the differential creditability  and expertise  of individuals. Further evidence for the impact of social experience on the development of critical thinking skills comes from work that found that 6- to 7-year-olds from China have similar levels of skepticism to 10- and 11-year-olds in the United States.  If the development of critical thinking skills was solely due to maturation, it is unlikely we would see such dramatic differences across cultures.
“It’s been to long, Mr. Holmes. Way too long.” He stood, shaking my hand and smiling lightly. “What’s gone wrong in the deduction buisness?” “I…I found this note in one f the suitcases. I knew there was something about that place. It’s written from you…to a man named Rafiel.” I picked out the note and handed it to him, his face lit up and then darkened deeply spat the mention of his name. Who was this guy? Making him feel so…so…emotional? He ripped the note in half, sniffling and running a hand through his hair.
