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.

Participate in different subreddits, and demonstrate good reddiquette and you’ll eventually start earning good karma on the site. To see how much good karma you have, click on your username in the upper right and your karma will be displayed. While karma acts as a kind of “street cred” on Reddit and can affect how others view you, it actually has very little impact on how you use the site—unless you want to create and moderate your own subreddit. If you do, your account will need to be at least 30 days old and you’ll need to have a minimal amount of karma in a quantity known only to the site moderators.
