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.
I have found that since there is so much information available on the net, it is extremely important for us to be able to find verifiable and reliable information. Even though most of this can be done by comparing the information with other sources, such as books, encyclopedias, and scientific journals. The Internet contains millions of sites that pertain to this issue but there is no way for anyone to be sure about what the truth really is. And since the Internet itself is the place where the information is most insecure, many people place false information on the Internet so that the people fall into their traps and end up divulging everything. Since there are so many articles and websites available on the Internet, it is very hard to determine what point of view the Internet as a whole is trying to give to the world. But if you are to write the words: “critical thinking” the first 5 results are most likely to be articles that address this issue from various sources. These websites can to give an account of how various people think about this issue. But at the same time, there might be many bogus articles on the Internet also. People sometimes just make up certain information. For instance, one might find an article on the Internet claiming that someone hacked into their computer and used certain private information to drive them bankrupt when this might all be lies. This makes the Internet a very unreliable source because there is no way to confirm and validate the information (unless the information on the websites is taken from some other source). There is a wealth of information available on the Internet and this is both the Internet's weakness as well as strength. The keen researcher should know exactly how to search for the relevant information on the Internet and should also learn to filter the right information from the wrong one by using critical thinking. The Internet, however, also provides some very useful solutions to the problems. There are many software that can be downloaded off the Internet and these can be used to enhance the safety of the computer. Many programs work to strengthen the computer so as to protect it from hackers and other anti-spyware and anti-adware programs do not let any other software to submit private information form computers.
