As we are going into the era in which a variety of information flows on the network, and we are not able to know the background of the disseminator, we must check the information itself using the knowledge and information we already possess. Logical induction is a procedure for this activity. Another procedure which an audience may use to face the information chaos is cross media verification. As Cantril pointed out, a simple and easy way to check information is to check it across several media. The audience must avoid relying on a single source.
Media literacy promotes the practice of comparing the structure and motivation of different media.
In our information environment today, we need to compare the media that have different backgrounds. In Cantril's case, some people checked other radio stations. Although the checking was effective at that time, they were checking only the same kind of media. What we need today is to compare the media that have different dimensions. Examples of comparison pairs are electronic media and printed media, popular media and quality media, international media and domestic media, main stream media and alternative media, and so forth.
