Pluralistic ignorance
Pluralistic ignorance can be contrasted with the false consensus effect. In pluralistic ignorance, people privately disdain but publicly support a norm (or a belief), while the false consensus effect causes people to wrongly assume that most people think like they do, while in reality most people do not think like they do (and express the disagreement openly). For instance, pluralistic ignorance may lead a student to drink alcohol excessively because she believes that everyone else does that, while in reality everyone else also wishes they could avoid binge drinking, but no one expresses that due to the fear of being ostracized. A false consensus for the same situation would mean that the student believes that most other people do not enjoy excessive drinking, while in fact most other people do enjoy that and openly express their opinion about it.
Multiliteracy
Multiliteracies is a term coined in the mid-1990s by the New London Group and is an approach to literacy theory and pedagogy. This approach highlights two key aspects of literacy: linguistic diversity, and multimodal forms of linguistic expression and representation. The term was coined in response to two significant changes in globalized environments: the proliferation of diverse modes of communication through new communications technologies such as the internet, multimedia, and digital media, and the existence of growing linguistic and cultural diversity due to increased transnational migration. Because the way people communicate is changing due to new technologies, and shifts in the usage of the English language within different cultures, a new "literacy" must also be used and developed.
There are two major topics that demonstrate the way multiliteracies can be used. The first is due to the world becoming smaller, communication between other cultures/languages is necessary to anyone. The usage of the English language is also being changed. While it seems that English is the common, global language, there are different dialects and subcultures that all speak different Englishes. The way English is spoken in Australia, South Africa, India or any other country is different from how it is spoken in the original English speaking countries in the UK.
The second way to incorporate the term multiliteracies is the way technology and multimedia is changing how we communicate. These days, text and speech are not the only and main ways to communicate. The definition of media is being extended to include text combined with sounds, and images which are being incorporated into movies, billboards, almost any site on the internet, and television. All these ways of communication require the ability to understand a multimedia world.
