Twenty percent of the students at your university are in a sorority or fraternity. You see that many of the students in your class of 200 students are wearing shirts with Greek letters on them. You conclude that half of the students are in a fraternity or sorority. Of what bias are you possibly guilty?

Insensitivity to prior probabilities.

Explanation: In a bid to make inference based on a given data or information, people may tend to base their conclusion on representativeness. In the scenario above, I concluded that half of the students in my class of 200 are in a fraternity or sorority. However, the baseline probability was that 20% of students in the university belong to a fraternity or sorority. Here, I have used the baseline probability to make inference or guess the probability that students who wore shirt with Greek letters on them belonged to fraternities or sororities even though no description was given about students in my class.

new communications technology has affected the way social movements are organized because nowadays, social movements rely on social networks and the media to get different people with a similar way of thinking in contact, and thus, get them to mobilize for a greater cause.

individuals only participate in collective action when they feel identified with it. is in this aspect that social media becomes relevant, because it guarantees communication among all individuals and organizes the social actions that are going to be carried out, i.e., the social movements.

in addition, being covered by the media is important to validate the message and make it relevant in the social agenda, as well as to reach more people who can share interests, appealing to public sympathy for their cause.

in conclusion, it is by social networks and social media that social movement is given birth; by connecting different individuals with similar ideas and organizing them to mobilize for a greater cause.
