being knowledgeable and being intelligent are not the same. Being knowledgeable generally refers to having access to information and facts as well as the ability to recall them. Intelligence usually refers to a person’s ability to reason, solve problems, think critically, comprehend subject matter, use language to communicate effectively, construct relationships, employ logic, and manipulate numbers (Gardner, 1999)

Experiencing diversity challenges expectations not only by increasing acceptance of different cultural, ethnic, and racial groups but also by enhancing students’ overall psychological functioning (Crisp & Turner, 2011). Pascarella (1996) reached a similar conclusion from the national study of student learning that found that diversity experiences in the first year of college had long-term positive effects on critical thinking throughout college, particularly for white students.

Learning how to express emotions within a social system is knowledge acquired through social interaction governed by the rules and customs of the culture. One culture may encourage open and intense expression of emotional feelings, whereas another may see that same behavior as inappropriate. The exception is primal emotions, such as fear when confronted by a predator. Emotional expression is a matter of how much or the degree to which one expresses an emotion. Plutchik’s (1980) eight basic emotions include continuums from minimal to extreme expression: Trust: acceptance to admiration Fear: timidity to terror Surprise: uncertainty to amazement Sadness: gloominess to grief Disgust: dislike to loathing Anger: annoyance to fury Anticipation: interest to vigilance Joy: serenity to ecstasy Combinations of these basic emotions create other forms of expressions. For example, the combination of the emotions joy and trust produce love, while the combination of the emotions anticipation and anger produce aggression (Plutchik, 1980).

randomised, controlled experiments tell us over and over again that when higher-ranked items connect with web pages that favour one candidate, this has a dramatic impact on the opinions of undecided voters, in large part for the simple reason that people tend to click only on higher-ranked items. This is truly scary

search engines are influencing far more than what people buy and whom they vote for. We now have evidence suggesting that on virtually all issues where people are initially undecided, search rankings are impacting almost every decision that people make
