The popularity of Facebook has generated numerous discussions on the individual-level effects of social networking. However, we know very little about people's perceptions of the effects of the most popular social networking site, Facebook. The current investigation reports the findings from a survey designed to help us better understand young people's estimates of the perceived negative effects of Facebook use on themselves and others in regard to three outcome categories: (1) personal relationships, (2) future employment opportunities, and (3) privacy. Congruent with Davidson's third-person effect theory, respondents, when asked about the three outcome categories, believed that the use of Facebook had a larger negative impact on others (e.g., "your closest friends," "younger people," "people in your Facebook network of friends," and "Facebook users in general") than on themselves. Overall, results were inconclusive when it came to the link between the third-person perceptual gap and support for enhanced regulation of Facebook. Implications and limitations of this research are discussed.

You are time-biased if you have systematic preferences about when events happen. There are different varieties of time bias. Near-biased agents discount events as they are scheduled further in the future. Future-biased agents discount events because they have already occurred. This book argues that it is irrational to be time-biased. In the process it develops the theory of temporal neutrality for rational planning. The first part (Chapters 1–4) describes two arguments against near bias: one based on well-being and one based on arbitrariness. It also develops a theory of egoistic concern. The second part (Chapters 5–7) argues that structurally similar arguments can be mounted against future bias. In the process it diagnoses issues we have understanding and measuring past discounting. The final part (Chapters 8–11) explains why we are time-biased and shows how the theory of temporal neutrality can help us determine when to stick to our past commitments, how to value an afterlife, and how to discover meaning in life even if we cannot make a permanent difference in the world.

This research explores white-black differences in adolescent heterosexual romantic involvement and how these differences are shaped by social context. We find that, parallel to patterns of marriage in adulthood, Non-Hispanic white girls are more likely to be in a romantic relationship than African American girls. This is particularly true when we focus on heterosexual romantic relationships formed with schoolmates. Among boys, African Americans are more likely to be romantically involved than Non-Hispanic whites. We investigate the contribution of two broad types of social-demographic factors to these race-ethnic differences, population composition and normative climate. We develop theory about why being a numerical minority should lead to lower levels of relationship formation, especially when interracial relationships are rare. Results support the population composition hypotheses but not the idea that race-ethnic differences arise because of differences in normative climate.
