    Americans Reject Tailored Advertising and Three Activities That Enable It
    (2009-09-01) Turow, Joseph; Bleakley, Amy; King, Jennifer; Hennessy, Michael; Hoofnatle, Chris Jay
    This nationally representative telephone (wire-line and cell phone) survey explores Americans' opinions about behavioral targeting by marketers, a controversial issue currently before government policymakers. Behavioral targeting involves two types of activities: following users' actions and then tailoring advertisements for the users based on those actions. While privacy advocates have lambasted behavioral targeting for tracking and labeling people in ways they do not know or understand, marketers have defended the practice by insisting it gives Americans what they want: advertisements and other forms of content that are as relevant to their lives as possible. Contrary to what many marketers claim, most adult Americans (66%) do not want marketers to tailor advertisements to their interests. Moreover, when Americans are informed of three common ways that marketers gather data about people in order to tailor ads, even higher percentages - between 73% and 86% - say they would not want such advertising. Even among young adults, whom advertisers often portray as caring little about information privacy, more than half (55%) of 18-24 years-old do not want tailored advertising. And contrary to consistent assertions of marketers, young adults have as strong an aversion to being followed across websites and offline (for example, in stores) as do older adults. This survey finds that Americans want openness with marketers. If marketers want to continue to use various forms of behavioral targeting in their interactions with Americans, they must work with policymakers to open up the process so that individuals can learn exactly how their information is being collected and used, and then exercise control over their data. We offer specific proposals in this direction. An overarching one is for marketers to implement a regime of information respect toward the public rather than to treat them as objects from which they can take information in order to optimally persuade them.

    Multiple Method Contraception Use Among African American Adolescents in Four US Cities
    (2011-06-01) Hennessy, Michael; Brown, Jennifer L; Sales, Jessica M; DiClemente, Ralph J; Salazar, Laura F; Vanable, Peter A; Romer, Daniel; Carey, Michael P; Valois, Robert F; Brown, Larry K; Stanton, Bonita
    We report on African American adolescents' (N = 850; M age = 15.4) contraceptive practices and type of contraception utilized during their last sexual encounter. Respondents completed measures of demographics, contraceptive use, sexual partner type, and ability to select “safe” sexual partners. 40% endorsed use of dual or multiple contraceptive methods; a total of 35 different contraceptive combinations were reported. Perceived ability to select “safe” partners was associated with not using contraception (OR = 1.25), using less effective contraceptive methods (OR = 1.23), or hormonal birth control (OR = 1.50). Female gender predicted hormonal birth control use (OR = 2.33), use of less effective contraceptive methods (e.g., withdrawal; OR = 2.47), and using no contraception (OR = 2.37). Respondents' age and partner type did not predict contraception use. Adolescents used contraceptive methods with limited ability to prevent both unintended pregnancies and STD/HIV. Adolescents who believed their partners posed low risk were more likely to use contraceptive practices other than condoms or no contraception. Reproductive health practitioners are encouraged to help youth negotiate contraceptive use with partners, regardless of the partner's perceived riskiness.

    Public Understanding of and Support for the Courts: Survey Results
    (2007-01-01) Jamieson, Kathleen Hall; Hennessy, Michael
    Using data from two nationally representative surveys, we examined public knowledge about the Constitution and courts: the impact of court exposure and news sources on perceptions of the courts, trust in the courts, perceptions of bias in the courts, and willingness to curb the power or influence of the courts. The surveys were conducted in the summers of 2005 and 2006 by Princeton Survey Research Associates International for the Annenberg Public Policy Center of the University of Pennsylvania. Each has a margin of error of plus or minus three percent (details can be found in the Appendix). Unless otherwise indicated, the reported results are drawn from the 2006 survey.

    How Sources of Sexual Information Relate to Adolescents' Beliefs About Sex
    (2009-01-01) Bleakley, Amy; Hennessy, Michael; Fishbein, Martin; Jordan, Amy
    Objectives: To examine how sources of sexual information are associated with adolescents' behavioral, normative, and control beliefs about having sexual intercourse using the integrative model of behavior change. Methods: Survey data from a quota sample of 459 youth. Results: The most frequently reported sources were friends, teachers, mothers, and media. Regression analyses indicated that learning about sex from parents, grandparents, and religious leaders was associated with beliefs likely to delay sex; friends, cousins, and media were associated with beliefs that increase the likelihood of having sexual intercourse. Conclusions: Different sexual information sources were associated with different underlying beliefs.

    Internet Privacy and Institutional Trust: Insights From a National Survey
    (2007-04-01) Turow, Joseph; Hennessy, Michael
    What does the US public believe about the credibility of institutional actors when it comes to protecting information privacy online? Drawing on perspectives of environmental risk, this article addresses the question through a nationally representative telephone survey of 1200 adults who go online at home. A key result is that a substantial percentage of internet users believes that major corporate or government institutions will both help them to protect information privacy and take that privacy away by disclosing information to other parties without permission. This finding and others raise questions about the dynamics of risk-perception and institutional trust on the web.

    Americans, Marketers, and the Internet: 1999-2012
    (2014-04-11) Turow, Joseph; Bleakley, Amy; Delli Carpini, Michael X; Bracken, John; Draper, Nora A; Hennessy, Michael; Feldman, Lauren; Good, Nathaniel; Grossklags, Jens; Hoofnagle, Chris Jay; Howard-Williams, Rowan; King, Jennifer; Li, Su; Meltzer, Kimberly; Mulligan, Deirdre K; Nir, Lilach
    This is a collection of the reports on the Annenberg national surveys that explored Americans' knowledge and opinions about the new digital-marketing world that was becoming part of their lives. So far we’ve released seven reports on the subject, in 1999, 2000, 2003, 2005, 2009, 2010, and 2012. The reports raised or deepened a range of provocative topics that have become part of public, policy, and industry discourse. In addition to these reports, I’ve included three journal articles — from I/S, New Media & Society and the Journal of Consumer Affairs — that synthesize some of the findings and place them into policy frameworks. The journals have kindly allowed reproduction for this purpose.
