Percent

In a recent study of approximately 10,000 undergraduate students beliefs in pseudoscience (Sugarman et al 2011)

78 percent stated that astrology was “very” or “sort of” scientific

48 percent of the science major students stated that astrology has at least some scientific base

When we research or discuss concepts such as psychological literacy, critical thinking or beliefs in pseudoscience we are often referring to the undergraduate population

Most courses on critical thinking or pseudoscience are designed for undergraduate students

Does graduate school make us critical thinkers?

Does being smart make someone a critical thinker?

Glowing examples of this on televisionDr. OzDr. AmanDr. Phil

Examples from the clinical literature and practice

Colin RossDr. Braun and the Satanic PrincessFacilitated CommunicationScott Lilienfeld: Argues that we need to

develop therapies that are both effective and not harmful

Gerd Gigerenzer ◦Statistical and numerical literacy◦Medical Doctors, Politicians and Journalists

Politicians◦Prince Charles and the Foundation for Integrated Health

◦David Tredinnick and integration of horoscopes with health care

Although many of my examples have been clinical, critical thinking and the ability to distinguish science from pseudoscience applies to many areas
