Shocking Psychological Studies and the Lessons They Teach

Rated 5 out of 5 by from Extremely interesting with unusual contents Really interesting with unusual content taught by a gifted lecturer. Outstanding presentation skills combined with well thought out lectures of unusual, fascinating contents. I thoroughly enjoyed the lectures and learned a lot. Good job!

Rated 5 out of 5 by from Excellent course; highly recommended ... but ... I enjoyed the course and I highly recommend it to any student of psychology. The only weakness in the series is the fact that Professor Polk let Milgram's study off way to easy. Although Professor Polk noted the study was shocking due to the methodology (which was appropriate to note), Professor Polk did not note that the study has also had significant replication problems. Further, recent reviews of the original studies have shown that Milgram had cherry picked his results. Yet, Professor Polk left the student with the impression that the results of Milgram are generally valid. Nonetheless, overall a very engaging course and well done by Professor Polk.

Rated 4 out of 5 by from Six Lectures is Not Enough I nearly ignored this course because of the click-bait title "shocking". And the sensationalist disclaimer didn't inspire confidence. But the course is actually a serious discussion about ethics in psychological studies, emphasising the Belmont Principles, although most examples are pre-Belmont. Not for the faint-hearted, easily offended or closed-minded. The course uses words like "evil", "shocking" and "infamous" without careful definition. Rated as 4-star because six lectures are not enough. The Great Courses is currently offering course 2080, White Collar Law, which states "Immoral and unethical is not illegal", upheld by the US Supreme Court. An important distinction, worthy of discussion in this context.This course would lend itself to multiple professors offering different views. Lecture 6 covering deliberate fraud, replication and publishing bias is a course in itself.

Rated 5 out of 5 by from Fascinating and well worth the time! I honestly started watching just to fill my time with something somewhat educational. I did not expect to like the course as much as I did, but I did thoroughly enjoy each lecture. Professor Polk doesn't focus in one extraneous details but instead focuses on the interesting aspects of each study, and each lecture is broken up into very enjoyable segments that is digestible and fun. Well worth it!

Rated 5 out of 5 by from fascinating lectures This was the most amazing set of lectures. Not only were they well presented but they uncovered shocking truths of when "scientists" can run amok. Some of the research had very surprising results too.

Rated 5 out of 5 by from Awesome I loved this course! I would like to see the results of this review! ;) I always heard rumors that many psychological tests were done unethically but I never heard the proof before! I understand more now why people don't trust the "general" opinion of psychologists. But, we do need to go forward and do things right! There is so much to learn!!!!

Lessons from Tuskegee and Facebook
1: Lessons from Tuskegee and Facebook

Today, research with human subjects is guided by a set of three ethical principles of the 1976 Belmont Report, but that was not always the case. In the first lecture of this six-lecture course, Professor Polk explores the famous Tuskegee Syphilis Experiment and how its ethical violations ultimately led to the development of the Belmont Report and the ethical principles it identified.

Pushing Good People to Do Bad Things
2: Pushing Good People to Do Bad Things

Why do good people sometimes do bad things? Professor Polk encourages us to grapple with two of the most famous psychological studies on ethics and human psychology: Milgram’s Obedience Study and the Stanford Prison Experiment. Each study offers invaluable lessons about human behavior. Look at the ways that these explorations into the causes of unethical human behavior were, themselves, astonishingly unethical.

Experimenting on Vulnerable Children
3: Experimenting on Vulnerable Children

Arguably, the most vulnerable people in any population are the children. Childhood development studies can also provide invaluable insights into human psychology. Here, explore two studies where children were the focus: Neubauer’s twin study and Johnson’s “Monster Study” of testing the origins of stuttering. Discover why, according to the Belmont Report’s principles, these “subjects” might be identified more accurately as “victims.”

Testing Psychochemical Weapons
4: Testing Psychochemical Weapons

Government organizations such as the CIA and military are charged with protecting the public, but in these shocking experiments, vulnerable low-ranking soldiers and psychiatric patients were unwittingly subjected to psychoactive drugs. Uncover the ways in which these observational studies lacked both rigorous scientific design and adherence to any of the Belmont Report’s principles. In fact, the results of these studies often led to hallucinations, paranoia, rage, and even death.

Assigning Gender and Spying on Sex
5: Assigning Gender and Spying on Sex

Studies of sex and sexual identity present unique ethical challenges for privacy and consent. In the next two studies, Professor Polk takes you into the private world of sexual identity and impulse. The Tearoom Trade Study considers the public identities and private choices of anonymous public sex participants. The John/Joan case explores the sexual identity of a biologically male child raised as a female.

Current and Future Ethical Challenges
6: Current and Future Ethical Challenges

Science still grapples with the ethics of studying human subjects. Increasingly, data is available about every aspect of human life through our uninhibited interactions with technology. The study of such data sets is affordable, widely generalizable, and easily accessible. But is it ethical? You’ll also discover that the conclusions presented in scientific journals, even under our more rigorous ethical guidelines, may not be as reliable as we thought.

Addiction is a modern-day epidemic...If we ever hope to stem the tide, it is imperative that we develop a better understanding of what addiction is and how it works at a neural level.

About Thad Polk

Professor Thad A. Polk is an Arthur F. Thurnau Professor in the Department of Psychology and the Department of Electrical Engineering and Computer Science at the University of Michigan. He received a B.A. in Mathematics from the University of Virginia and an interdisciplinary Ph.D. in Computer Science and Psychology from Carnegie Mellon University. He also received postdoctoral training in cognitive neuroscience at the University of Pennsylvania.

Professor Polk's research combines functional imaging of the human brain with computational modeling and behavioral methods to investigate the neural architecture underlying cognition. Some of his major projects have investigated differences in the brains of smokers who quit compared with those who do not, changes in the brain as we age, and contributions of nature versus nurture to neural organization. Professor Polk regularly collaborates with scientists at the University of Texas at Dallas and at the Max Planck Institute for Human Development in Berlin, where he is a frequent visiting scientist.

Professor Polk regularly teaches on topics ranging from the human mind and brain, to cognitive psychology, to computational modeling of cognition. His teaching at the University of Michigan has been recognized by numerous awards, and he was named to The Princeton Review's list of the Best 300 Professors in the United States.
