  1. 6.3 Ethics in Statistics

  2. Minimizing Risk vs. Maximizing Info • To test a new surgical practice, should you account for the placebo effect by performing some sham surgeries where you cut the person open, but don’t do anything? • This is why we test on animals before we test on people • To avoid a negative placebo effect, is it ok to not tell the subjects of possible negative side-effects?

  3. Informed Consent • Before you can begin a study, each subject must give informed consent. • You must inform people of all potential risks • To account for a negative placebo: both groups are told the risks of the drug that they may or may not get • Even for a survey, no physical harm is possible but the possibility for emotional harm remain • You might ask a question related to a traumatic event. • It’s best to inform the subject the topic of the survey before asking the specific questions. • Minors can’t legally give consent, so you must ask their parent/guardian

  4. Informed Consent: What is Informed? • Inform subjects about ALL potential risks • Inform subjects of alternative treatments to their disease/ailment • Is it really informed if the subject signs without reading the 6+ pages?

  5. Institutional Review Board (IRB) • Every company, university, institution that conducts research involving human subjects has an IRB. • They must give approval before any clinical trial may begin no matter what • Even if you’re just surveying students on how they feel about a type of lecture aid, that data can’t be published if the IRB didn’t give approval. • Exist solely to protect the rights and welfare of human subjects • Not concerned with the purpose or validity of the study

  6. Confidential vs. Anonymity • It is important you are ethical in your treatment of private information • Confidential: Personal information is kept secret and not released • Example: I tell you the average test score, but not the scores of individual students • Anonymity: Even the person conducting the survey doesn’t know who said what • Example: The survey in the beginning of the year was anonymous because I had you not write your names on the survey

  7. Current vs. Future Risks • In the pharmaceutical industry, nothing is worse than putting a drug on the market that has to get recalled because its too dangerous • Experimental drugs are tested on animals first, but there is still a lot more risks because there is much of the drug that we don’t know • Sample Size: more data vs. more people at risk • The control group. Is it ethical to have a group with a real disease receive no medical treatment for the period of the trial?

  8. Clinical Trials • There is an established procedure for bringing new drugs onto the market. • 1) Cell Cultures & Computer Models: work with nothing living. • 2) Animal Testing • 3) Phase I Clinical Trials: Test the drug on a small number of healthy people who don’t have the drug… why? • Testing for side effects. Something that harms a healthy person could be fatal to someone who already has a compromised immune system. • Figure out appropriate dosage

  9. Clinical Trials • 4) Phase II Clinical: Test the drug on a small number of people who have the disease (100) • Is it more effective than current treatments? • The control group takes the current treatment… compare new vs. current NOT new vs. nothing • Are the side effects too harmful? • 5) Phase III Clinical Trials: Test the drug on a large number of people who have the disease (1,000’s) to collect a wealth of data and lower the error from variance on our experimental data

  10. Clinical Trials • 21% of drugs in Phase I fail to reach Phase II • 30% of drugs in Phase II fail to reach Phase III • 32% of drugs in Phase III fail to make it to the Market • Counting all the failed attempts, it costs about $800 million over 12 to 15 years to develop one new drug and bring it to the market.

  11. Ethical Violations • After prosecuting those who violate ethics, is it ethical for us to use the data or should we throw it out? • Almost all of our knowledge about how the human body reacts to freezing is based off of Nazi experiments from the concentration camps. • Page 298 • Example 6.19: An example of racism and ethical violations in the US from 1930 to 1970 • Story in margin, dishonesty in Russia
