In the international bestseller, Thinking, Fast and Slow, Daniel Kahneman, the renowned psychologist and winner of the Nobel Prize in Economics, takes us on a groundbreaking tour of the mind and explains the two systems that drive the way we think. System 1 is fast, intuitive, and emotional; System 2 is slower, more deliberative, and more logical. The impact of overconfidence on corporate strategies, the difficulties of predicting what will make us happy in the future, the profound effect of cognitive (...) biases on everything from playing the stock market to planning our next vacation—each of these can be understood only by knowing how the two systems shape our judgments and decisions. -/- Engaging the reader in a lively conversation about how we think, Kahneman reveals where we can and cannot trust our intuitions and how we can tap into the benefits of slow thinking. He offers practical and enlightening insights into how choices are made in both our business and our personal lives—and how we can use different techniques to guard against the mental glitches that often get us into trouble. Winner of the National Academy of Sciences Best Book Award and the Los Angeles Times Book Prize and selected by The New York Times Book Review as one of the ten best books of 2011, Thinking, Fast and Slow is destined to be a classic.

One way to test vaccines is through human challenge trials in which participants are intentionally infected with a contagious organism to expedite the process of assessing the vaccine’s effectiveness. Some experts believe challenge trials may play an important role in fighting COVID-19, especially if the vaccines under current study do not demonstrate sufficient efficacy, if spread of COVID-19 is controlled to a point that radically slows down traditional trials, or if new vaccines need to be rapidly developed for specific subpopulations.1 (...) Challenge trials involve significant time, burden and risk, requiring participants to spend 3–6 weeks in legal quarantine for 24 hours a day in a high-security facility. During this time, no inperson visitors will be allowed, except for very limited inperson contact from researchers collecting necessary data and checks. Following the quarantine period, participants will be asked to attend numerous outpatient follow-up visits over the course of months, to further monitor their response to the vaccine. Participation involves being away from family who may themselves become sick during the global pandemic, as well as potential fear and mental anguish around being a ‘first’ subject. Because there is no definitive treatment for COVID-19, participants could experience serious illness. But even with milder illness, medical experts know very little about the long-term consequences of COVID-19 infection. This raises the question of how much people should be paid for their participation in COVID-19 challenge trials. Most think participants should be paid something, but many contend that we should be …. (shrink)
