We would all agree that patient-centered care is the utopian ideal: a well-informed individual, educated by experienced, knowledgeable, thoughtful, unrushed clinicians providing unbiased, selfless advice. Unfortunately, but expectedly, this appears to be relatively rare. There are far too many counterproductive incentives, some obvious, many overt, whereas others are more subtle and even subconscious.The operating system of humans is hard-wired with bias, and it is utterly fascinating how presumably wellintentioned physicians present data and offer recommendations. Equally fascinating but utterly sordid is listening to a physician rationalize self-serving advice that conflicts with the best interests of the patient. Similarly, engaged patients often reach erroneous conclusions (because of or despite their physician), deceiving themselves into making what appears to be a poor decision.The science of behavioral economics has blossomed over the past few decades and is well beyond the scope of this amateur author or editorial. For a terse but expansive overview of the psychology of decision making, consider a recent Business Insider article 1 ; for a deeper dive, consider Thinking Fast and Slow by Nobel Prize in Economics winner Daniel Kahneman.Patients can be afflicted with zero-risk bias, outcome bias, information bias, hyperbolic discounting, clustering illusion, anchoring bias, bandwagon effect, or postpurchase rationalization. Physicians fall prey to self-enhancing transmission bias, status quo bias, conservatism bias, or relative value unit/financial bias. Both groups can be deluded by survivorship bias, innovation bias, herding, and confirmation bias ( Table 1).As it relates to prostate cancer, we have been told men should choose to undergo prostate-specific antigen-based screening based on their values and preferences, educated through informed and shared decision making, after thoroughly understanding the risks and benefits. The US Preventive Services Task Force recommends men should have an opportunity to discuss the potential benefits and harms of screening with their clinician and incorporate their values and preferences into the decision. Hooey!! Although I am not aware of existing observational data, I suspect the overwhelming proportion of men in the United States are "assigned" to a screening versus no-screening decision by their physician. It is a rare urologist, let alone primary care physician, who can dually quantify and articulate the intricacies of prostate cancer screening, a concept I find challenging to summarize for a focused conference presentation.Admirably, decision aids strive to equip the individual with high-quality, tempered, and accurate information. Decision aids aim to summarize best available evidence and deliver it via printed material, computer-based, videos, or group sessions. However, not all prostate cancer decision aids are created equal, and many are subject to bias. Ironically and paradoxically, a pooled analysis of 19 randomized studies showed no difference in the decisio...
