However, expert radiologists will often report the sensation of “knowing” that a particular image contains a lesion before they are able to locate it. If we think casually about the process of searching for something, whether a pencil or a malignant tumor, we probably imagine a deliberate process of selecting one location after another for analysis until the target of the search is found or the searcher decides the target is not present. Given the difficulty of this task, it is not surprising that mistakes are made even though errors can be very costly. Searching images for significant clinical findings is a common task for radiologists. An appreciation of the role of nonselective processing may be particularly useful for understanding what separates novice from expert radiologists and could help establish new methods of physician training based on medical image perception.

A second, nonselective pathway extracts information from global or statistical information without selecting specific objects.

Search in scenes may be best explained by a two-pathway model: Object recognition is performed via a selective pathway in which candidate targets must be individually selected for recognition. It is probable that both hardwired guidance by basic features and learned guidance by scene structure become part of radiologists’ expertise. Guidance by basic features (such as color) requires no learning, whereas guidance by complex scene properties is learned. Several high-speed mechanisms guide our search of complex images. How do radiologists glean information from a first glance at an image? It is thought that this expert impression of the gestalt of an image is related to the everyday, immediate visual understanding of the gist of a scene. Now, as the dominance of big tech becomes an explosive societal conundrum, they share their provocative insights and concrete solutions to help everyone understand what is happening, what is at stake, and what we can do to control technology instead of letting it control us.Diagnostic accuracy for radiologists is above that expected by chance when they are exposed to a chest radiograph for only one-fifth of a second, a period too brief for more than a single voluntary eye movement. Troubled by the values that permeate the university's student body and its culture, they worked together to chart a new path forward, creating a popular course to transform how tomorrow's technologists approach their profession. Armed with an understanding of how technologists think and exercise their power, three Stanford professors-a philosopher working at the intersection of tech and ethics, a political scientist who served under Obama, and the director of the undergraduate Computer Science program at Stanford (also an early Google engineer)-reveal how we can hold that power to account. Well-intentioned optimizers fail to measure all that is meaningful and, when their creative disruptions achieve great scale, they impose their values upon the rest of us. This optimization mindset substitutes what companies care about for the values that we as a democratic society might choose to prioritize. System Error exposes the root of our current predicament: how big tech's relentless focus on optimization is driving a future that reinforces discrimination, erodes privacy, displaces workers, and pollutes the information we get.

We have simply accepted a technological future designed for us by technologists, the venture capitalists who fund them, and the politicians who give them free rein. Yet too few of us see any alternative to accepting the onward march of technology. In no more than the blink of an eye, a naïve optimism about technology's liberating potential has given way to a dystopian obsession with biased algorithms, surveillance capitalism, and job-displacing robots. Produktbeschreibung A forward-thinking manifesto from three Stanford professors-experts who have worked at ground zero of the tech revolution for decades-which reveals how big tech's obsession with optimization and efficiency has sacrificed fundamental human values and outlines steps we can take to change course, renew our democracy, and save ourselves.
