Supongamos, no obstante, que se puede desarrollar un algoritmo bancario con un 99 por ciento de precision. Supongamos que en el Reino Unido hay 500 terroristas. El algoritmo identificaria correctamente a 495 de ellos, el 99 por ciento. Pero en el Reino Unido hay aproximadamente 50 millones de adultos que no tienen nada que ver con el terrorismo, y el algoritmo tambien identificaria erroneamente al 1 por ciento de todos ellos, es decir, 500...

Los medios de comunicacion necesitan a los expertos tanto como los expertos a los medios. Todos los dias hay paginas de periodicos e informativos de television que llenar, y un experto que aporte una noticia discordante siempre es bienvenido. Juntos, periodistas y expertos son los artifices de gran parte de la sabiduria conven-cional.

Letting go of the conventional wisdoms that torment us. Letting go of the artificial limits that hold us back--and of the fear of admitting what we don't know. Letting go of the habits of mind that tell us to kick into the corner of the goal even though we stand a better chance by going up the middle.

According to our analysis, the total impact of TV on crime in the 1960s was an increase of 50 percent in property crimes and 25 percent in violent crimes. Why did TV have this dramatic effect? Our data offer no firm answers. The effec..

Now the questions: 1. What color was the car? 2. Did they have fish and chips for lunch? 3. Did they listen to music in the car? 4. Did they drink lemonade with lunch?

Decades of studies have shown that a child born into an adverse family environment is far more likely than other children to become a criminal. And the millions of women most likely to have an abortion in the wake of Roe v. Wade--poor, unmarried..
