Politicians Need to Understand This Computer Science Concept Better - Facts So Romantic

I have an idea that would keep 100 percent of foreign-born terrorists out of the United States. All we have to do is this: Never let anybody in. Most of us find this idea ludicrous, of course, and rightly so. Keeping out terrorists is not the only goal of border policy; it's essential that the vast majority of people can come and go freely, whether for pleasure, business, or survival. Yet many of our decisions are based on similarly shoddy reasoning: We often fail to consider that there are two sides to the accuracy seesaw. For example, we celebrate mammograms for detecting 84 percent of breast cancers and bemoan when law enforcement can't access a phone, but we overlook how often mammograms detect fictitious cancers, or how many hackers were foiled by encryption.
