People would feel better about their day after an hour-long session in the Fox News rage room—they could groan out their stress, and afterward their problems at work or home were someone else’s fault. It meant that their struggles could be wholly externalized, sparing them the stark reality that maybe their employer didn’t care enough about them to give them a living wage. It would be too painful to admit that perhaps they were being taken advantage of by someone they saw every day rather than the faceless enemy of Obamacare and “illegals.”
In social sciences, a “latent variable” is an element that is influencing a result, but one you haven’t yet observed or measured—a hidden construct that’s floating just out of view. So what is the hidden construct here?
Amos Tversky and Daniel Kahneman conducted a study that asked participants a very simple question: “Suppose you sample a word at random from an English text. Is it more likely that the word starts with a k, or that k is the third letter?” Most people responded with the former, that words that start with k (e.g., kitchen, kite, or kilometer) are more likely. However, the opposite is true, and one is actually twice as likely in a typical English text to encounter words where the third letter is a k, such as ask, like, make, joke, or take. They tested for five letters (k, l, n, r, and v) like this. It is easier for people to think of words by first letter because we are taught to organize (or alphabetize) words by their first letter. However, people conflate this ease of recall with frequency or probability, even when this is far from the truth. This cognitive bias is called the availability heuristic,
Empires preserve their power with the stories that they tell, but just as critical are the stories they don’t—the dark silences they impose, the pages they tear out.
Because longitude represents a distance in the direction of the earth’s daily rotation, measuring it is further complicated by time. Each hour of the day corresponds to fifteen degrees of longitude. If a seaman compares the exact time on his ship to that of his selected reference point, he can calculate his longitude. But eighteenth-century timepieces weren’t reliable, especially at sea.
Because the far-southern seas are the only waters that flow uninterrupted around the globe, they gather enormous power, with waves building over as much as thirteen thousand miles, accumulating strength as they roll through one ocean after another. When they arrive, at last, at Cape Horn, they are squeezed into a narrowing corridor between the southernmost American headlands and the northernmost part of the Antarctic Peninsula. This funnel, known as the Drake Passage, makes the torrent even more pulverizing. The currents are not only the longest-running on earth but also the strongest, transporting more than four billion cubic feet of water per second, more than six hundred times the discharge of the Amazon River.
To “turn a blind eye” became a popular expression after Vice-Admiral Nelson deliberately placed his telescope against his blind eye to ignore his superior’s signal flag to retreat.
To “toe the line” derives from when boys on a ship were forced to stand still for inspection with their toes on a deck seam. To “pipe down” was the boatswain’s whistle for everyone to be quiet at night, and “piping hot” was his call for meals. A “scuttlebutt” was a water cask around which the seamen gossiped while waiting for their rations. A ship was “three sheets to the wind” when the lines to the sails broke and the vessel pitched drunkenly out of control.
