Alcohol is the clearest example of a drug that we, at least in western society, look to as a panacea in spite of a preponderance of evidence that it makes many of our lives worse. The more we rely on it as a social lubricant, the more dependent on it we become — and the worse we become at communicating with one another while not under its influence. In this way, alcohol strikes me as the perfect example of what evolutionary theorist David Krakauer calls a “competitive cognitive artifact” — an “innovation” which, far from improving our overall ability to overcome adversity, actually undermines our ability to function without it.
