The new subject matter gave rise to interesting results that followed a particular pattern.<\/p>\n<p>Consider the blind. They spend their whole lives immersed in sight-dominated societies that speak sight-dominated languages. Based on interactional-expertise theory, their exposure to this language should enable them to make the same judgments as sighted people, even where they are discussing things they have never seen, such as the bounce of a tennis ball, its relationship to the line and how hard it is to call it \u2018in\u2019 or \u2018out\u2019. By contrast, because sighted people lack immersion in blind society, their attempts to pass as blind should come across as more caricatured than authentic. Rather than extrapolating from blind people\u2019s actual discussions of their experiences, sighted people are inclined to imagine by subtraction, guessing, unconvincingly, what it would be like to go through life without seeing.<\/p>\n<p>The other cases yielded similar results: the color-blind were better able to pass as color-perceivers than vice versa, while those with perfect pitch were better able to pass as those without perfect pitch. The reversal of polarity when the color-blind were compared to the pitch-blind was exactly what would be expected. These experiments were a proof of concept, establishing the Imitation Game as a research tool that can reveal interactional expertise in action.<\/p><\/blockquote>\n<p>In more recent experiments, it turns out it was a lot easier for students to pass as gay than Christian.<\/p>\n<p>\u00a0<\/p>\n<h2>110<\/h2>\n<p>C\u2019mon, you\u2019ve got to be a little tempted to learn computer science by now?
