Back before everyone and his mature father had a Bluetooth phone everlastingly affixed to their ear, talking on a mobile gaget in public was a fail-safe way to let strangers know just how hectic and imperative you were. At the moment, people just appear to want to talk about what they’re having for dinner. So why can’t we stop eavesdropping? According to investigators at Cornell University, it doesn’t have anything to with your obsessive nosiness. Rather, it’s the speaker’s fault, for conducting a “halfalogue.” (Also known as a one-sided conversation.)
Scientific American writes that halfalogues “make for dissonant eavesdropping because they are unpredictable. The less information we glean from a conversation, the harder our brains work to make sense of what we hear and the more difficult it is to stop listening.” They also “demand more of our attention than dialogues and decrease our performance on other cognitive tasks—whether we are sitting at a computer in the lab, trying to read on the subway or driving a car.”
