A study (Kramer et al., 2014) was recently published that showed something astonishing — people altered their emotions and moods based upon the presence or absence of other people’s positive (and negative) moods, as expressed on Facebook status updates. The researchers called this effect an “emotional contagion,” because they purported to show that our friends’ words on our Facebook news feed directly affected our own mood.
Nevermind that the researchers never actually measured anyone’s mood.
And nevermind that the study has a fatal flaw. One that other research has also overlooked — making all these researchers’ findings a bit suspect.
