10 Other Facebook Experiments On Users, Rated On A Highly-Scientific WTF Scale

A former Facebook data scientist who set out to defend the company’s emotion-manipulation experiment on nearly 700,000 users decried the hubbub about it, saying that experiments are happening all the time at the company and that every Facebook users has been part of one at some point. Yes, we can all wear t-shirts saying, “I, too, am a Facebook lab rat.” Most of the “experiments” are A/B testing that’s standard on the Web and rather boring — such as which color blue you’re mostly like to click or how big an ad needs to be for you to notice it — but some are interesting enough to warrant academic write-ups for shedding new light on human behavior.
