Everyone Who Changed Their Facebook Profile Picture To Rainbows Just Got DUPED Following the legalization of gay marriage and the beginning of pride weekend, many liberal social media users decided to change their Facebook profile picture to include a rainbow filter. Now, its been revealed that this little feature may have actually been a form of psychological testing used to analyze users. The Celebrate Pride tool may have been a quick way to reveal some serious information. This is probably a Facebook experiment! MIT network scientist Cesar Hidalgo wrote on Facebook after changing his picture. The question is, how long will it take for people to change their profile pictures back to normal. Using the filtering tool, Facebook was able to get insight on how to best influence their users in mass. This was not the first time the social network has used a system like this. In 2013, they published a study for which they asked users to change their profile picture to a red equals sign. Of course, Facebook is denying claims that this is anything beyond a declaration of support for the gay community. One spokesman commented that the tool is not an experiment or testeveryone sees the same thing. Its extremely understandable that many people are upset that their behavior may have been manipulated for purely scientific purposes without their consent, behavioral scientist Suzy Moat told reporters, although she acknowledged that many businesses conduct research on how to influence human behavior. What do you think? Was this all a social experiment for Facebook?
