If you have a Facebook account, I guarantee you've seen tons of those little rainbow profile pictures all over your news feed. Is it all just political activism or is Facebook running another psychology experiment?
Last Friday, the United States Supreme Court ruled same-sex marriage as legal across all 50 states. To help users celebrate this news, Facebook added a function called "Celebrate Pride" that allowed people to add a rainbow filter to their profile pictures. This rainbow feature is meant to show users' support of the ruling, but this isn't the first time Facebook offered its users a way to share their political beliefs.
Facebook users saw something like this in 2013 when millions of people turned their profile pictures into the red equal sign to support the human rights marriage equality campaign. According to Facebook officials, over 2.7 million people changed their picture on the first day of the campaign.
But now, users and Internet experts are growing skeptical that Facebook's newest rainbow tool isn't just to help its users support equal marriage rights but to secretly gain information about political trends and your voting habits. All of this might sound like paranoid speculation, but there could be some information to back it up.
