Facebook recently ran a quite interesting test. The famous social network actually decided play with the emotions of its users. Facebook conducted a massive psychology experiment and has just published the results it obtained.
Scientists at Facebook have published a paper which shows that they manipulated the emotions of more than 600,000 users. It seems that what the social network wanted was to determine if they will be able to affect the emotional state of its users.
The paper was published in The Proceedings of the National Academy of Sciences. It can be found under the name of Experimental evidence of massive-scale emotional contagion through social networks. The test reveals that scientists have been able to influence positive and negative posts of some randomly selected users.
The test tried to find out if emotional stress can be transmitted across a social network. What they wanted to discover is if people can respond with positivity or negativity to certain posts. Naturally, not all users were happy with the fact that they were subject of study for Facebook. Still, unfortunately for them, there is nothing they can do.
When you sign in to Facebook you are required to agree with the Facebook Data Use Policy. This gives the famous social network the right to access, as well as to use the information you provide and post on Facebook. Of course, this means that Facebook has the right to use any data or conduct the study it wants. The use of users data for advertising is a well-known practice now.
