Are we immune to manipulation?

We like to think of ourselves as independently minded and immune to manipulation, and yet imagine others — particularly those of a different political persuasion — as being fantastically gullible. The reality is probably something in between. 

We do know that the posts we see on Facebook have the power to alter our emotions. A controversial experiment run by Facebook employees in 2013 manipulated the news feeds of 689,003 users without their knowledge (or consent) in an attempt to control their emotions and influence their moods. The experimenters suppressed any friends’ posts that contained positive words, and then did the same with those containing negative words, and watched to see how the unsuspecting subjects would react in each case. Users who saw less negative content in their feeds went on to post more positive stuff themselves. Meanwhile, those who had positive posts hidden from their timeline went on to use more negative words themselves. Conclusive: we may think we’re immune to emotional manipulation, but we’re probably not.
