People are less willing to share their views on social media if they believe that their ideas are unpopular, says a study by the Pew Research Center.
The study involves 1,801 adults and shows that this unwillingness could also happen among family, friends and even office colleagues.
The study was conducted in the United States and it mentions Edward Snowden's 2013 revelations of widespread government surveillance program.
The study found that around 80 percent of Americans were willing to have a conversation about the program but only 42 percent of Facebook and Twitter users were ready to post it online.
Among the 14 percent who were willing to discuss about the Snowden issue, only 0.3 percent were willing to post about it on social media platforms.
