Abstract
Post-Truth is a novice concept and it has developed as a radical ideology of post modernization. Post truth has emphasized on political, economic, social, cultural and technological aspects of power holders and its hegemony toward the poor nation. Power holders are misusing all forms of media including social media. Facebook, Twitter/Instagram/ Youtube/Whatsapp etc are especially misused to extend the power of regime. Post-truth prioritizes on disinformation for manipulating the perceptions of the people throughout the world. Social media has accused of misusing secret information. Accuracy, Balance and Credibility are no more in information. Social Media cannot play the role of watchdog of society. It cannot fulfill its duty as a gatekeeper. Media has to promote as a mirror of society but in post-truth ideology, it may not be acceptable in all conditions. In fact, it will destroy the professional standard.
