National Geographic’s ‘Microphone of Truth’ Rolls Out To Prevent Fake News

National Geographic is upgrading investigative journalism to the next level because fake news is one of the hottest topics this year.

Therefore, NatGeo Latin America has developed a project to promote their very first investigative journalism show called “Explorer Investigation”. The broadcaster has developed “Microphone of Truth”, a tool which has the ability to detect user’s voice and heart rates to clarify the accuracy.

To create Microphone of Truth,  the company worked with MediaMonks agency.  If a person tells the truth, the microphone goes green, yet otherwise if they lie, it goes red. In discrepancy, the microphone shines yellow.


The tracking of the tool is very simple and clear: The use of the tool turns the clock back to a time when the topic was assumed to be accurate. According to Alex Mendes, Nat Geo Partners Latam head of creative services,

It is impossible to say whether anyone is lying or telling the truth with 100% certainty. The idea was to reinvent the old microphone in a time of fake news.


Alike The Columbia Journalism Review and The News Literacy Project,  Microphone of Truth aims to tackle the fake news, especially in Latin America and courage people to stay away from them. Plus, it is a tool to put on a bit of fun and interest to the typical politician and celebrity discussion.

Probably like in any kind of of polygraph, there can be errors. Anyhow, it happens to be a helpful tool promote the upcoming investigative journalism show of NatGeo which is set to debut in September.
