Prince Harry has joined a panel which aims to analyse how fake news spreads in communities, one day after he announced he would team up with a Silicon Valley mental health start-up.
The prince will serve as a commissioner on the Aspen Institute's Commission on Information Disorder, the non-profit announced on Wednesday.
The group is chaired by journalist Katie Couric, cybersecurity expert Chris Krebs and civil rights activist Rashad Robinson.
From April, it is to meet several times over six months and speak with experts to find out how misinformation and disinformation spreads in the United States.
A report will then be compiled of their findings, including solutions and recommendations, to be published in the northern autumn.
"The experience of today's digital world has us inundated with an avalanche of misinformation, affecting our ability as individuals as well as societies to think clearly and truly understand the world we live in," Prince Harry said in a statement.
He added it is a "humanitarian issue" which "demands a multi-stakeholder response" from advocacy voices, members of the media, academic researchers, government and civil society leaders.
"I'm eager to join this new Aspen commission and look forward to working in a solution-oriented approach to the information disorder crisis."
Prince Harry has been vocal in the past about the digital world being "unwell" and also faced issues with the media.
In an interview with Oprah Winfrey earlier in March, the prince and his wife Meghan said their decision to step down as senior royals last February was fuelled by negative and racist press coverage.
