Meghan, The Duchess of Sussex is familiar with online misinformation. Over the past four years, the actor turned duchess turned activist has been the subject of fascination—and extreme scrutiny—across the Internet.

Breaking through that toxicity online to build healthier communities in digital spaces is now a focus of her work with her husband, Prince Harry. Through their new Archewell Foundation, the couple are working with other organizers and activists to address the negative side of social media, from its effects on individuals' mental health to the systemic consequences of disinformation on platforms like Facebook. Prince Harry first spoke out about toxic digital behavior in 2016, when the duchess was subject to racist attacks online as she entered the global spotlight.

In her own life, Meghan told Fortune’s Ellen McGirt, the times when stories about her have spiraled out of control have stemmed from that misinformation. "If you look back at anything I’ve said, what ends up being inflammatory is people’s interpretation of it," the duchess said at Fortune’s Most Powerful Women Summit, which kicked off September 29. "But if you listen to what I actually say"—like encouraging Americans to vote—"it’s not controversial."

Meghan spoke to Fortune’s MPW community, who gathered virtually for the summit, from her new home in California. The Duke and Duchess of Sussex began their work on this issue this year, after leaving their positions as full-time working members of the royal family and moving to North America, first to Canada and then to the United States.

The pair found that reforming online spaces—by connecting with everyone from tech company CEOs to grassroots activists—sat at the intersection of their interests, which spanned veterans' issues, mental health, and gender equality. "It’s like taking two steps forward and five steps backward," the duchess said of doing work to address those needs in the physical world without fixing the way these problems are discussed online.

This summer the duo joined the Stop Hate for Profit campaign, which encouraged advertisers to withhold their advertising dollars from social media companies, especially Facebook, as a way to push those companies to address hate and toxic behavior on their platforms. The boycott specifically responded to the police killing of George Floyd, the Black Lives Matter movement, and racist hate speech online.

"It’s not about trying to take down Facebook, for example," Meghan said during September 29’s discussion. "If the changes that are being made are in fact made, it’s for the good of everyone, Facebook included." But, she added, change has to be long term. "We can’t have this slap on the wrist," Meghan said.

By addressing everything from hate speech to the way social media platforms shape the lives of children and young adults, Meghan—and her husband—hope to propel forward their work on other issues, from gender equity to mental health. "We can all see it and feel it," the duchess said of the problem with so many digital spaces today. "Whether we are directly involved in the online world or not, it’s felt globally. And we know that it’s not sustainable the way that it is."

Ellen McGirt: I wanna focus on a word that you use that I use a lot, which is reckoning. we are really here. We are really facing it.

And I just to prepare for this interview, I listen to a moving graduation speech that you gave. And you not only said black lives matter, you said the names, the people that we've lost, the people that have been murdered. And I was struck by the courage that it took, the effortless courage that it took to keep bringing these things forward, which you do. And that brings me to the moment of reckoning, you're not the only powerful woman even in this community who has had a sitting president take a shot at you. Mobs come at you, And powerful forces try to take you down or try to disparage your message. This is a tough time for people with power and platforms.

What is your best advice for other folks with stakeholders with a desire to weigh in on the important issues of the day? To take those risks carefully, to assess them correctly, and then to weigh in?

Meghan: Yes, I think it's about being authentic. And if you look back at anything that I've said, it's really interesting because it often ends up what ends up being inflammatory, it is people's interpretation of it. But if you listen to what I actually say, it's not controversial.

Actually some of it is reactive to things that just haven't happened, which is in some ways I think you have to have a sense of humour about it, even though there is quite a bit of gravity. And there can be a lot of danger in a misinterpretation of something that was never there to begin with. But that, again, is a by-product of what is happening right now, for all of us. I would say the biggest thing and what I have always stuck to.

That high school graduation speech, I had done it a week or so before I had pre-taped it for them. It was for high 17-year-old girls, right? So the tone and the sentiment while it was going to be a call-to-action was certainly lighter than where we landed after the murder of George Floyd. I knew I couldn't use that tape. And I really struggled if I'm being honest about what to say. And I didn't sit down and write anything. And I didn't ask anyone for help with how I should word this. I was just in tears thinking about it. And I was explaining to my husband why I thought that it was so heart-breaking. Certainly for me to be back in Los Angeles. And it feels so reminiscent to...the state of Los Angeles with the riots after the Rodney king beating. And for these girls to be graduating from high school, which should be a very celebratory time to be plagued with, that unrest felt troubling to me.

So I just spoke from the heart. And that's probably why it doesn't look polished. And that's why it doesn't feel perfect. And but that's also why it's authentic.

I think that is the take-away that I have found is if you don't listen to all the noise out there and you just focus on living a purpose driven life, and you focus on knowing what your own moral compass is. There are always going to be naysayers. But at the end of the day, I used to have a quote up in my room many, many moons ago. And it resonates now perhaps more than ever when you see the visual and noise that can be out in the world. And it's by Georgia o' keeffe. “I have already settled it for myself so flattery and criticism go down the same drain and I am quite free". And the moment that you are able to be liberated from all of these other opinions of what you know to be true, then I think it's very easy to just live with truth and live with authenticity. And I that's how I choose to move through the world.
