The most shocking things producers discovered for new Duggar documentary

The latest installment of the Duggar family's life story is about to be screened in an Amazon documentary, coming two years after family member Josh Duggar was found guilty of possession of child pornography.

As he serves more than 12 years in prison, "Shiny Happy People: Duggar Family Secrets" walks through the issues that stemmed from Josh and the links the family – made famous in the TLC reality series“19 Kids and Counting" – has to a radical religious sect that People Magazine characterized as "concerning."

The documentary outlines the controversial Institute in Basic Life Principles (IBLP) church and the ways in which the church shaped the family's decisions and behavior.

"There are so many thousands of families that have been hurt by this and have not had a voice, not for lack of trying, for many, many, many years," said Olivia Crist, one of the executive producers. "I mean, hope, the takeaway is really hearing the survivors, hearing what they've been through. And then, I think also for people still in, trapped in a fundamentalist or IBLP group, that hopefully this is a chance for them to say, 'Hey, it is possible to get out and that they're not alone.'"

"Josh Duggar is really the tip of the iceberg in this group," she confessed in the documentary.

Prior to Josh's arrest, he confessed to molesting young girls. Among those were his sisters Jill Duggar Dillary and Jessa Duggar Seewald.

Crist revealed that Josh grew up "in a system that is inherently abusive and [has a] lack of sex education." That kind of environment, she explained, "breeds abuse" by blocking children from any other adults in their lives.

"I think throughout the show, we see that in so many different areas," she told People. "And systems like this, that's, unfortunately, how they're set up with this authoritarian [notion of] 'men have all the control and women and children have to be submissive to that control' — I think that is just a recipe for absolute disaster."

In March, Jinger (Duggar) Vuolo released a tell-all book about the "darker side" of growing up in the family and the church. She described it as an "unhealthy version" of Christianity.

"I was just so crippled with fear, and I didn’t know why,” she told The New York Times in an interview.

Amy (Duggar) King similarly has attacked her aunt and uncle for protecting their son Josh, despite knowing he was a predator.

"I don't think anyone would make the mistake of assuming I support my cousin," Amy wrote to People in May 2022. "I'm struggling to even find the words to express how angry I am. I'm angry at my cousin. I am deeply disappointed in him as a person. ... But let me tell you I am furious at the family that looked the other way and still today, refuse to hold him accountable."

Crist also revealed Jill "was hesitant" to tell her story. "I won't speak for her fully on that. But yes, I think at the end of the day we're just really honored and humbled that they trusted us with their stories."

Calling it a "cult," Crist said that the documentary goes into a lot of abuse that happens under the guise of a church. She noted that they researched just "how far and wide the IBLP ideology went."

"It went into our police system. It went into the military. And I think also, just how far and wide, like I said, the ideology spread," she said. "You can speak to a family who is part of IBLP Australia or part of IBLP and live in Tennessee and you're going to see the same exact thing happen in terms of really just this pandemic of abuse that Gothard's teachings inhabit."

Another executive producer, Julia Willoughby Nason, said she found it "shocking" while listening "to survivor stories." Talking to People, she thinks "the far-reaching quality of this ideology was extremely shocking to me, especially how it's so ingrained in our modern-day culture present day with the political stakes of our human rights at play here."

"I feel like being a woman in this culture, whether I'm coming from a place of a high control system as IBLP or coming from not that place, just inherently being a woman, I could identify with the themes of abuse and trauma that we're going through these people's lifelines," she added.

There were so many things that they discovered that they had to start editing. It's a four-part series, but she explained the IBLP has been around since the 1960s, and there's room for future episodes.

"There's certainly a lot more we could say," Crist explained. "And I think, too, where we land, the last episode is a jumping-off point for this larger political conversation, is also something that is of interest of further exploring."

Nason isn't merely an EP on the project, her documentaries frequently focus on "exposing the underbelly of systems of control." Her work includes a Trayvon Martin documentary and one about the fake concert/scam Fyre, and she's currently at work on a mini-series about the Murdaugh murders.

"But one of the things I want to highlight is really the educational neglect that happened to a lot of these children is really astonishing. Their education was not sufficient," Crist also. "There are organizations out there — the Coalition for Responsible Homeschooling is one great one — that are doing really good work to advocate for the rights of children."

The trailer for the documentary reveals that the Duggars are only the tip of the IBLP plan that involves training them in political engagement, sending their children into the halls of Congress, and to intern in the White House.
