Despite only half the couples making it to the final stage of Married at First Sight, relationship expert Dr Pani Farvid doesn't think the social experiment should be considered a failure.

The reality television show began six weeks ago with six couples paired by Farvid and counsellor Tony Jones, before meeting for the first time at the altar for what was a legal wedding.

The series finishes next week - but already three couples have separated, and two of the remaining three look to be on shaky ground.

"I don't think we can take 100 percent responsibility, because we are not 100 percent in control of other people or the process," Farvid says when asked where the buck should stop for such a low success rate.

Farvid, who says she would "absolutely" sign up for a second season of the show, believes the success or failure of each relationship comes down to a combination of the expert's matches, the approach of the couples and the intensive nature of the process itself.

Some of the separated couples have blamed the experts for making poor matches in the first place.

Lacey Swanepoel said she left the show because she was matched with her "complete opposite".

"The way the show was sold to us was 'we've found your perfect match', but this is much more of a social experiment," she told Stuff after splitting with husband Luke Cederman.

Former participant Dominic Timmon told Stuff the experts needed to explain their choices after his relationship with wife Claire Lawless broke down.

"Listen, if we are going to have the piss taken out of us, then they have to be prepared to have the piss taken out of them too. There's a lot of people wondering what their careers are going to do now," he said.

However Farvid says while it's easy to lay blame elsewhere, she and Jones went into the experiment wanting all the couples to stay together.

"[But] our jobs, out in the real world, are not matchmakers," says the AUT lecturer with a PhD in psychology, who has done extensive research on casual sex, online dating and Tinder.

"Based on the information we had and our interactions with the participants before we matched them, I felt confident that we made the right matches.

"There's only so much I can do, and there's only so much support the production team and the experts can offer the participants."

According to Farvid, a focus on looks over personality and a lack of life experience may have contributed to the downfall of some relationships.

"It was disappointing sometimes to see how looks got in the way of everything else," she says.

"I wonder if sometimes some of the resilience and some of the traits required to move through the experiment successfully come with relational experience and maturity - and that doesn't have to be age-related, but sometimes it is.

"Some more diversity in the age range might be helpful [for next time]."

Over the course of the show, which has been surrounded by scandal, there have been claims some of the participants were only there for fame and to further their careers. Farvid doesn't necessarily buy that. She says at the beginning of the process, she was confident everyone involved was being authentic. But as people tried to tell tales, she knew there was some manipulation taking place.

"As experts, we are outside the narrative, so we know everything that's going on, so sometimes when you tell that story, some people don't like it because they don't realise we know everything that's going on. Some people are trying to project a particular narrative, but that's not really the truth."Read more at:http://www.sheindressau.com/wedding-dresses-sydney | http://www.sheindressau.com/wedding-dresses-brisbane
