Hello loves, Julian here for DNews. Alright, first of all, the oft-quoted statistic that 50% of marriages fail is just plain wrong.

The actual number for first marriages is closer to 20-25%, but that still begs the question.

Why do they fail? Why do people who have avowed themselves to one another for their whole lives come up short?

Well, John and Julie Gottman have been pondering that question for decades.

By the way, they’re both psychologists, and yes, they’re married. Feel free to "d’awwww" now.

According to the Gottmans, you can actually predict with 94% certainty which relationships will be healthy and which will be festering quagmires of misery and stress simply by how they support each other.

Anyone who’s been in a relationship knows that sometimes you and your partner’s interests don’t align.

Maybe you like hockey but they’re not so hot in it.

Or maybe they like camping and you understandably think sleeping on the dirty ground in the woods with no wifi is a terrible way to spend a vacation.

But when one person tries to share their interests with their significant other, that’s a bid for emotional support.

How often they get that acknowledgment makes all the difference.

John Gottman conducted a study where he invited 130 newlywed couples to what looked like a bed and breakfast, but was actually a lab where they could observe the subjects.

He was watching for how often one person would say something seemingly inconsequential, like, "Hey, check out that bird!" or, "I have the weirdest feeling we’re being watched right now."

Gottman called these "bids" for emotional support, and noted how often their partner would respond in a meaningful way.

Their findings show that couples stay together when they show bids of interest or support 9 out of 10 times, while couples who only support each other one third of the time split within six years.

Ignoring those bids for support and acceptance can have an actual physiological effect.

The Gottmans and a team of researchers brought in newlyweds to interview them.

They were asked some pretty tough questions on their relationships while electrodes monitored their heart rates, blood flow, and sweatiness.

While across the board, everyone responded calmly to the questions, some couples showed higher heart rates, blood flow, and sweat production.

In other words, their palms were sweaty, knees weak, arms were heavy.

They’re nervous, but on the surface they look calm and ready.

The stress of being in the same room as their spouse and talking about their relationship caused their sympathetic nervous system to kick in and they had a fight-or-flight response.

Those couples were usually divorced within 6 years.

So if you want to have a healthy and less stressful relationship, it’s important you both work actively to support each other’s emotional bids, even if camping is just the worst.
