Can AI predict someone's breakup? - Thomas Hofweber

You and your partner Alex have been in a strong, loving relationship for years,

and lately you're considering getting engaged.

Alex is enthusiastic about the idea, but you can’t get over the statistics.

You know a lot of marriages end in divorce, often not amicably.

And over 10% of couples in their first marriage get divorced

within the first five years.

If your marriage wouldn’t even last five years,

you feel like tying the knot would be a mistake.

But you live in the near future,

where a brand-new company just released an AI-based model

that can predict your likelihood of divorce.

The model is trained on data sets

containing individuals’ social media activity,

online search histories, spending habits, and history of marriage and divorce.

And using this information,

the AI can predict if a couple will divorce

within the first five years of marriage with 95% accuracy.

The only catch is the model doesn’t offer any reasons for its results—

it simply predicts that you will or won’t divorce without saying why.

So, should you decide whether or not to get married

based on this AI’s prediction?

Suppose the model predicts you and Alex

would divorce within five years of getting married.

At this point, you'd have three options.

You could get married anyway and hope the prediction is wrong.

You could break up now,

though there’s no way to know if ending your currently happy relationship

would cause more harm than letting the prediction run its course.

Or, you could stay together and remain unmarried,

on the off-chance marriage itself would be the problem.

Though without understanding the reasons for your predicted divorce,

you’d never know if those mystery issues would still emerge

to ruin your relationship.

The uncertainty undermining all these options

stems from a well known issue with AI around explainability and transparency.

This problem plagues tons of potentially useful predictive models,

such as those that could be used to predict which bank customers

are most likely to repay a loan,

or which prisoners are most likely to reoffend if granted parole.

Without knowing why AI systems reach their decisions,

many worry we can’t think critically about how to follow their advice.

But the transparency problem doesn’t just prevent us

from understanding these models,

it also impacts the user’s accountability.

For example, if the AI's prediction led you to break up with Alex,

what explanation could you reasonably offer them?

That you want to end your happy relationship

because some mysterious machine predicted its demise?

That hardly seems fair to Alex.

We don’t always owe people an explanation for our actions,

but when we do,

AI’s lack of transparency can create ethically challenging situations.

And accountability is just one of the tradeoffs we make

by outsourcing important decisions to AI.

If you’re comfortable deferring your agency to an AI model

it’s likely because you’re focused on the accuracy of the prediction.

In this mindset, it doesn’t really matter why you and Alex might break up—

simply that you likely will.

But if you prioritize authenticity over accuracy,

then you'll need to understand and appreciate the reasons

for your future divorce before ending things today.

Authentic decision making like this is essential for maintaining accountability,

and it might be your best chance to prove the prediction wrong.

On the other hand, it’s also possible the model

already accounted for your attempts to defy it,

and you’re just setting yourself up for failure.

95% accuracy is high, but it’s not perfect—

that figure means 1 in 20 couples will receive a false prediction.

And as more people use this service,

the likelihood increases that someone who was predicted to divorce

will do so just because the AI predicted they would.

If that happens to enough newlyweds,

the AI's success rate could be artificially maintained

or even increased by these self-fulfilling predictions.

Of course, no matter what the AI might tell you,

whether you even ask for its prediction is still up to you.
