Millions were transfixed by video of a couple caught cheating at a Coldplay concert. Some are surprised by the widespread fascination — but perhaps we shouldn’t be.

What made the video compelling was how the cheating couple reacted when the kiss cam found them. It wasn’t rational behavior—they’d have stood a greater chance of getting away with it if they hadn’t hidden.

But their behavior was instinctive. And that recalls the observation of the great Christian apologist CS Lewis: there is an innate universal moral sense encoded in humankind. Whether modern elites concede it or not, in our Judeo-Christian culture, people know violating their marriage vows is wrong, and they’re ashamed when they’re caught doing it.

Here’s one more heartening takeaway: Based on the public reaction, despite decades of elite attempts to undermine traditional sexual mores, much of the American public still cherishes marital fidelity.
