Years ago, on the first of April, someone sent me a story that was just plausible enough. I won't dress it up: it wasn't clever, it was simply well-aimed. It landed on something I already half-believed, it arrived with the right details in the right order, and within a minute I'd forwarded it to two friends with a “did you see this?” One of them wrote back with a single line: you do know what day it is. And there it was — the small, particular heat of having been caught out. Not harmed, not fooled about anything that mattered. Just duped, and having pressed the button before I'd thought.

I've come to be almost grateful for that feeling, because it taught me something I use constantly now. For years, April did a quiet job on me. In the last days of March a kind of filter would switch on — a low wariness of anything that seemed a bit too neat, too perfectly shaped to what I wanted to hear. I'd read the breaking thing that morning and hold it at arm's length for a beat before believing it. Then the second of April would come, the filter would switch off, and I'd go back to taking the world more or less at face value.

That filter doesn't get to switch off any more.

The reason won't surprise anyone who's opened a social feed lately. Generative AI has given every ordinary day the texture the first of April used to have all on its own: the image that's a little too on-the-nose, the quote that's a bit too perfect, the clip that shows you exactly the thing you most wanted, or most dreaded, to be true. None of it announces itself. It sits in the feed looking like everything else, almost believable, which was always the giveaway with a good April Fool. The trick was never the outrageous lie. It was the one you could imagine being real.

So the once-a-year discipline has to run all year now, and that sounds exhausting until you notice what the discipline actually is. The lesson April taught me was never to be cynical. Cynicism is a mood: it's easy, it costs nothing, and it's every bit as lazy as believing everything, because the cynic doesn't check either. He's simply decided the answer in advance. What April taught was discernment, which is a skill, and the difference between the two is the whole point. You don't get to trust by default any more. But you can still trust on purpose, and that's a far better place to stand than a permanent crouch of suspicion.

The tells, all year round

What does trusting on purpose actually look like? Mostly it's a handful of ordinary instincts that I used to save for one day in spring.

The first is that word — almost. The things that get past us are rarely the wild ones; they're the ones that seem almost right. So the very plausibility of a thing, the way it slots so neatly into what I already think, has become a reason to slow down rather than a reason to nod along.

The second, and the one I lean on most, is the tug. There's a specific pull you feel when something has been built to be shared — a little jolt of delight or outrage, a sense that people need to see this. I've learned to treat that tug not as a signal to act but as the alarm going off. The stronger the urge to share before I've checked, the better the odds the thing was made to produce exactly that urge. The pause that follows — the small act of noticing the pull before I act on it — is the same attention that any mindfulness practice trains: the beat between the stimulus and the response, where all the useful choices live.

And then, in that beat, three questions I run before I pass anything on. Where did this actually come from, not who posted it but where did it start? Who gains if I believe it? And is it pitched a little too precisely at my delight, or my anger? None of that needs expertise. It needs the willingness not to amplify something I couldn't stand behind if a friend asked me straight: is this true, or did you just want it to be?

I don't always manage it, for what it's worth. The ones that still catch me are the ones that flatter something I already wanted to be true — the pause is hardest exactly when I'd most like to skip it.

What it costs

I won't pretend the discipline is free, because it isn't, and the cost is the part most people skip over. Vigilance is tiring. Holding everything at arm's length for a beat, all day, every day, quietly takes something from you — the easy, default trust that used to make scrolling a pleasant, idle thing rather than a low-level exercise in verification. There was a time I could read a thing and simply enjoy it, or believe it, or be moved by it, without a small auditor at the back of my head asking where it came from. I miss that. I'd be lying if I said the skill had come without a loss, and I'm wary of anyone who sells it as pure gain.

There's a stranger cost further out, too. Once everyone knows that anything could be fake, the genuinely real thing can be waved away as fake whenever it's inconvenient: the true photograph, the actual recording, dismissed with a shrug and a “that's probably AI”. A world that can't be fooled by anything can also refuse to believe in anything, and that's arguably the more dangerous end of it, though I'm honestly not sure which of the two costs will matter more. Discernment has to keep room for yes, this one is real, or it curdles straight back into the cynicism I've been trying to avoid.

Friends ask me some version of the same question now, half-joking and half-not: how are you meant to trust that anything's real any more? My answer has settled into something fairly plain. You don't get trust for free the way we used to; that particular gift of the early internet is gone, and it isn't coming back. But trust was never really meant to be free; we'd just grown used to spending it without thinking. What you can still do, every single day, is choose it deliberately — look at the thing, feel the tug, take the beat, ask the questions, and then decide. That's not despair, and it isn't cynicism; it's just discernment, practised on purpose, the way I once practised it for a single day in April — and I'd far rather hand my friends that than a reason to trust nothing at all.
