We don't make bad decisions because we're stupid. We make bad decisions because we often compare reality to fantasy.
You think of your current job, your relationship, the city you live in — at times, all these things can feel messy. Imperfect. Full of friction. And the thought enters the back of your mind that things could be better...
Sometimes, you even see a physical manifestation of how things could be better. You make a new friend, you hear about a new role opening up in your company, you take a trip to a new city. And suddenly you're enamouted.
The grass on the other side of your stressful situation isn't just greener, it's immaculate; untouched. Free from the weeds and patches that your own yard is muddled with.
This feeling is the result of what I call the Clarity Gap — a perceptual distortion that warps our decision-making in predictable but devastating ways.
You know all of your current problems intimately - you see them in high definition. The alternatives might seem clearer, but that's only because you're seeing them from a distance. From far away, everything looks smooth.
That dream job sprouted in your mind as a tweet from someone who just got promoted. That perfect potential partner exists only in a highlight reel, shown to you on a first date. The city you fantasise about is the one you visited on holiday.
So what happens? You overweight the upside of the new thing, and underweight its downsides — or ignore them entirely. You forget that you're comparing a full picture to a postcard.Staring into the mirage
The philosopher Seneca noted that:
"We are more often frightened than hurt; and we suffer more from imagination than from reality."
Our imaginations construct elaborate fantasies of how perfect things could be, while conveniently glossing over the inevitable frictions of any new situation.
The clarity gap explains why the divorce rate among second marriages is higher than first marriages. People leave troubled relationships believing their problems are unique to that relationship, only to discover similar patterns emerging with new partners. The problem wasn't just the relationship — it was also the unrealistic expectations they brought to it.
It explains why so many people quit jobs for "dream opportunities" only to find themselves facing a different set of frustrations. It explains why people move to new cities only to discover that geographical solutions rarely solve psychological problems.
What makes the clarity gap so insidious is that it feels like wisdom. It feels like you're seeing clearly for the first time. "I've finally figured it out," you tell yourself. "This is what I've been missing all along."
The solution isn't to avoid change. It's to close the clarity gap before you jump.
Force yourself to describe the downside of that new option in textured, specific detail. Not the abstract "there might be challenges," but the vivid "what would a terrible Tuesday look like in this scenario?"Seek out the disillusioned insiders — people who once chased the same dream you're considering and walked away disappointed. They'll give you the clarity that your fantasies won't.
Ask yourself: If this decision goes badly, why will it have failed? This pre-mortem forces you to supply the details your imagination has been hiding from you.
Cleaning the glass
The Roman Stoics practised "negative visualisation" — deliberately imagining worst-case scenarios not to cultivate pessimism, but to gain clarity. They understood that real wisdom comes from seeing both sides of any equation.
Ancient mariners navigated by the stars, but they also kept detailed records of dangerous shoals and hidden currents. Knowing the path to your destination means nothing if you don't also know its perils.
There's no honour in learning everything the hard way. Look for lessons from those who have already walked the path before you.
The next time you find yourself mesmerised by a beautiful alternative, remember it's not the alternative itself that's dangerous — it's the resolution gap between what you know and what you imagine.
Bring both options into the same resolution. Force them into the same clarity. Interrogate the unknown with the same rigour you apply to the known. That's not pessimism. That's wisdom.
