Would You Look Up Your Neighbour's Salary If It Took 5 Seconds? A Quarter of Norwegians Did — and the Happiness Gap Between Rich and Poor Grew 29%

Picture it. The guy in the apartment upstairs — the one with the nice bike and the suspiciously frequent vacations — is not a mystery. His income, his net worth and what he paid in tax are sitting in a government database, and you can look. Not guess from his sneakers. Not triangulate from his Instagram. Look. In seconds.

This is not a thought experiment. This is Norway. And an economist who studied what happened when looking got easy found out that it made a lot of people sadder, in a very specific and very relatable way.

The Part Where Norway Was Always Weird About This

Norwegians have technically been able to inspect each other's tax information since the 19th century. The twist is that for most of that time, it was annoying to do. You had to physically go to a tax office or city hall during a limited window and leaf through printed records like a Victorian detective. The information was public. The effort was a deterrent.

Then, in 2001, the records went online.

It caught on the way you'd expect. By 2013, nearly a quarter of the population had used the search sites. And according to the reporting, most of those searches were not people checking on politicians or celebrities. They were ordinary people checking on other ordinary people. Neighbours. Coworkers. Exes. The friend who said she "couldn't afford" the trip.

The records show net income, net wealth and tax. Not a full salary breakdown. Just enough to rank everyone you know.

The Accidental Experiment

Economist Ricardo Perez-Truglia saw 2001 for what it was: a natural experiment nobody had designed. Nothing about the information changed. Only the cost of getting it did.

So he pulled survey data from 1985 to 2013 and did a few things with it:

• Compared Norwegians with strong internet access to those with weak access, since one group could suddenly snoop and the other mostly couldn't.
• Compared Norway to Germany, where tax records weren't public, to rule out some broader early-2000s mood.
• Watched what happened to the relationship between how much people earned and how happy they said they were.

His starting assumption was the standard economics intuition: more information, better choices, happier people. That is not what he found.

29 Percent

After the records went online, the happiness gap between richer and poorer Norwegians widened by 29 percent. The life-satisfaction gap widened by 21 percent.

And the effect showed up exactly where you'd expect if snooping were the cause. Among people with easy internet access, happiness became more tightly tied to income after 2001. Among people who struggled to get online, it didn't.

The mechanism is the oldest one in the book. Income had always been an amount of money. Once anyone could see where they sat relative to their friends, neighbours and coworkers, it also became a rank. And a rank, unlike a number, always has someone above you.

The internet did not invent comparing yourself to the neighbours. It just removed the trip to city hall.

Norway's Fix: Make Snooping Snoop-able

This is my favorite part, because it is so elegantly petty. In 2014, Norway added friction back. The records stayed public, but now, if you look someone up, they can see that you looked.

Anonymous snooping more or less died overnight. Today the system requires you to log in, be at least 16, and you're normally capped at 500 people a month, which is still a lot of people but does suggest someone at the tax office thought about it. Open your ex's record, and a notification lands on your ex's side of the screen. Enjoy.

Perez-Truglia's takeaway was that transparency isn't a simple on/off switch — the details of how information is disclosed decide how people use it. Norway kept the openness and just made the act of comparison itself visible. Slightly different rules, completely different behavior.

For the Record, Transparency Did Some Good

Because this isn't a morality play:

• Separate research tied the move online to an increase of roughly 3 percent in reported income among business owners. Turns out people fudge less when the neighbours can check.
• Nobody has seriously proposed going back to the paper ledgers.
• The 2014 reform didn't reduce what you can see. It just put your name on the viewing.

The Question

The Scandinavia Standard piece ends on a dare, and I'll pass it along: if everyone's income around you were five seconds away, would you actually want to know?

I'd like to say no. I'd like to say I'm above it. I would also, within the hour, have a spreadsheet. The only thing stopping me is that they'd know.
