Have you ever noticed that the moment you linger a little too long looking at a pair of sneakers online, a discount code magically pops up on your feed? It feels like the internet is reading your mind.
While a surprise discount feels like a win, there is a massive, invisible game happening behind your screen. Tech companies and retailers are using incredibly advanced math to track your behavior. Sometimes it works in your favor, but other times, it’s designed to trick you into spending more money.
Let’s pull back the curtain on how companies use your data, why “overcomplicating” things backfires on them, and how “surveillance pricing” might be costing you or your parents extra cash.
1. The Trap of “Overthinking” (Why Simple is Smarter)
When big tech companies try to predict what you will buy next, they often build massive, incredibly complicated computer programs. They look at your age, your location, what your friends like, the weather outside, and a million other tiny details.
But according to writer Tim Harford in his Financial Times article, “The surprising power of simple predictions”, these experts often fall into a trap: they get so sidetracked by elaborate ideas that they completely overlook the simple, direct approach.
Psychologists have found that simple, straightforward rules (like just looking at your past two purchases) are often betterat predicting the future than super-complex algorithms.
The Takeaway: Just because a system is high-tech and complicated doesn’t mean it’s smart. Sometimes, the most straightforward answer is the right one.

2. From Helpful Coupons to “Surveillance Pricing”
Originally, companies used these tracking systems for good things—like giving you a real-time coupon when you stood in front of a clothing display. But now, that same technology is being turned upside down.
Instead of giving you a discount, companies are starting to practice what Fordham Law professor Zephyr Teachout calls “surveillance pricing” in her Financial Times piece, “The predatory advance of surveillance pricing”. This means a website might show you a different price than the person sitting right next to you, based entirely on your personal data.
Here is how wild it gets:
- The Comparison Penalty: If an algorithm detects that a grandparent doesn’t know how to open multiple tabs to compare prices, it might quote them a higher price for printer ink.
- The Urgency Tax: If you buy children’s cough medicine online, an algorithm might instantly raise the price of diapers. Why? Because it knows a stressed parent with a sick kid is in a hurry and won’t stop to shop around.
- The Vibe Check: Companies can now track how long you search, your GPS history, and even your keystroke dynamics (how fast or heavy you type), which can hint at whether you are tired, anxious, or angry. If the algorithm senses you’re desperate, the price goes up.

Are “Secret Prices” Fair?
In the past, a store posted a price on the shelf, and everyone paid the same amount. Today, information asymmetry—where the seller knows everything about your digital habits, but you know nothing about theirs—means prices are becoming a secret.
As these algorithms get more aggressive, lawmakers and researchers are asking a big question: Should it even be legal for companies to use your private data to squeeze every extra penny out of you?
How to Protect Your Wallet
You don’t have to just sit back and let the algorithms win. Here is how you can fight back:
- Clear your cookies and browsing history or use “Incognito/Private” mode when shopping online so algorithms can’t track your hesitation.
- Don’t buy in a rush if you can avoid it. Taking a break tells the algorithm you aren’t desperate.
- Always comparison shop. Use different devices or browsers to see if the price changes.
The digital world is constantly trying to guess your next move. By understanding how these systems work, you can become a smarter consumer and keep the matrix from playing you.
