Reflexivity: when believing changes reality

Imagine a new sweet shop opens in Rohan's street. On the first day, only a few people go in. Then a rumour spreads: "That shop is the best! Everybody is going there!" Now more people come - not because they tasted the sweets, but because they believe it is the best. And here is the strange part. Because a crowd is now there, the shop earns more money. With that money the owner buys better milk, hires more cooks, and makes nicer sweets. So the shop slowly becomes what people believed it already was. The belief did not just describe the shop. The belief helped change the shop.

George Soros, a famous and very aggressive investor, built his whole way of thinking around this one idea. He called it reflexivity. It is a hard-sounding word for a simple thing: what people believe about something can actually change the real thing, and then the changed real thing changes what people believe - round and round, like a wheel that keeps pushing itself. Belief and reality are not separate. They feed on each other.

Most people think reality comes first and belief just copies it, like a mirror copies a face. Soros said the mirror can push back. Sometimes belief comes first, changes reality, and only then does reality "catch up" to the belief. This study is about learning to see that loop - because in markets, it is one of the most powerful and most dangerous forces there is.

Normally we think in a straight line: the shop is good → so people believe it is good. Soros said look for the loop instead: people believe the shop is good → so a crowd comes → so the shop actually gets richer and better → so people believe even more strongly → so an even bigger crowd comes. Each step feeds the next.

Now think about a share price, which is what Soros really cared about. Suppose people start believing a company is going to be huge. So they buy its shares, and the price rises. But a rising share price is not just a number - it can change the real company. With a high share price, the company can borrow money easily, sell new shares to raise cash, attract the best workers, and buy up rivals. So the company really does get stronger - because people believed it would. And now that it is stronger, people believe even more, buy more, and the price rises again.

Do you see the trick? The belief was partly right - but it was right because it made itself right. The price did not simply reflect the company. The price helped build the company. This is reflexivity, and it means a share price is never a calm, honest mirror of a business. It is one player in the game, pushing the very thing it is supposed to be measuring.

So the reading skill is this: when you look at a rising price, do not only ask "is this company good?" Also ask, "is the high price itself making the company look better?" If yes, you are inside a loop - and loops can run much further and much faster than plain facts ever could, in both directions.

illustrative Let us follow a made-up company, call it Kabir Logistics. Calmly, its business is worth about ₹100 a share. Now watch the loop begin. A few clever people believe delivery companies are the future, so they buy, and the price rises to ₹130.

That higher price is not just a number. Kabir Logistics now uses it. It sells a small batch of new shares at ₹130 and collects real cash - say ₹50 crore. With that cash it buys more trucks and opens in three new cities. So the real business grows. Now the company genuinely earns more, which makes the story true, so more people believe and buy, and the price climbs to ₹180.

At ₹180 the company borrows even more cheaply, buys a smaller rival, and hires top managers who only wanted to join a "winning" company. Again the real business improves because the price was high. The price runs to ₹250. Notice what happened: the belief ("this will be big") kept feeding real growth, and the real growth kept feeding the belief. Neither one was purely the cause. They lifted each other, like two people helping each other climb a wall. A person who only asked "is ₹250 fair for today's trucks?" would miss the point entirely - the price and the company were growing together, each pushing the other.

A loop that lifts can also crash. The same feeding works in reverse. If people start to doubt Kabir Logistics, the price falls; a low price means the company cannot raise cash or borrow, so it really does get weaker; the weakness proves the doubters right, so the price falls more. Reflexivity is not a magic up-escalator. It is a loop that runs whichever way belief pushes it - and the down-loop can be brutal and fast. (The next study, on boom and bust, follows exactly this.)

It explains the past better than it predicts the future. Reflexivity is wonderful for understanding a wild rise after it happened. It is much weaker at telling you when a loop will start, stop, or turn around. You can see the wheel spinning, but nobody can tell you the exact moment it will fly off. Many people have lost money betting a loop would break "soon."

Not every belief changes reality. Believing a stone will float does not make it float. Reflexivity works only where belief can actually reach into the real world - through money raised, crowds gathered, confidence given. Where belief cannot touch the facts, the loop does not exist, and you are back to plain reality. Confusing the two is a common mistake.

You can see reflexivity all around you in India, with no special knowledge at all. A tuition teacher who everyone believes is the best gets the most students, so she earns more, hires helpers, and really does teach better - the belief built the reality. A new mall that "everyone is going to" fills up because everyone thinks it is full, so shops rush to open there, and it genuinely becomes the busiest mall. A festival stall that looks crowded pulls in more people simply because it looks crowded.

In our markets, watch for reflexivity in hot new listings, in companies that raise money again and again while their price is high, and in property booms in a single town where rising prices themselves pull in more buyers. The lesson is not "run away from every loop" - some loops build genuinely great things. The lesson is to notice when a price is not just measuring a business but actively shaping it, and to remember that a wheel spinning fast one way can spin just as fast the other way.

• Look for the loop, not the straight line. Ask not only "is this good?" but "is the belief itself making it more true?"
• Watch whether a high price is being used. Raising cash, cheap borrowing, hiring "winners," buying rivals - these turn price into real strength, which is the loop working.
• Remember the loop runs both ways. Whatever belief can build up, doubt can tear down, often faster.
• Don't confuse "understands the past" with "predicts the future." The loop explains wild moves; it cannot time them.
• Check that belief can truly reach reality. If belief cannot change the actual facts, there is no loop - just an ordinary opinion.
