Prices change at lightning speed in my country. When you look at restaurant menus, you'll see the numbers crossed out and the new price written on them. When you travel abroad, you'll see the price remains the same as it was two years ago, and it's very difficult to keep up with the pace of price change here. You can sense the hesitation in both the price changer and the payer. This is how I discovered the impact of data on human behavior. My experience demonstrated that financial systems extend beyond market operations because they require people to maintain trust and stability in their economic systems.
