What is the bounded rationality model?

Bounded Rationality: Why We Don’t Always Make Perfect Choices (and That’s Okay)

We like to think we’re logical creatures, carefully weighing every option before making a decision. But let’s be honest, how often does that really happen? The truth is, we’re not computers. We’re human, and our brains have limits. That’s where bounded rationality comes in – it’s a model that acknowledges we make decisions with limited information, time, and brainpower.

Think of it this way: imagine trying to choose the absolute best brand of coffee at the grocery store. You could spend hours reading reviews, comparing prices, and analyzing ingredients. But realistically, you’ll probably just grab a bag from a brand you recognize or one that’s on sale. That’s bounded rationality in action!

The idea of bounded rationality was first introduced by Herbert Simon, a brilliant economist who won a Nobel Prize for his work. He basically said, “Hey, people aren’t perfectly rational, and that’s okay!” He argued that we try to be rational, but our rationality is “bounded” by the real world.

So, what are these “bounds” that keep us from making perfect decisions?

• Brain Overload: Our brains can only handle so much information at once. Trying to juggle too many details can lead to decision fatigue.
• Missing Pieces: We rarely have all the facts. There’s always some level of uncertainty involved.
• Tick-Tock: Time is precious! We often need to make decisions quickly, without the luxury of endless research.

Instead of searching for the absolute best option (economists call this “optimizing”), we usually settle for something that’s “good enough.” Simon called this “satisficing,” a blend of “satisfy” and “suffice.” We set a bar for what’s acceptable and pick the first thing that clears it. It’s all about efficiency!

To make things even easier, we rely on mental shortcuts called heuristics. These are like rules of thumb that help us make quick decisions. For example, you might assume that a more expensive product is always better quality. This can be helpful, but it can also lead to biases and mistakes.

You see bounded rationality everywhere:

• Shopping Sprees: When buying clothes, do you really try on every single item in the store? Probably not. You grab a few things that look good and hope for the best.
• Investment Choices: Unless you’re a professional investor, you’re likely relying on advice from friends, past performance, or gut feeling when choosing stocks.
• Restaurant Roulette: Ever felt rushed by a waiter and ordered something you later regretted? That’s bounded rationality messing with your dinner plans!
• Voting Booth Blues: With so many candidates and complex issues, voters often rely on party affiliation or simple sound bites to make their choice.

Even our memories are affected! We tend to remember the things that come to mind most easily, which can skew our perception of events.

Of course, bounded rationality isn’t perfect. Some argue that it focuses too much on what we can’t do, rather than our ability to adapt and make smart choices in messy situations. And let’s be real, sometimes having more information can actually make things more confusing.

But here’s the thing: bounded rationality is a powerful reminder that we’re human. We’re not robots, and we don’t need to be. By understanding our limitations, we can make better decisions, design smarter systems, and cut ourselves some slack along the way. After all, sometimes “good enough” really is good enough.
