"نظر ده هزار مرد هیچ ارزشی ندارد اگر هیچ یک از آنها در مورد موضوع چیزی ندانند"

The main idea here is straightforward: it doesn't matter how many people hold an opinion if they lack knowledge about the topic. Numbers alone don't guarantee value or truth. Imagine you're at a party, and a group of people insists that chocolate is a vegetable because it comes from a plant. Even if everyone agrees, it doesn't change the fact that chocolate isn't a vegetable. Expertise, not majority opinion, is what matters.

This concept has roots going back centuries. Greek philosophers like Socrates and Plato often pointed out that wisdom isn't a popularity contest. They believed that understanding and knowledge trump sheer numbers. So, this quote fits right into a long tradition of valuing informed opinions over popular but uninformed ones.

Let's make this real with an example you might relate to. Think about climate change. Imagine there's a town meeting, and 10,000 residents vote to ignore climate science and continue with policies that harm the environment. If none of these folks are climatologists or even have a basic understanding of climate science, their collective opinion doesn't suddenly become valid just because it's a big number. The consensus among actual climate scientists—those who know the subject—holds far more weight.

So, how do you apply this bit of wisdom in your life? Start by questioning the source of the opinions you hear. Are they coming from people who actually know the subject? If you're making a decision, seek out the views of experts rather than just relying on what most people around you think. In today's world, with social media amplifying all sorts of voices, this is more important than ever.

Now, let's dive into a relatable scenario. Picture yourself at a family gathering. The topic of investing comes up, and your cousin, who's never invested a dime, starts giving everyone advice on which stocks to buy. Others chime in, echoing his sentiment. It feels convincing because so many people are on board. But then, you remember your friend who works in finance. Instead of going with the crowd, you decide to give her a call. She provides you with well-founded advice based on years of experience and data. By seeking out knowledgeable opinions, you not only safeguard your money but also make better-informed decisions.

In a nutshell, don't let the sheer number of opinions sway you. Always check the credibility of the sources. And when you find yourself in a situation where everyone's got an opinion, ask yourself: do they really know what they're talking about? That’s the crux of it.
