We must rely on shortcuts to understand things
Tuesday, 11 October 2005
The world we live in is infinitely complex. The more humanity understands about it, the more we become amazed at just how intricate it is. Even something as small and simple as the head of a pin can contain thousands of bacteria and chemical reactions, interacting in ways that would take years to understand fully.
Look around you right now, what can you see? Now look again at the detail, the patterns the specks of dust form as they fall on surfaces, the care with which the furniture was put together, the way the light reflects from various surfaces. If you had to write down in detail everything that you can now see, it would probably fill a number of books. And that's just using one sense in one location. Imagine adding to that everything you can smell, hear and feel. Now multiply that by how many other locations and situations you will find yourself in during the day.
And these are just the things you can witness with your raw senses. On top of that, there is a huge amount of activity happening at a microscopic level. There are also countless things occurring in the world right now outside of your view that will certainly affect your life. Perhaps the government is making a decision that will affect you, perhaps a tax inspector is looking over your file, maybe someone who will become a close friend has just moved to your city.
The point is that there's so much going on that could affect us, it's impossible for us to keep track of it all. So how do we cope?
The answer is that we create mental short cuts. Our minds must select from the huge amount of stimulus available to us at any time and decide what's the most relevant. We must try to collect as much information that is important as we can about what's going on that may be affecting us. Perhaps we will read a summary of government decisions in the newspaper. Maybe a friend will fill us in on something that's important.
If we could have all the information we need to make decisions, that would be great, but it's impossible. At best, we can hope to pick up a tiny fraction of it. Then, we must use the tiny fraction of knowledge we have about the world to interpret that tiny fraction of information. In other words, we're operating almost blind.
It's not an ideal situation, but it's a fact of life.
So what are the implications?
This fact means that we can never assume that we've got things completely right. Any police officer knows that five different witnesses to an event can give five different accounts.
We must honestly understand within ourselves that the events and circumstances that affect us are so complex that we can never fully understand them. The truth is, our decisions are based on less than perfect information, and there's a good chance the assumptions we've made in making those decisions are wrong.
Always be prepared that you may be incorrect - that you may have missed some vital fact. And be prepared to change your mind.
Also, understand that other people will likely see things very differently to you. They are also faced with having to create mental shortcuts to explain their infinitely complex reality. Their shortcuts probably differ greatly from your own.
If you find someone else's world view difficult to understand, consider that they have certainly chosen different short-cuts to interpret reality than you have. Looking at it through that prism, the differences between us can become much easier to accept.
 | Is it better to read fiction or non-fiction? | | One of the most popular articles I’ve written on this site so far has been Five excellent mind habits to develop. It’s been generally well received, but I have come in for some criticism for my belief that it’s a better mind habit to read non-fiction than fiction. |  | Many people will do the minimum they can to get by | | Have you ever noticed how many people operate at way below their potential? The genius who works an average office job, the fantastic woman who dates losers, the talented artist who spends all day in front of the TV. Why do such people not put in more effort? |  | Seven rules for sharpening up your thinking skills | | Every day we're flooded with information from all sorts of sources. Much of it is trying to sell us some kind of conclusion: “PMart is the cheapest”, “Global warming is the biggest problem facing humanity”, “Susan thinks you’re cute” and so on. | | Common sense is over-rated | | One thing that's held as a deep belief by many people is the wisdom of 'common-sense' or 'conventional wisdom'. They hold it up as the ultimate truth to which we all should aspire. | | Concentrate on problems you actually have | | We all have things about the world we wish were different. If pressed to write a list of problems we wanted solved, it wouldn't take long for most of us to fill a page or more. Many of our efforts are focussed on fixing the challenges we face - from being hungry to avoiding ending up in poverty. |  | The four measures of financial success | | If you want to do well financially, you must first understand what it is you have to achieve. It's not just a matter of making more money. Instead, there are four factors you must consider. | | Learn how to weigh up opportunity and risk | | Every sensible person lives with one eye on the future. We go to work so we can get paid next week, we go to school so our life chances improve, we try to anticipate bad things that may happen so we can avoid them, we invest in the future in the hope it will pay off. But of course, the time and resources we have to invest in the future are limited. We can't take every opportunity available to us, so we must choose carefully. And with every choice, we take the risk of loss. | | Ten good rules-of-thumb for investing | | I've been investing money for about 14 years now and have had more success than failure along the way. I've also read a large number of books and articles on good investment strategy. Here are my rules-of-thumb if you want to get ahead in the investment game. |  | Most people just want to have their biases reinforced | | When I was in my early twenties, I was pretty sure I had the world figured out. I'd made up my mind about religion, morals, work, politics, love and life. I was convinced that anyone who disagreed with my views on most subjects probably just hadn't thought things through as carefully as me. | | Most people start with a conclusion and then search for the facts to support it | | Most of us realise that the people we deal with in everyday life often aren't rational. They behave in ways that bewilder. They do things that seem immoral, stupid and not in their own interests. They hold beliefs that just seem crazy. |
