Have you ever noticed that at your office or church, a small fraction of people do the lion\u2019s share of the work?<\/p>\n

This is just one manifestation of what\u2019s called the \u201c80\/20 rule.\u201d<\/p>\n

Once you understand the 80\/20 rule, you’ll start seeing it everywhere.<\/p>\n

And be able to use it to significantly improve your life.<\/p>\n

The Birth of the 80\/20 Rule: The Pareto Principle<\/h2>\n

In the late 1890s, an Italian economist named Vilfredo Pareto observed a curious relationship between wealth and population in Italy. His calculations showed that 80% of the land in Italy was owned by just 20% of the population. He did similar surveys in other countries and found the same ratio.<\/span><\/p>\n

Pareto kept digging, and he kept finding this 80\/20 relationship between landownership and total population. It didn’t matter if he looked at a country’s land ownership data in 1890 or 1790. No matter the time period, 80% of the land was owned by just 20% of the population.<\/span><\/p>\n

Pareto didn’t pursue or publicize his discovery, so it died in obscurity. It wasn’t until after World War II that Pareto’s 80\/20 observation started to get the attention it deserved, thanks to a Romanian-born U.S. engineer named Joseph Moses Juran. Juran had read about Pareto’s 80\/20 discovery and thought it could be applied beyond land ownership, including in the manufacturing industry.<\/span><\/p>\n

In 1951, Juran wrote a management manual called the <\/span>Quality Control Handbook<\/span><\/i> in which he referred to Pareto’s discovery as the \u201cPareto principle.” He observed that the Pareto principle operated in crime, accidents, and as he had suspected, manufacturing. In the book, Juran notes one example of how a paper mill discovered that a small number of defect types \u2014 about 12% \u2014 created 80% of the costs for the company. When the mill focused on reducing defects in that 12%, they drastically reduced their overall costs. <\/span><\/p>\n

American companies didn\u2019t pay much attention to Juran, but Japanese companies rebuilding after WWII did. Like the American-born but Japanese-implemented idea of kaizen<\/a>, Juran’s Pareto principle took hold in Japanese manufacturing firms in the 1950s and 1960s, helping Japan become an economic juggernaut. And just as U.S. manufacturers brought kaizen back to American shores to help slumping sales in the 1970s, U.S. companies eventually started applying the Pareto principle too.<\/span><\/p>\n

Economists began studying the principle in earnest in the second half of the 20th century and discovered that you could see it across many domains in life.<\/span><\/p>\n

In baseball, ~20% of a team\u2019s players contribute to ~80% of its wins.<\/span><\/p>\n

In movies, ~20% of films produce ~80% of total box office earnings. <\/span><\/p>\n

In retail, ~20% of all products generate ~80% of a business\u2019s revenue. <\/span><\/p>\n

In computing, ~20% of software code contains ~80% of its errors. <\/span><\/p>\n

You get the idea.<\/span><\/p>\n

In 1997, entrepreneur Richard Koch published The 80\/20 Principle<\/a><\/em> in which he explained the Pareto phenomenon and showed how it can be applied not only in business but in your personal life. He’s credited with popularizing the Pareto principle, or 80\/20 rule.<\/span><\/p>\n

The 80\/20 Rule in a Nutshell<\/h2>\n

\"\"<\/p>\n

In his book, Koch gives this definition of the 80\/20 rule:<\/span><\/p>\n

The 80\/20 Principle asserts that a minority of causes, inputs, or effort usually lead to a majority of the results, outputs, or rewards. <\/span><\/p><\/blockquote>\n

In an even tighter nutshell: <\/span>The 80\/20 rule states that about 20% of causes produce about 80% of outcomes. <\/b><\/p>\n

What this means is that not only does a small proportion of your efforts generate the great majority of your results, the great majority of your efforts are essentially useless. As Koch puts it: \u201c80 percent of what you achieve in your job comes from 20 percent of the time spent. Thus for all practical purposes, four-fifths of the effort\u2014a dominant part of it\u2014is largely irrelevant.\u201d<\/span><\/p>\n

Don’t get too hung up on the exact 80\/20 numbers<\/b>. You don’t see everything break down perfectly into that ratio. The big takeaway from this is that, in the words of Juran, “the vital few” produce the lion’s share of results in life. <\/span><\/p>\n

How to Use the 80\/20 Rule to Improve Your Life<\/h2>\n

Every person I have known who has taken the 80\/20 Principle seriously has emerged with useful, and in some cases life-changing, insights. \u2014Richard Koch<\/span><\/p><\/blockquote>\n

Like I said, once you understand the 80\/20 rule, you start to see it everywhere.<\/span><\/p>\n

About 20% of my contacts make up about 80% of my texts. <\/span><\/p>\n

About 20% of the companies I do business with get about 80% of my expendable income. <\/span><\/p>\n

About 20% of the people in my social network cause about 80% of my personal problems. <\/span><\/p>\n

Koch argues that by recognizing the 80\/20 rule in your life, you can start making decisions to maximize utility and minimize pain.<\/span><\/p>\n

In implementing the rule in your life, keep these two overarching principles in mind:<\/span><\/p>\n
