The power of data analysis數(shù)據(jù)分析的力量

董傳霞

研究人員發(fā)現(xiàn)，在做出艱難決定時，數(shù)據(jù)可以提供可靠的參考信息。通過大數(shù)據(jù)，我們可以從數(shù)百萬面臨與我們類似困境的人那里獲取證據(jù)，從而讓我們的決策更加科學(xué)。

Where should you live？ How should youspend your time？ For centuries， people have reliedon their instincts to figure out the answers to theselife?changing questions. But there is a better waynow. We are living through a data explosion， asvast amounts of information about all aspects ofhuman behaviour have become more and more ac?cessible.

We can use this big data to help determine the best course to chart. Researchers havefound algorithms can be much better than people at making difficult decisions. The powerof data analysis has been proved in the sports and business worlds， too. As it was made fa?mous by the book and movie Moneyball， baseball teams found that algorithms were betterthan managers at picking strategies.

But stats have had surprisingly little impact on our personal lives. One major problemis that good data about lifes biggest personal questions has been difficult to gain. Considerthis question： what makes people happy？ Some have revealed the activities that provide farmore enjoyment than most of us would have guessed， such as exercising， going to a museumand gardening. Then there are things that give us less pleasure than we might assume， such?as playing video games， watching TV and browsing the Internet. Another way to be happieris moving house. The researchers found that when people moved from an unhappy city to ahappier place， their overall mood improved.

There are early days of the data revolution in personal decision?making. A study oftens of millions of children has found the places that increase their future earnings most.Another shows certain cities can improve ones life expectancy. I am not claiming that wecan completely base our lifestyle choices on algorithms， though we might get to that point inthe future. Instead， I am claiming that we can all dramatically improve our decision?makingby consulting evidence from millions of people who face trouble similar to ours via big data.
