(2023·µÂÖÝÄ£Äâ)Where should you live? How should you spend your time? For centuries, people have relied on their instincts to figure out the answers to these life­changing questions£®But there is a better way now£®We are living through a data explosion, as vast amounts of information about all aspects of human behaviour have become more and more accessible£®

We can use this big data to help determine the best course to chart£®Researchers have found algorithms (Ëã·¨) can be much better than people at making difficult decisions£®The power of data analysis has been proved in the sports and business worlds, too£®As made famous by the book and movie Moneyball, baseball teams found that algorithms were better than managers at picking strategies£®

But statistics (ͳ¼ÆÊý¾Ý) have had surprisingly little impact on our personal lives£®One major problem is that good data about life's biggest personal questions has been difficult to gain£®Consider this question: what makes people happy?

There are early days of the data revolution in personal decision­making£®A study of tens of millions of children has found the places that increase their future earnings most£®Another shows certain cities can improve one's life expectancy£®I am not claiming that we can completely base our lifestyle choices on algorithms, though we might get to that point in the future£®I am claiming instead that we can all dramatically improve our decision­making by consulting evidence from millions of people who faced dilemmas similar to ours via big data£®
