Nate Silver

In the week leading up to the 2016 U.S. presidential election, the FiveThirtyEight team predicted that Hillary Clinton had a 64.5% chance of winning the election. Their final prediction on November 8, 2016, gave Clinton a 71% chance to win the 2016 United States presidential election, while other major forecasters had predicted Clinton to win with at least an 85% to 99% probability. Donald Trump won the election. FiveThirtyEight argued it projected a much higher chance (29%) of Donald Trump winning the presidency than other pollsters, a projection which was criticized days before the election by Ryan Grim of The Huffington Post as "unskewing" too much in favor of Trump.

In 2015, Silver appeared on the podcast Employee of the Month, where he criticized Vox Media for "recycling Wikipedia entries" in their content.

In July 2013, Silver sold FiveThirtyEight to ESPN, and Silver became its Editor in Chief. The ESPN-owned FiveThirtyEight launched on March 17, 2014. The site focused on a broad range of subjects under the rubric of "data journalism".

Shortly after the November 4 election, ESPN writer Jim Caple observed, "Forget Cole Hamels and the Phillies. No one in baseball had a more impressive fall than Nate Silver.... [R]ight now Silver is exhausted. He barely slept the last couple weeks of the campaign—'By the end, it was full-time plus'—and for that matter, he says he couldn't have kept it up had the campaign lasted two days longer. Plus, he has his Baseball Prospectus duties. 'We write our [Baseball Prospectus 2009] book from now through the first of the year,' [Silver] said. 'I have a week to relax and then it gets just as busy again. In February 2009 I will just have to find an island in the Caribbean and throw my BlackBerry in the ocean'".

The Times does not release traffic figures, but a spokesperson said yesterday that Silver's blog provided a significant—and significantly growing, over the past year—percentage of Times pageviews. This fall, visits to the Times' political coverage (including FiveThirtyEight) have increased, both absolutely and as a percentage of site visits. But FiveThirtyEight's growth is staggering: where earlier this year, somewhere between 10 and 20 percent of politics visits included a stop at FiveThirtyEight, last week that figure was 71 percent.

She added, "A number of traditional and well-respected Times journalists disliked his work." Later, Sullivan wrote in The Times that "I don't feel so good about not being able to investigate every complaint from every individual reader fully, or about making some misjudgments in individual posts — my Nate Silver commentary, among others, has probably been off-base...".

New York magazine reported that executive editor Jill Abramson "put on a full-court press" to keep Silver at The Times and that "for Abramson, Silver was a tentpole attraction for her favorite subject, national politics, and brought the kind of buzz she thought valuable", but the company's CEO and President Mark Thompson "confirmed that keeping Silver was not at the top of his agenda". The article stated that "the major reason Silver left was because he felt it was Thompson who had not committed to building his franchise. The mixed signals from Thompson and Abramson—his lack of enthusiasm for committing resources to Silver, her desire to keep a major star—frustrated Silver and his lawyer".

When FiveThirtyEight was relaunched under ESPN's ownership on March 17, 2014, Silver outlined the scope of topics that would be covered under the rubric of "data journalism":

We've expanded our staff from two full-time journalists to 20 and counting. Few of them will focus on politics exclusively; instead, our coverage will span five major subject areas — politics, economics, science, life and sports. Our team also has a broad set of skills and experience in methods that fall under the rubric of data journalism. These include statistical analysis, but also data visualization, computer programming and data-literate reporting. So in addition to written stories, we'll have interactive graphics and features. Within a couple of months we'll launch a podcast, and we'll be collaborating with ESPN Films and Grantland to produce original documentary films.

As a CNET reporter wrote on election eve, "Even though Silver launched the site as recently as March, its straightforward approach, daring predictions, and short but impressive track record has put it on the map of political sites to follow. The Washington Post featured Silver in its 14th annual election prediction contest this year, and he'll be reporting on Tuesday night's results with Dan Rather on HDNet".

On July 22, 2013, ESPN announced that it had acquired ownership of the FiveThirtyEight website and brand, and that "Silver will serve as editor-in-chief of the site and will build a team of journalists, editors, analysts and contributors in the coming months."

Silver's first appearance on ABC News as Editor-in-Chief of the new FiveThirtyEight.com was on George Stephanopoulos's This Week on November 3, 2013.

Silver's book, The Signal and the Noise, was published in September 2012. It subsequently reached The New York Times best seller list for nonfiction, and was named by Amazon.com as the No. 1 best nonfiction book of 2012. The Signal and the Noise won the 2013 Phi Beta Kappa Award in Science. The book has been translated into eleven languages: Chinese (separate editions in traditional and simplified characters), Czech, Finnish, German, Italian, Polish, Portuguese, Romanian, Russian, and Spanish.

While blogging for The Times, Silver also worked on his book about prediction, which was published in September 2012. At that time, Silver began to drop hints that after 2012 he would turn his attention to matters other than detailed statistical forecasting of elections. As reported in New York magazine: " 'I view my role now as providing more of a macro-level skepticism, rather than saying this poll is good or this poll is evil,' he says. And in four [years], he might be even more macro, as he turns his forecasting talents to other fields. 'I'm 97 percent sure that the FiveThirtyEight model will exist in 2016,' he says, 'but it could be someone else who's running it or licensing it.'"

In an online chat session a week after the 2012 election Silver commented: "As tempting as it might be to pull a Jim Brown/Sandy Koufax and just mic-drop/retire from elections forecasting, I expect that we'll be making forecasts in 2014 and 2016. Midterm elections can be dreadfully boring, unfortunately. But the 2016 G.O.P. primary seems almost certain to be epic." In late November 2012, Times executive editor Jill Abramson declared her wish to keep Silver and his blog: "We would love to have Nate continue to be part of the New York Times family, and to expand on what he does", she said. "We know he began in sports anyway, so it is not an exclusively political product. I am excited to talk to Nate when he finishes his book tour about ways to expand that kind of reporting."

While publishing numerous stories on the Republican primary elections, in mid-February 2012 Silver reprised and updated his previous Magazine story with another one, "What Obama Should Do Next". This story painted a more optimistic picture of President Obama's re-election chances. A companion article on his FiveThirtyEight blog, "The Fundamentals Now Favor Obama", explained how the model and the facts on the ground had changed between November and February.

Silver published the first iteration of his 2012 general election forecasts on June 7, 2012. According to the model, at that time Barack Obama was projected to win 291 electoral votes—21 more than the 270 required for a majority. Obama then had an estimated 61.8% chance of winning a majority.

On the morning of the November 6, 2012, presidential election, the final update of Silver's model at 10:10 A.M. gave President Barack Obama a 90.9% chance of winning a majority of the 538 electoral votes. Both in summary tables and in an electoral map, Silver forecast the winner of each state. At the conclusion of that day, when Mitt Romney had conceded to Barack Obama, Silver's model had correctly predicted the winner of every one of the 50 states and the District of Columbia. Silver, along with at least three academic-based analysts—Drew Linzer, Simon Jackman, and Josh Putnam—who also aggregated polls from multiple pollsters—thus was not only broadly correct about the election outcome, but also specifically predicted the outcomes for the nine swing states. In contrast, individual pollsters were less successful. For example, Rasmussen Reports "missed on six of its nine swing-state polls".

Considerable criticism during the 2012 elections came from political conservatives, who argued that Silver's election projections were politically biased against Mitt Romney, the Republican candidate for president. For example, Silver was accused of applying a double standard to his treatment of Rasmussen Reports polls, such as a 2010 analysis asserting a statistical bias in its methodology. Josh Jordan wrote in National Review that Silver clearly favored Obama and adjusted the weight he gave polls "based on what [he] think[s] of the pollster and the results and not based on what is actually inside the poll".

The Signal and The Noise was published in the United States on September 27, 2012. It reached the New York Times Best Sellers List as #12 for non-fiction hardback books after its first week in print. It dropped to #20 in the second week, before rising to #13 in the third, and remaining on the non-fiction hardback top 15 list for the following 13 weeks, with a highest weekly ranking of #4. Sales increased after the election on November 6, jumping 800% and becoming the second best seller on Amazon.com.

That Silver accurately predicted the outcome of the 2012 presidential race, in the face of numerous public attacks on his forecasts by critics, inspired many articles in the press, ranging from Gizmodo, to online and mainstream newspapers, news and commentary magazines, business media, trade journals, media about media, and Scientific American, as well as a feature interview on The Today Show, a return appearance on The Daily Show, and an appearance on Morning Joe

In a 2012 interview with Charlie Rose he said, "I'd say I’m somewhere in between being a libertarian and a liberal. So if I were to vote, it would be kind of a Gary Johnson versus Mitt Romney decision, I suppose."

Silver is openly gay. "I've always felt like something of an outsider. I've always had friends but I've always come from an outside point of view. I think that's important. If you grow up gay, or in a household that's agnostic, when most people are religious, then from the get-go, you are saying there are things that the majority of society believes that I don't believe", he told an interviewer in 2012. "When asked what made you feel more of a misfit, being gay or being a geek, he replied, 'Probably the numbers stuff since I had that from when I was six.'" When asked in 2008 if he had noticed people looking at him as a "gay icon", he responded, "I've started to notice it a little bit, although so far it seems like I'm more a subject of geek affection than gay affection".

Although throughout 2011 Silver devoted a lot of attention on his blog to the 2012 Republican party primaries, his first effort to handicap the 2012 Presidential general election appeared as the cover story in The New York Times Magazine a year prior to the election: "Is Obama Toast? Handicapping the 2012 Election". Accompanying the online release of this article, Silver also published "Choose Obama's Re-Election Adventure", an interactive toy that allowed readers to predict the outcome of the election based on their assumptions about three variables: President Obama's favorability ratings, the rate of GDP growth, and how conservative the Republican opponent would be. This analysis stimulated a lot of critical discussion.

In 2010, the FiveThirtyEight blog was licensed for publication by The New York Times. In 2012 and 2013, FiveThirtyEight won Webby Awards as the "Best Political Blog" from the International Academy of Digital Arts and Sciences.

In April 2010, in an assignment for New York magazine, Silver created a quantitative index of "The Most Livable Neighborhoods in New York".

On June 3, 2010, Silver announced on FiveThirtyEight.com,

The New York Times "FiveThirtyEight: Nate Silver's Political Calculus" commenced on August 25, 2010, with the publication of "New Forecast Shows Democrats Losing 6 to 7 Senate Seats". From that date the blog focused almost exclusively on forecasting the outcomes of the 2010 U.S. Senate and U.S. House of Representatives elections as well as state gubernatorial contests. Silver's Times Sunday Magazine feature first appeared on November 19, 2010, under the heading "Go Figure". It was later titled "Acts of Mild Subversion".

Shortly after FiveThirtyEight relocated to The New York Times, Silver introduced his prediction models for the 2010 elections to the U.S. Senate, the U.S. House of Representatives, and state governorships. Each of these models relied initially on a combination of electoral history, demographics, and polling. Silver eventually published detailed forecasts and analyses of the results for all three sets of elections. He correctly predicted the winner in 34 of the 37 contested Senate races. His 2010 congressional mid-term predictions were not as accurate as those made in 2008, but were still within the reported confidence interval. Silver predicted a Republican pickup of 54 seats in the House of Representatives; the GOP won 63 seats. Of the 37 gubernatorial races, FiveThirtyEight correctly predicted the winner of 36.

Silver has been criticized for inaccurate predictions. In January 2010, journalist and blogger Colby Cosh criticized Silver's performance during the Massachusetts special Senate election, saying he was "still arguing as late as Thursday afternoon that [Martha] Coakley was the clear favourite; he changed his mind at midnight that evening and acknowledged that Scott Brown had a puncher's chance." (Brown won the election.)

Silver was named one of The World's 100 Most Influential People by Time in 2009 after an election forecasting system he developed successfully predicted the outcomes in 49 of the 50 states in the 2008 U.S. Presidential election. In the 2012 United States presidential election, the forecasting system correctly predicted the winner of all 50 states and the District of Columbia.

Silver was invited to be a speaker at TED 2009 in February 2009, and keynote speaker at the 2009 South by Southwest (SXSW) Interactive conference (March 2009).

While maintaining his FiveThirtyEight.com website, in January 2009 Silver began a monthly feature column, "The Data", in Esquire as well as contributed occasional articles to other media such as The New York Times and The Wall Street Journal. He also tried his luck in the 2009 World Series of Poker.

The success of his FiveThirtyEight.com blog marked the effective end of Silver's career as baseball analyst, though he continued to devote some attention to sports statistics and sports economics in his blog. In March 2009, he stepped down as Managing Partner of Baseball Prospectus and handed over responsibility for producing future PECOTA projections to other Baseball Prospectus staff members. In April 2009, he appeared as an analyst on ESPN's Baseball Tonight. After March 2009, he published only two "Lies, Damned Lies" columns on BaseballProspectus.com.

In November 2009, ESPN introduced a new Soccer Power Index (SPi), designed by Nate Silver, for predicting the outcome of the 2010 FIFA World Cup. He published a post-mortem after the tournament, comparing his predictions to those of alternative rating systems.

In 2009 through 2012, Silver appeared as a political analyst on MSNBC, CNN and Bloomberg Television, PBS, NPR, Democracy Now!, The Charlie Rose Show, ABC News, and Current TV.

On March 7, 2008, while still writing as "Poblano", Silver established his own blog, FiveThirtyEight.com. Often colloquially referred to as just 538, the website takes its name from the number of electors in the United States electoral college.

On May 30, 2008, Poblano revealed his identity to FiveThirtyEight.com readers. On June 1, 2008, Silver published a two-page Op-Ed article in the New York Post outlining the rationale underlying his focus on the statistical aspects of politics. He first appeared on national television on CNN's American Morning on June 13, 2008.

Later in November 2008, Silver signed a contract with Penguin Group USA to write two books, reportedly for a $700,000 advance.

In March 2008, Silver established his blog FiveThirtyEight.com, in which he developed a system for tracking polls and forecasting the outcome of the 2008 general election. At the same time, he continued making forecasts of the 2008 Democratic primary elections. That several of his forecasts based on demographic analysis proved to be substantially more accurate than those of the professional pollsters gained visibility and professional credibility for "Poblano", the pseudonym that Silver was then using.

Silver's final 2008 presidential election forecast accurately predicted the winner of 49 of the 50 states as well as the District of Columbia (missing only the prediction for Indiana). As his model predicted, the races in Missouri and North Carolina were particularly close. He also correctly predicted the winners of every U.S. Senate race. The accuracy of his predictions won him further acclaim, including abroad, and added to his reputation as a leading political prognosticator.

Barack Obama's 2008 presidential campaign signed off on a proposal to share all of its private polling with Silver. After signing a confidentiality agreement, Silver was granted access to hundreds of polls the campaign had conducted.

Silver's self-unmasking at the end of May 2008 brought him a lot of publicity focused on his combined skill as both baseball statistician-forecaster and political statistician-forecaster, including articles about him in The Wall Street Journal, Newsweek, Science News, and his hometown Lansing State Journal.

In early June he began to cross-post his daily "Today's Polls" updates on "The Plank" in The New Republic. Also, Rasmussen Reports began to use the FiveThirtyEight.com poll averages for its own tracking of the 2008 state-by-state races.

Silver also appeared on The Colbert Report (October 7, 2008 and November 5, 2012), The Daily Show (October 17, 2012 and November 7, 2012), and Real Time with Bill Maher (October 26, 2012).

On November 1, 2007, while still employed by Baseball Prospectus, Silver began publishing a diary under the pseudonym "Poblano" on the progressive political blog Daily Kos. Silver set out to analyze quantitative aspects of the political game to enlighten a broader audience. Silver reports that "he was stranded in a New Orleans airport when the idea of FiveThirtyEight.com came to him. 'I was just frustrated with the analysis. ... I saw a lot of discussion about strategy that was not all that sophisticated, especially when it came to quantitative things like polls and demographics'". His forecasts of the 2008 United States presidential primary elections drew a lot of attention, including being cited by The New York Times Op-Ed columnist William Kristol.

Silver first gained public recognition for developing PECOTA, a system for forecasting the performance and career development of Major League Baseball players, which he sold to and then managed for Baseball Prospectus from 2003 to 2009.

In 2003, Silver became a writer for Baseball Prospectus (BP), after having sold PECOTA to BP in return for a partnership interest. After resigning from KPMG in 2004, he took the position of Executive Vice-President, later renamed Managing Partner of BP. Silver further developed PECOTA and wrote a weekly column under the heading "Lies, Damned Lies". He applied sabermetric techniques to a broad range of topics including forecasting the performance of individual players, the economics of baseball, metrics for the valuation of players, and developing an Elo rating system for Major League baseball.

Between 2003 and 2009, Silver co-authored the Baseball Prospectus annual book of Major League Baseball forecasts, as well as other books, including Mind Game: How the Boston Red Sox Got Smart, Won a World Series, and Created a New Blueprint for Winning, Baseball Between the Numbers, and It Ain't Over 'til It's Over: The Baseball Prospectus Pennant Race Book.

PECOTA projections were first published by Baseball Prospectus in the 2003 edition of its annual book as well as online by BaseballProspectus.com. Silver produced the PECOTA forecasts for each Major League Baseball season from 2003 through 2009.

Having earned a bachelor's degree from The University of Chicago in 2000, Silver has since been awarded six honorary doctoral degrees: from Ripon College (2013), The New School (2013), The University of Leuven (2013), Amherst College (2014), Georgetown University (2017), and Kenyon College (2018).

In 2000, Silver graduated with Honors with a Bachelor of Arts degree in economics from the University of Chicago. He also wrote for the Chicago Weekly News and the Chicago Maroon. He spent his third year at the London School of Economics.

After college graduation in 2000, Silver worked for three and a half years as a transfer pricing consultant with KPMG in Chicago. When asked in 2009, "What is your biggest regret in life?" Silver responded, "Spending four years of my life at a job I didn't like". While employed at KPMG, Silver continued to nurture his lifelong interest in baseball and statistics, and on the side he began to work on his PECOTA system for projecting player performance and careers. He quit his job at KPMG in April 2004 and for a time earned his living mainly by playing online poker.

As a student at East Lansing High School, in 1996 Silver won first place in the State of Michigan in the 49th annual John S. Knight Scholarship Contest for senior high school debaters.

Silver first showed his journalism skills as a writer and opinion page editor for The Portrait, East Lansing High School's student newspaper, from 1993–1996.

Silver showed a proficiency in math from a young age. According to journalist William Hageman, "Silver caught the baseball bug when he was 6.... It was 1984, the year the Detroit Tigers won the World Series. The Tigers became his team and baseball his sport. And if there's anything that goes hand in glove with baseball, it's numbers, another of Silver's childhood interests ("It's always more interesting to apply it to batting averages than algebra class").

Nathaniel Read Silver (born January 13, 1978) is an American statistician and writer who analyzes baseball (see sabermetrics) and elections (see psephology). He is the founder and editor-in-chief of FiveThirtyEight and a Special Correspondent for ABC News.
