Professor Gary Smith has a long history of research projects debunking dubious uses of data in statistical analysis. His book , which was a London Times Book of the Week, warns of the dangers of confusing correlation with causation in statistical analysis. His paper "The Baseball Hall of Fame is Not the Kiss of Death" looks at the .

He has written extensively on financial topics, with research that often shows surprising results, such as the following:

• stocks with clever ticker symbols beat the market,
• stocks going out of the Dow Jones Industrial Average generally outperform the stocks that replace them,
• the stocks with the most optimistic earnings forecasts typically do worse than the stocks with the most pessimistic earnings forecasts, and
• stocks that make ��ǰ��ٳܲԱ�’s most-admired list beat the market, but the stocks that were chosen by Good to Great and In Search of Excellence do not.

His statistical and financial research has been featured in various media, including the New York Times, Wall Street Journal, Wired, NPR Tech Nation, NBC Bay Area, CNBC, WYNC, WBBR Bloomberg Radio, Silicon Valley Insider, Motley Fool, Scientific American, Forbes, MarketWatch, MoneyCentral.msn, Newsweek, Fast Company, OZY and BusinessWeek.

He is the author of 15 books, more than 100 academic papers, and seven software programs on economics, finance and statistics. In addition to teaching at 6V��Ӱ��, he also provides expert analysis and economic consulting.

His book, , is intended to help investors distinguish between valuable financial advice and misleading, misguided and nonsensical assertions.  (Oxford University Press 2018) argues that, in the age of Big Data, the real danger is not that computers are smarter than us, but that we think computers are smarter than us and therefore trust computers to make important decisions for us. The (Oxford University Press, 2019, co-authored with Jay Cordes and winner of the PROSE award for Excellence in Popular Science & Popular Mathematics) is a compilation of grand successes and epic failures that are intended to help data scientists be more effective.  (Oxford University Press, 2020, co-authored with Jay Cordes) argues that we are hard-wired to notice patterns and to think that the patterns we notice are meaningful. This pattern-recognition ability served our distant ancestors well but, in this age of Big Data, patterns are inevitable, usually coincidental, and often misleading.
